The reduction of the workweek is now a legal reality in Mexico, although its full implementation will take several years. Since March 2026, Article 123 of the Constitution has stipulated that the maximum workweek will gradually decrease from 48 to 40 hours by 2030. Therefore, every company operating in the country must adjust its schedules, payroll, and contracts as the official timeline progresses. This guide explains the origin of the reform, its exact timeline, and the practical obligations employers face in Mexico City and throughout the rest of the country.
1. What is the reduction of working hours and how was it approved?
The reduction of the workweek is a constitutional reform that modifies sections IV and XI of Article 123, paragraph A, to lower the weekly work limit from 48 to 40 hours. The Senate approved the bill on March 3, 2026, and the Official Gazette of the Federation published the decree that same day, making its constitutional component immediately effective.
However, the constitutional reform alone does not immediately change everyday labor relations. For this reason, Congress also approved changes to the Federal Labor Law, which were published in the Official Gazette of the Federation on May 1, 2026. Consequently, there are now two regulatory levels: the constitutional mandate, which sets the ultimate goal, and secondary legislation, which defines the specific mechanisms for transitioning to the new work schedule.
According to the Senate's approved ruling, the reform garnered broad political support, with 104 votes in favor in the April 2026 vote. Subsequently, the Chamber of Deputies ratified the bill on April 22, without substantial changes to the original draft. This legislative consensus largely explains the speed with which both the constitutional decree and its secondary legislation were published, in a period of just two months.
Compared to other recent labor reforms, this initiative enjoyed simultaneous support from both labor unions and business associations, although the latter expressed reservations about the pace of implementation. Therefore, the final text incorporated a phased five-year timeline, rather than immediate implementation, precisely to allow productive sectors time to adapt.
2. Implementation schedule 2026-2030
The reduction schedule is gradual and mandatory for all employers in the country. During 2026, the workweek will remain at 48 hours, as it currently operates. Starting in 2027, the limit will decrease to 46 hours; in 2028, to 44 hours; in 2029, to 42 hours; and finally, in 2030, the target of 40 hours per week will be reached.
It is important to note that the reform expressly prohibits reducing workers' salaries or benefits as a result of reduced hours. In other words, companies must maintain the same full salary even if actual working time decreases. Furthermore, the reform does not differentiate based on company size or economic sector, meaning that both SMEs and multinational corporations must comply with the same schedule.
For example, a company that currently pays an employee a fixed monthly salary for 48 hours per week will have to pay the same salary for 46 actual hours of work by 2027. In practical terms, this equates to an increase in the cost per hour worked, even if the total payroll remains nominally unchanged. Consequently, finance and human resources departments will need to coordinate their budget projections, taking this cumulative effect into account over the next four years.

3. Key changes to the Federal Labor Law following the reduction of the working day
The reform to the Federal Labor Law, published on May 1, 2026, adapts the secondary legal framework to the new constitutional work schedule. This regulatory adjustment modifies provisions regarding overtime, rest periods, and the weekly distribution of working time, in order to provide legal certainty to both employers and employees during the transition period toward 2030.
Overtime and weekly limits
Before the reform, the law allowed a maximum of nine overtime hours per week. Now, that limit increases to twelve hours per week, although these cannot exceed four hours per day distributed over a maximum of four days. Therefore, companies will need to redesign their shift schedules and overtime pay systems, especially in sectors such as manufacturing, logistics, and retail, where extended workdays are common.
This involves reviewing attendance control systems to accurately differentiate between regular and overtime hours as the weekly limit changes each year. Otherwise, miscalculating overtime can lead to incomplete payments and, potentially, labor lawsuits for wage discrepancies.
Mandatory day off and full pay
Furthermore, the reform reinforces the obligation to grant at least one paid day off for every six days worked. It also clarifies that the gradual reduction of working hours should not result in disguised salary cuts or the elimination of previously granted benefits. For its part, the Ministry of Labor and Social Welfare will issue additional operational guidelines as each stage of the 2027-2030 timeline progresses.
It is worth noting that these guidelines could include specific criteria for mixed work schedules, shift work, and work-from-home arrangements—modalities that current law does not always regulate precisely. Consequently, the Ministry of Labor and Social Welfare (STPS) is expected to publish supplementary rules before the first effective reduction takes place in January 2027.
4. Economic and operational impact on companies
The economic impact of this reform varies considerably by sector. Labor-intensive industries, such as manufacturing, construction, and retail, will face greater pressure to maintain production levels with fewer available hours per worker. For example, a plant that currently operates with 48-hour shifts will need to consider additional hiring, technological upgrades, or process redesign by 2027.
Several business associations have requested differentiated transition periods by sector, arguing that a uniform reduction could disproportionately affect industries with lower profit margins. To date, however, the constitutional timetable does not include sectoral exceptions, so any differentiated adjustments would depend on additional reforms to secondary legislation.
On the other hand, sectors with already flexible work schedules, such as some areas of professional services and technology, could absorb the change with less operational friction. However, all companies will need to update their internal attendance policies, timekeeping systems, and payroll structures, since the calculation of overtime and breaks will change as each phase of the official calendar progresses.
Furthermore, it's important to anticipate the effect on productivity per hour worked. Companies that already measure performance indicators by results, rather than by physical hours spent at the workplace, will likely absorb the transition with less financial impact than those organizations still anchored to traditional timekeeping systems.
5. Sectors with the highest risk of non-compliance
Certain sectors face a particular risk of non-compliance during the transition. For example, the export manufacturing sector, with its 48-hour rotating shift schedules, will need to rethink its operational organization starting in 2027. Similarly, the retail sector, which operates with extended hours on weekends, will have to review the distribution of mandatory rest periods to avoid penalties.
Similarly, the construction sector, where working hours are typically tied to project deadlines, will face difficulties in reconciling reduced hours with contractual timelines agreed upon with clients. Therefore, it is recommended that these industries begin an internal assessment now, rather than waiting until each deadline in the 2027-2030 calendar approaches.
The call center and customer service sector, which operates with staggered 24-hour shift schedules, will also face additional challenges in distributing mandatory breaks without disrupting service. Finally, the agricultural sector, subject to harvest seasons with intensive workdays, will need to negotiate accumulated work schedules in advance that comply with the new weekly limit.
In all these cases, the recommendation is the same: document each operational adjustment with legal backing, instead of improvising informal solutions that later prove difficult to defend in the event of a labor inspection or a lawsuit from a worker.

6. What should companies do to prepare?
First, it's advisable to conduct an audit of current schedules to identify areas and positions most affected by the reform. This audit should include a detailed breakdown by department, shift, and contract type, so the company has accurate data before negotiating any adjustments with unions or employee representatives. Additionally, it's recommended to model the financial impact of each stage of the schedule, considering potential hiring or investments in automation.
A third step involves mapping positions with rotating shift schedules or frequent overtime, as these will concentrate the majority of the legal and financial risk during the transition. Internal legal departments, for their part, should establish their own regulatory review schedule now, aligned with each effective date of the official 2027-2030 calendar.
Contractual and payroll adjustments
It is also prudent to review collective and individual employment contracts to ensure they accurately reflect the new limits on working hours and overtime. Similarly, payroll and attendance systems must be updated before 2027 to avoid errors in calculating earnings and overtime pay. Finally, it is advisable to train middle managers on the new regulations, as they typically manage the schedules of operational staff directly.
These middle managers, in their daily work, are the ones who authorize overtime, approve breaks, and resolve attendance issues. Consequently, inadequate training at this hierarchical level often results in operational non-compliance, even when corporate policies are correctly written on paper.
7. Legal risks of non-compliance
Failure to comply with the new work schedule may result in lawsuits before the Conciliation and Arbitration Board or the corresponding labor courts, in addition to administrative sanctions imposed by the Ministry of Labor and Social Welfare. For example, exceeding the permitted overtime limits or failing to grant the mandatory day of rest may generate significant employer liability.
Similarly, reducing salaries or benefits under the pretext of decreased working hours constitutes a direct violation of the constitutional reform. Consequently, companies that implement salary adjustments without legal justification risk costly labor disputes and reputational damage. For their part, unions and workers' representatives have already announced that they will closely monitor compliance with each phase of the official timeline.

Conclusion
This reduction in the workday will gradually transform the relationship between companies and workers until 2030. Although 2026 still operates under the 48-hour workweek, the regulatory clock is already ticking for every employer in Mexico. Therefore, anticipating this through internal audits, payroll adjustments, and training is more cost-effective than facing penalties or labor disputes later on.
Companies that begin their transition plan from 2026 onward, rather than waiting until the last quarter of 2027, will have more time to negotiate with unions, redesign processes, and train their teams without operational pressure. At Baráibar & Asociados, we support companies through every phase of this regulatory transition process, from the initial assessment to the final contract update.
Frequently asked questions about reducing working hours
When does the reduction in working hours come into effect? The schedule is gradual: 48 hours in 2026, 46 in 2027, 44 in 2028, 42 in 2029 and 40 hours per week from 2030 onwards, according to the decree published in the DOF on March 3, 2026.
Does a reduction in hours imply a lower salary? No. The constitutional reform expressly prohibits reducing workers' salaries or benefits as a consequence of the gradual reduction of the weekly working hours.
How many overtime hours can be worked now? The limit increased from nine to twelve hours per week, distributed in a maximum of four hours per day for up to four days, according to the reform to the Federal Labor Law published on May 1, 2026.
Which companies must comply with this reform? All companies operating in Mexican territory, regardless of size or economic sector, must comply with the constitutional schedule for reducing working hours until 2030.
What if a company doesn't meet the deadline? You may face labor lawsuits, administrative sanctions from the Ministry of Labor and Social Welfare, and employer liability for violations of working hours and overtime limits.
Should I update my employment contracts now? It is recommended. Reviewing collective and individual contracts, as well as payroll systems, before 2027 avoids calculation errors and reduces legal risks during the transition.

Esta Ley avanza en el Congreso mexicano como la respuesta legislativa más ambiciosa frente a un delito que hasta hoy se castiga de forma desigual en cada estado. Por primera vez, el país tendrá criterios homologados de investigación, sanción y reparación del daño. Además, la iniciativa llega acompañada de penas de hasta 70 años de prisión y de un catálogo amplio de agravantes. Para despachos, empresas y organizaciones civiles, entender el alcance de esta reforma ya no es opcional. Este artículo explica su origen constitucional, su contenido normativo y el calendario legislativo previsto para agosto de 2026. Asimismo, se revisan las implicaciones prácticas para quienes operan en Ciudad de México y en el resto del país, desde despachos hasta áreas corporativas de cumplimiento.
1. ¿Qué es la Ley General de Feminicidio y por qué surge ahora?
Es la legislación que el Congreso de la Unión debe expedir para unificar los tipos penales, las sanciones y los protocolos de investigación del feminicidio en todo el territorio nacional. Actualmente, cada entidad federativa define el delito de manera distinta, lo cual genera criterios dispares y, en consecuencia, impunidad en muchos casos. Por esta razón, la presidenta Claudia Sheinbaum envió al Congreso, el 15 de julio de 2026, una iniciativa de 62 artículos y 12 transitorios distribuidos en cinco títulos.
Dicha iniciativa no nace de manera aislada. Antes bien, responde a años de exigencia social y a recomendaciones de organismos internacionales de derechos humanos. Asimismo, se apoya en cifras oficiales que documentan un patrón persistente de violencia feminicida en varias regiones del país. De igual manera, busca cerrar espacios de interpretación que hoy permiten confundir un feminicidio con un homicidio doloso simple, con las consecuencias procesales que ello implica.
Organismos como la Comisión Interamericana de Derechos Humanos han señalado en distintos informes que la falta de homologación normativa en México favorece la impunidad estructural. Por lo tanto, la nueva ley busca también atender observaciones internacionales pendientes desde hace más de una década. Cabe destacar que el mecanismo elegido, una ley general y no una simple reforma al Código Penal Federal, obliga a todas las entidades federativas a adoptar el mismo piso normativo, sin excepción.
2. Antecedentes: la reforma constitucional al artículo 73
El fundamento jurídico de esta ley no apareció de un día para otro. En abril de 2026, el Senado aprobó por unanimidad, con 119 votos, una reforma al artículo 73 constitucional para facultar al Congreso a legislar en materia de feminicidio como ley general. Posteriormente, el Diario Oficial de la Federación publicó el decreto correspondiente el 6 de mayo de 2026, y este entró en vigor al día siguiente.
A partir de esa fecha, el Congreso cuenta con 180 días naturales para expedir la legislación secundaria. En consecuencia, el plazo vence a inicios de noviembre de 2026, lo cual explica la celeridad con la que avanza el proceso legislativo actual. Cabe destacar que este mecanismo de “ley general” ya se utiliza en México para otros delitos de alto impacto, como el secuestro y la desaparición forzada, precisamente porque permite establecer un piso mínimo de protección aplicable en los 32 estados.
Este mismo modelo normativo ha demostrado resultados mixtos en el pasado. Por ejemplo, la Ley General en materia de Desaparición Forzada, vigente desde 2017, logró unificar protocolos de búsqueda, aunque su implementación estatal siguió siendo desigual por falta de presupuesto. En consecuencia, los especialistas anticipan que el verdadero reto de la Ley General de Feminicidio no será su aprobación legislativa, sino su instrumentación efectiva en fiscalías con capacidades técnicas y financieras muy distintas entre sí.

3. Contenido clave de la Ley General de Feminicidio: sanciones y agravantes
La propuesta enviada al Senado contempla penas de entre 50 y 70 años de prisión para quien cometa feminicidio. Además, introduce sanciones que van más allá de la privación de la libertad, entre ellas la pérdida de la patria potestad sobre hijos en común y la pérdida de derechos sucesorios respecto de los bienes de la víctima.
Penas de prisión y circunstancias agravantes
El proyecto contempla diecinueve circunstancias agravantes que incrementan la pena hasta en una mitad. Por ejemplo, se agravará el delito cuando la víctima estuviera embarazada, tuviera alguna discapacidad, ejerciera el periodismo, fuera defensora de derechos humanos o se encontrara en situación de movilidad. De esta manera, la ley busca reconocer contextos de vulnerabilidad que agravan la responsabilidad penal del agresor.
Otras agravantes contempladas incluyen la relación de parentesco o confianza entre víctima y agresor, el uso de violencia sexual previa, y la exposición pública del cuerpo de la víctima con fines de intimidación. Por su parte, los jueces deberán motivar de forma expresa cada agravante aplicado, lo cual busca evitar criterios discrecionales que hoy generan sentencias contradictorias entre circuitos judiciales distintos.
Igualmente relevante resulta la imprescriptibilidad del delito. En otras palabras, el paso del tiempo no extinguirá la posibilidad de investigar, sancionar o exigir justicia, ni tampoco la obligación de reparar el daño. Esta característica coloca al feminicidio en la misma categoría que otros delitos que el derecho internacional considera de especial gravedad.
Reparación integral del daño y pérdida de derechos
Por su parte, el título cuarto de la iniciativa regula los derechos de las víctimas indirectas y el mecanismo de reparación integral. Este mecanismo contempla componentes económicos, psicológicos y simbólicos, alineados con estándares interamericanos de derechos humanos. Sin embargo, la ley también exige que las fiscalías estatales cuenten con protocolos de investigación obligatorios y homogéneos, lo cual representa un reto operativo considerable para procuradurías con recursos limitados.
También, se prevé la creación de un registro nacional de casos de feminicidio, con información desagregada por entidad y por tipo de agravante. Este registro permitiría, en teoría, medir con mayor precisión la efectividad de las fiscalías y detectar patrones regionales de violencia. No obstante, especialistas en política pública advierten que un registro nacional solo será útil si cuenta con presupuesto etiquetado y mecanismos reales de rendición de cuentas.
4. Cronología legislativa: del Senado a la votación final
El proceso legislativo ha avanzado en etapas bien definidas. Primero, en abril de 2026, el Pleno del Senado aprobó la reforma constitucional habilitante. Después, en mayo, el Ejecutivo publicó el decreto en el DOF. Enseguida, el 15 de julio, la presidenta envió la iniciativa de ley general propiamente dicha. Finalmente, el 22 de julio, el Senado inició el análisis formal en comisiones, y el 29 de julio la Comisión para la Igualdad de Género aprobó la ruta crítica de discusión.
De acuerdo con el calendario legislativo difundido por el propio Senado, el dictamen final se elaborará entre el 25 y el 30 de agosto de 2026. Por lo tanto, aún no existe una ley general vigente al momento de esta publicación; lo que existe es una reforma constitucional en vigor y una iniciativa en discusión avanzada. No obstante, dado el respaldo político con el que cuenta la propuesta, es previsible que el Congreso concluya el proceso dentro del plazo constitucional de 180 días.
Vale la pena recordar que el plazo constitucional vence a inicios de noviembre de 2026. Por consiguiente, incluso si el Senado aprueba el dictamen a finales de agosto, todavía restará la discusión y votación en la Cámara de Diputados, así como el proceso de publicación en el DOF. En este sentido, resulta razonable estimar que la ley general entre en vigor entre septiembre y noviembre de 2026, salvo que surjan controversias que retrasen el dictamen.
5. Impacto para empresas, instituciones y sociedad civil
La nueva ley no solo interesa a fiscalías y tribunales. Las empresas, especialmente aquellas con áreas de cumplimiento, recursos humanos y responsabilidad social corporativa, también deberán revisar sus protocolos internos. Por ejemplo, los mecanismos de atención a víctimas de violencia de género dentro del entorno laboral tendrán que alinearse con los nuevos estándares de homologación.
Así mismo las instituciones educativas y las organizaciones de la sociedad civil que colaboran con fiscalías en la atención a víctimas necesitarán actualizar sus protocolos de canalización. Asimismo, los despachos jurídicos que representan a víctimas o a personas imputadas deberán familiarizarse con los nuevos tipos penales y agravantes, dado que estos modificarán la estrategia procesal en cada caso. Por su parte, las áreas de comunicación corporativa deberán cuidar el lenguaje institucional al abordar públicamente este tema, evitando la revictimización.
También conviene mencionar a las aseguradoras y a las administradoras de fondos de pensiones, dado que la pérdida de derechos sucesorios prevista en la ley afectará directamente los procesos de sucesión de bienes y de pago de seguros de vida en casos de feminicidio. Del mismo modo, las instituciones bancarias que gestionan fideicomisos familiares deberán prever protocolos internos para atender estos escenarios conforme a la nueva legislación.

6. ¿Qué deben hacer las empresas para prepararse ante la nueva ley?
En primer lugar, conviene realizar una auditoría de los protocolos internos de atención a la violencia de género, incluyendo canales de denuncia y rutas de acompañamiento psicológico. Adicionalmente, es recomendable capacitar a las áreas de recursos humanos y de cumplimiento sobre los nuevos tipos penales, agravantes y plazos de imprescriptibilidad que introduce la reforma.
Un tercer punto, con frecuencia subestimado, consiste en revisar las pólizas de seguro de vida y los fideicomisos corporativos que puedan verse afectados por la pérdida de derechos sucesorios del agresor. Los comités de ética empresarial, por su parte, deberían incorporar explícitamente el feminicidio y sus agravantes dentro de los códigos de conducta interna, sobre todo en organizaciones con operación en varios estados.
Recomendaciones específicas para el sector privado
Por ejemplo, las empresas con presencia en varios estados deberán homologar sus políticas internas conforme al nuevo estándar federal, en lugar de replicar criterios estatales dispersos. También resulta prudente revisar los contratos de prestación de servicios con terceros, sobre todo cuando existan cláusulas relacionadas con protocolos de seguridad o de atención a incidentes de violencia. Finalmente, es aconsejable mantener comunicación con asesores legales especializados, de manera que la organización pueda anticipar reformas a leyes secundarias, como el Código Penal Federal y los códigos penales estatales.
7. Comparación con la legislación penal vigente
Hoy, el feminicidio ya está tipificado en el Código Penal Federal y en la mayoría de los códigos estatales. Sin embargo, las penas, los elementos del tipo y los agravantes varían considerablemente entre entidades. Por ejemplo, algunos estados contemplan penas máximas de 45 o 50 años, mientras que otros no reconocen ciertas circunstancias agravantes que la nueva ley sí incorporará.
Por su parte, la Ley General de Feminicidio busca eliminar precisamente esa dispersión normativa. De este modo, una vez vigente, funcionará como piso mínimo obligatorio para todas las legislaciones locales, las cuales deberán armonizarse en un plazo determinado por los artículos transitorios. Cabe destacar que esta armonización no ocurrirá de manera automática, sino que exigirá reformas específicas en cada congreso estatal.
Estados con códigos penales más rezagados en la materia probablemente enfrentarán mayor presión legislativa y presupuestal para cumplir el nuevo estándar federal a tiempo.

Conclusion
La Ley General de Feminicidio representa un cambio estructural en la manera en que México investiga y sanciona este delito. Todavía falta la votación final, prevista para finales de agosto de 2026, pero el rumbo legislativo ya está trazado. Por lo tanto, anticiparse a sus efectos, tanto en el ámbito penal como en el corporativo, resulta la estrategia más prudente para despachos, empresas y organizaciones sociales.
Mientras el Congreso concluye el dictamen, conviene revisar protocolos internos, actualizar políticas de recursos humanos y capacitar a los equipos legales sobre los nuevos tipos penales y agravantes. De lo contrario, las organizaciones podrían enfrentar contingencias legales o reputacionales una vez que la ley entre en vigor. En Baráibar & Asociados damos seguimiento puntual a este proceso legislativo para mantener informados a nuestros clientes y anticipar cada fase de su implementación.

The regularization of national water concessions formally began on July 16, 2026, one day after the publication of the corresponding agreement in the Official Gazette of the Federation. Signed by the Director General of the National Water Commission, Efraín Morales López, the instrument opens a twelve-month window for individuals, ejidos (communal landholdings), municipalities, and irrigation districts to bring their expired water rights up to date between 2009 and July 2026. However, this opportunity comes with concrete risks: those who do not act within the deadline could face the expiration of unused water volumes. Therefore, understanding the true scope of the agreement is essential for any company with operations that depend on water resources in Mexico.
What does the water concession regularization agreement establish?
The instrument published on July 15, 2026, implements temporary administrative simplification measures. It applies to concession and allocation titles whose validity expired between January 1, 2009, and the agreement's entry into force. The condition is that the interested party had not requested an extension, or had submitted it after the deadline. The measures cover domestic, urban public, agricultural, livestock, and aquaculture uses. Agro-industrial use is expressly excluded, in accordance with Article 2, Section 17, of the Regulations of the National Water Law.
Twelve months of validity: from July 16, 2026 to July 15, 2027.
Regarding the beneficiaries, the agreement distinguishes three profiles. Irrigation districts, irrigation units, and ejidos (communal landholdings) can regularize their water usage without volume limits. Similarly, state and municipal governments that directly provide water services are exempt from volume limits. Individuals, however, have a limit of one million cubic meters per year. It is worth noting that this scheme aligns with the 2024-2030 National Water Plan, whose fourth pillar seeks comprehensive and transparent water management.
The program's legal basis is anchored in Article 24 of the National Water Law, which regulates concession extensions, and in the law's regulations. For its part, the authority justifies the measure as a direct response to what it has termed the "black market" for water rights, that is, the informal transfer of rights without the knowledge or control of the National Water Commission (Conagua).
🔗 EXTERNAL LINK: See the full agreement in the Official Gazette of the Federation (DOF) → https://dof.gob.mx/nota_detalle.php?codigo=5793639&fecha=15/07/2026
Requirements to access the regularization of water concessions
Thirteen requirements are necessary to qualify for the program, and none are optional. Among the most important are having a property in operation for the last two years, having a meter installed, and being up-to-date on payments for the last five fiscal years. Additionally, the applicant must not have any pending administrative sanction proceedings related to the property title they intend to regularize.
This documentary requirement is not accidental. Consequently, the Federal Government seeks to regulate the concession system and reduce the informal market for permits to extract groundwater. Centralized control falls to Conagua through the National Public Water Registry, which will compile information on ownership, authorized volumes, and actual water use reported by each concession holder.
Minimum recommended documentation
- Certified copy of the original concession or assignment title
- Proof of payment of fees for the last five fiscal years
- Photographic and technical evidence of the capture work in operation
- Certificate of no outstanding debt with the National Water Commission
- Report of extracted volumes, when a meter is installed.
In practice, several errors delay the process: submitting the title without proof of payment for the last five years, or failing to report that the water intake structure has changed location without formal registration with Conagua (the National Water Commission). For example, if the authority detects inconsistencies between the reported volume and the actual usage observed in the field, the process can be suspended until the discrepancy is clarified. Therefore, it is advisable to gather all the necessary documentation from the beginning, rather than waiting for a later request.

Risk of expiration if the regularization of water concessions is not addressed in time
Anyone who chooses to ignore this administrative window faces a quantifiable risk. The agreement instructs Conagua to verify, for two years after its entry into force, the actual use of the allocated water volumes. For its part, the authority will conduct reconciliation processes to adjust the authorized volume to the volume actually used, taking into account national water security and the marginalization index of the populations involved.
For businesses, this means that unused water rights could be subject to expiration. Therefore, it is crucial to maintain robust documentation regarding water usage, metering, and timely payment of fees. If the entire allocated volume is not used, companies can also initiate procedure CONAGUA-01-019 to interrupt the expiration of the rights corresponding to the unused volumes.
Let's consider the case of a medium-sized agro-industrial plant that was granted a specific water allocation a decade ago, but which today consumes only a fraction of that amount. Under the new system, that difference could be returned to the national water supply without any compensation. Therefore, conducting an internal audit of actual consumption becomes a preventative measure, not just an administrative one.

Impact of the regularization of water concessions on industrial and infrastructure sectors
Although this first phase is aimed at non-industrial uses, its effects extend to sectors with higher water consumption. The December 2025 reform to the National Water Law replaced traditional mechanisms for transferring water rights with reassignment schemes subject to the direct intervention of the National Water Commission (Conagua). It also incorporated a national water reserve fund to reincorporate unused volumes and limited the validity of the water guarantee to a maximum of five years.
The new scheme centralizes the reassignment of water rights in Conagua.
These measures have direct relevance for water-intensive manufacturing, mining, energy, and data center projects. Any water rights management for new developments must be processed directly with Conagua, with no option to acquire water volumes through private transfer of water rights with a change of use.
A concrete example illustrates the change. Before the reform, a manufacturing company could acquire additional water volumes by purchasing a water rights from another concessionaire, with a simple subsequent notification to Conagua (the National Water Commission). Today, however, that same operation requires demonstrating to the authority that the corresponding basin has actual water availability, which can considerably lengthen the planning time for a new industrial project.
Sectors with greater exposure to the new regime
- Manufacturing and data centers: They require constant volumes and depend entirely on the direct allocation of Conagua.
- Mining: It faces greater scrutiny under the new water crimes regime incorporated in the December 2025 reform.
- Real estate development: You should verify the actual availability of water before committing to new projects.
- Agribusiness: Although excluded from this first stage, it must anticipate future phases of sectoral regularization.
Therefore, legal and corporate compliance departments must incorporate this new regime into their water risk assessment before initiating any project that requires a new concession.
Implications for irrigation districts, communal lands, and agricultural operations
Irrigation districts, irrigation units, and ejidos are among the main beneficiaries of the agreement, as they can regularize their water titles without volume limits. However, this advantage does not exempt these entities from complying with the thirteen general requirements, including proof of an operational project for the past two years.
In practice, many irrigation districts operate infrastructure built decades ago, with documentation scattered across various agencies. Therefore, the first recommended step is to reconstruct the technical file for each permit before contacting Conagua directly. Otherwise, the lack of an organized file can prolong the process beyond what is expected.
Furthermore, the volume reconciliation stipulated in the agreement will take into account food security and the marginalization index of the beneficiary populations. Consequently, municipalities that directly provide drinking water services should take advantage of the absence of volume limits to regularize all of their supply sources, thus avoiding future disputes with the National Water Commission.

Legal context: from the National Water Law to the General Water Law
For nearly three decades, the 1992 National Water Law regulated the granting of concessions under a primarily administrative approach, with little emphasis on tracing actual water use. However, this approach changed with the December 2025 reform, which substantially modified the National Water Law itself and gave rise to the new General Water Law.
The General Water Law, published on December 11, 2025, is based on a different premise: water is no longer understood as a mere commodity but is expressly recognized as a human right. This paradigm shift translates into concrete mechanisms, such as the national water reserve fund and the limitation of the guaranteed quota to five years.
In this context, the agreement to regularize water concessions serves as the first operational instrument of this new policy. It does not modify the existing legal framework, but it does put it into practice by offering a concrete administrative process for clearing the registry of expired permits. It is also worth noting that this transition coincides with a strengthening of the sanctions regime, aimed at penalizing unauthorized water extraction and the misuse of hydraulic infrastructure.
For businesses, understanding this regulatory evolution is not an academic exercise. How Conagua interprets and applies the water concession regularization agreement in the coming months will set the tone for the program's subsequent stages. Therefore, it is advisable to closely monitor the operational criteria that the authority publishes, rather than assuming that the text of the agreement contains all the relevant information for the process.

How to prepare for the new water policy in Mexico
The regularization of water concessions should be understood as part of a broader policy of traceability and state control over water resources. For companies, this means proactively reviewing the status of each concession title and assessing the advisability of joining the program before its expiration on July 15, 2027.
Recommended steps before applying for regularization
- Internally audit all current or expired concession and allocation titles.
- Verify the installation and calibration of extraction meters.
- Gather proof of payment of fees for the last five fiscal years.
- Confirm that there are no open sanctioning procedures before Conagua.
- Submit the application with specialized legal support before the twelve-month period expires.
It is also advisable to review any pending concession, extension, or modification procedures, as the agreement allows for the registration of favorable resolutions issued since April 1, 2019, in the National Public Water Registry. Otherwise, the risk of losing unused volumes will increase as Conagua progresses with its verification processes.

Conclusion
The regularization of water concessions represents a limited-time opportunity, not a mere administrative formality. Those with permits that expired between 2009 and July 2026 must act within the twelve-month validity period of the agreement to avoid the expiration of unused water volumes. Furthermore, the new water traceability regime requires companies in all sectors to strengthen their documentation submitted to Conagua (the National Water Commission). Finally, having specialized legal support makes all the difference between taking advantage of the regularization window and facing costly expiration proceedings in the future.
Frequently asked questions about the regularization of water concessions
Who can access the regularization of water concessions in 2026?
Irrigation districts, irrigation units, ejidos, federal entities, municipalities and individuals with titles that expired between 2009 and July 2026 can access it, in accordance with the agreement published in the DOF on July 15, 2026 and article 24 of the National Water Law.
What happens if I don't regularize my concession within the deadline?
The unused volume may be subject to a declaration of forfeiture. Conagua will verify actual usage during the two years following the entry into force of the agreement, in accordance with the powers granted to it by the current National Water Law.
Does the agreement apply to industrial use concessions?
Not directly, since the agreement expressly excludes agro-industrial use volumes, in accordance with article 2, section 17, of the Regulations of the National Water Law, although the general traceability regime does affect industrial sectors.
How long does the regularization agreement remain valid?
It is valid for 365 calendar days starting on July 16, 2026, so the term ends on July 15, 2027, as established in the agreement itself published in the Official Gazette of the Federation.
What documents do I need to start the process with Conagua?
Among other documents, a certified copy of the title, proof of payment of fees for the last five fiscal years, evidence of the work in operation and proof of no debt are required, in accordance with the thirteen requirements set out in the agreement.
Can I avoid expiration if I don't use my entire allocated volume?
Yes, it is possible to initiate the CONAGUA-01-019 procedure to interrupt the expiration of rights related to unused volumes, provided that a justified cause is proven before the corresponding authority.

Mochila Segura inconstitucional es la declaración que emitió la Primera Sala de la Suprema Corte de Justicia de la Nación al resolver que este programa carece de un marco legal que sustente la revisión obligatoria de las pertenencias de los estudiantes. Sin embargo, la resolución no prohíbe toda intervención escolar: distingue entre revisiones arbitrarias y actuaciones justificadas por sospecha razonable o consentimiento informado. Por lo tanto, padres de familia y autoridades educativas necesitan entender con precisión qué pueden y qué no pueden hacer las escuelas hoy en México. Esta guía explica, con lenguaje accesible, los alcances reales de la resolución y las acciones concretas disponibles para cada parte involucrada.
¿Qué significa que Mochila Segura sea inconstitucional?
La Primera Sala de la Suprema Corte resolvió el amparo en revisión 41/2020 el 3 de febrero de 2021. Por una mayoría de cuatro votos, la Corte concedió el amparo a un padre y una madre que se inconformaron porque sus hijos fueron sometidos a revisiones de mochilas sin su consentimiento expreso. Asimismo, el criterio quedó plasmado en la tesis 1a. V/2022 (10a.), con número de registro digital 2024146, publicada el 4 de febrero de 2022 en el Semanario Judicial de la Federación.
El argumento central de la Corte es sencillo de explicar. Ninguna ley federal ni estatal regula de manera específica cómo, cuándo y bajo qué condiciones el personal escolar puede revisar las pertenencias de un estudiante. En consecuencia, aplicar el operativo de forma generalizada y obligatoria transgrede el derecho a la privacidad y a la intimidad de niñas, niños y adolescentes, reconocido por el artículo 16 constitucional.
Aunque la resolución se emitió hace varios años, su relevancia práctica sigue vigente en 2026, pues buena parte de las escuelas mexicanas no ha actualizado sus reglamentos internos conforme a este criterio. Por lo tanto, cada nuevo ciclo escolar representa una oportunidad para que padres y directivos revisen si los protocolos vigentes realmente cumplen con los estándares fijados por la Primera Sala, en lugar de asumir que un documento redactado hace una década sigue siendo válido.

El artículo 16 constitucional y el derecho a la privacidad de los menores
El fundamento de la resolución se encuentra en el artículo 16 de la Constitución Política de los Estados Unidos Mexicanos, que protege a toda persona frente a actos de molestia que no estén debidamente fundados y motivados por autoridad competente. Aunque el personal escolar no es propiamente una autoridad en sentido estricto, la Corte extendió esta lógica de protección a los espacios educativos, reconociendo que niñas, niños y adolescentes también son titulares plenos del derecho a la privacidad e intimidad.
Este razonamiento no es menor. Durante años, prevaleció la idea de que los menores, por estar bajo la tutela de la escuela durante la jornada, tenían un nivel reducido de protección frente a este tipo de intervenciones. Sin embargo, la Primera Sala revirtió esa presunción al establecer que cualquier restricción a la privacidad de un estudiante debe estar justificada, ser proporcional y contar con un mínimo de regulación clara, tal como ocurriría con cualquier otro acto de molestia dirigido a una persona adulta.
De igual manera, la resolución dialoga con el principio del interés superior de la niñez, reconocido en el artículo 4 constitucional y en la Convención sobre los Derechos del Niño. Este principio exige que, al ponderar la seguridad escolar frente a la privacidad individual, la autoridad y las instituciones educativas busquen la alternativa que menos afecte los derechos del menor, sin sacrificar por ello la protección de la comunidad escolar en su conjunto.

¿Qué pueden y qué no pueden hacer las escuelas hoy?
Tras la declaración de Mochila Segura inconstitucional, ninguna escuela puede imponer revisiones obligatorias y generalizadas sin sustento legal ni consentimiento. De igual manera, tampoco puede condicionar el ingreso a clases a la aceptación automática de una revisión sin informar previamente a los padres sobre sus alcances. Esta prohibición aplica tanto a escuelas públicas como privadas, pues el derecho a la privacidad de los menores no depende del tipo de institución.
No obstante, la Corte fue clara en que la inconstitucionalidad del programa no significa que las escuelas queden indefensas ante riesgos reales. Las instituciones educativas conservan la facultad de intervenir cuando existe sospecha razonable, es decir, elementos objetivos que hagan pensar que un estudiante porta un objeto peligroso o una sustancia prohibida. Igualmente, en situaciones de riesgo inminente para la comunidad escolar, la actuación de mayor intensidad resulta justificada, aun sin autorización previa de los padres.
Derechos de los padres de familia frente a las revisiones escolares
Para las familias, la resolución de la Corte se traduce en derechos concretos y exigibles. En primer lugar, ningún colegio puede revisar las pertenencias de un menor sin que exista consentimiento expreso, libre e informado de los padres o tutores, o bien, una causa justificada de sospecha razonable o riesgo inminente. Además, ese consentimiento debe solicitarse de manera clara, sin presión y con información suficiente sobre el alcance del operativo.
Las familias suelen asumir que firmar el reglamento escolar al inicio del ciclo autoriza automáticamente cualquier tipo de revisión, y eso es jurídicamente incorrecto; el consentimiento debe ser específico, informado y revocable, no una cláusula genérica perdida entre decenas de páginas. Esta precisión resulta relevante porque, en la práctica, muchos planteles siguen operando bajo esquemas de autorización general que no cumplen con los estándares fijados por la Primera Sala.
Por su parte, los padres también tienen derecho a solicitar que la escuela documente por escrito los protocolos de revisión vigentes, así como a exigir que cualquier intervención respete la dignidad e integridad emocional del estudiante revisado. Adicionalmente, es recomendable que las asociaciones de padres de familia soliciten a la dirección escolar una sesión informativa sobre los nuevos protocolos, en lugar de esperar a que ocurra un incidente para conocerlos. De esta manera, toda la comunidad escolar comparte el mismo entendimiento sobre los límites y alcances de una revisión legítima.
¿Cuándo sí procede una revisión aunque Mochila Segura sea inconstitucional?
Resulta fundamental distinguir entre lo prohibido y lo permitido. La declaración de Mochila Segura inconstitucional no elimina toda posibilidad de revisión; simplemente exige que exista una base legítima para realizarla. Por ejemplo, si un docente observa que un estudiante oculta un objeto punzocortante, esa sospecha razonable justifica una intervención inmediata, incluso sin consentimiento previo de los padres.
De la misma manera, cuando existe evidencia de que se cometió o está por cometerse un delito dentro del plantel, las autoridades escolares pueden actuar con mayor grado de intervención para proteger a la comunidad, siempre que la actuación sea proporcional al riesgo identificado. En cambio, las revisiones aleatorias, sistemáticas y sin causa específica —como las que caracterizaban al operativo original— permanecen prohibidas, sin importar que se realicen con buenas intenciones.
Pensemos en dos escenarios distintos. En el primero, un prefecto revisa mochila por mochila a todo un grupo escolar al inicio de clases, sin motivo particular; esta práctica quedó prohibida por la declaración de Mochila Segura inconstitucional. El segundo escenario es distinto: un compañero reporta que vio a un estudiante específico guardar un objeto sospechoso en su mochila. Esa información concreta constituye sospecha razonable y habilita una revisión focalizada, siempre que se documente el motivo y se informe a los padres lo antes posible.

¿Qué hacer si tu hijo fue revisado sin consentimiento?
Si una escuela realizó una revisión sin sustento legal ni consentimiento informado, los padres cuentan con vías legales concretas. La primera opción consiste en presentar una queja formal ante las autoridades educativas competentes, exigiendo la suspensión del protocolo irregular. Adicionalmente, cuando la violación resulta grave o reiterada, es posible promover un juicio de amparo indirecto, tal como lo hicieron los padres del caso que dio origen a esta tesis.
Cabe destacar que el plazo para interponer un amparo contra actos de esta naturaleza corre a partir de que el afectado tiene conocimiento del acto reclamado, por lo que actuar con prontitud incrementa las posibilidades de éxito. Asimismo, documentar el incidente —con fechas, testigos y comunicaciones con el plantel— fortalece cualquier reclamo posterior, sea administrativo o judicial. Igualmente, conviene solicitar por escrito una explicación formal a la dirección del plantel antes de escalar el caso a instancias superiores, ya que muchas controversias se resuelven en esta etapa temprana sin necesidad de litigio.
Por otra parte, cuando la revisión derivó en una sanción disciplinaria contra el estudiante, como una suspensión, esa sanción también puede impugnarse si se originó en una intervención ilegal. En consecuencia, la irregularidad en el origen de la prueba puede invalidar las consecuencias que de ella se derivaron, un argumento que conviene desarrollar con acompañamiento legal especializado.
Errores comunes en los protocolos escolares actuales
A pesar de la claridad del criterio de la Corte, muchas instituciones educativas conservan protocolos que no se ajustan a la nueva interpretación constitucional. Un error frecuente consiste en mantener cláusulas de “autorización general” firmadas al inicio del ciclo escolar, que pretenden cubrir cualquier tipo de revisión futura sin especificar supuestos concretos. Este tipo de cláusula difícilmente resistiría un análisis judicial, pues no constituye un consentimiento informado en sentido estricto.
Otro error común ocurre cuando el personal escolar realiza revisiones por rutina, sin documentar la sospecha razonable que las motivó. De ahí que, ante una eventual queja, la escuela no pueda acreditar que actuó dentro de los supuestos permitidos por la tesis 1a. V/2022 (10a.). Por último, algunas instituciones delegan las revisiones a personal sin capacitación específica, lo que incrementa el riesgo de que la intervención se realice de forma desproporcionada o poco respetuosa con la dignidad del estudiante. De ahí que resulte recomendable que la revisión de protocolos escolares se realice con acompañamiento jurídico, en lugar de replicar formatos genéricos utilizados por otras instituciones sin adaptarlos al criterio vigente de la Suprema Corte.
Recomendaciones para instituciones educativas
Las escuelas también deben adaptarse a este nuevo estándar. En primer lugar, conviene diseñar un protocolo escrito que distinga con claridad los supuestos de sospecha razonable, riesgo inminente y revisión consensuada, evitando fórmulas genéricas que no resistirían un escrutinio judicial. Por otra parte, capacitar al personal docente y administrativo sobre estos límites reduce el riesgo de conflictos legales y refuerza la confianza de las familias en la institución.
Llos colegios que actualicen sus protocolos antes de un incidente, en lugar de reaccionar después de una queja, reducen de forma considerable su exposición legal y fortalecen la relación con los padres de familia. Finalmente, cualquier revisión que se realice, aun bajo causa justificada, debe documentarse de manera inmediata para acreditar que se actuó conforme a los criterios de la Corte.

Conclusion
La declaración de Mochila Segura inconstitucional no es un permiso para que las escuelas dejen de cuidar la seguridad escolar, ni tampoco una prohibición absoluta de toda revisión. Se trata, en cambio, de un límite claro: cualquier intervención sobre las pertenencias de un estudiante requiere consentimiento informado, sospecha razonable o riesgo inminente debidamente acreditado. Además, tanto padres como escuelas se benefician de contar con protocolos claros y asesoría legal oportuna. Finalmente, conocer estos límites evita conflictos innecesarios y protege, al mismo tiempo, los derechos de los menores y la seguridad de la comunidad escolar. En este sentido, tanto las familias como las instituciones educativas ganan cuando el diálogo sobre seguridad escolar se construye sobre reglas claras, en lugar de operativos improvisados que terminan judicializándose.
Preguntas frecuentes sobre Mochila Segura inconstitucional
¿Por qué la SCJN declaró que Mochila Segura es inconstitucional?
Porque el programa carecía de un marco legal que regulara cómo, cuándo y bajo qué condiciones podían revisarse las pertenencias de los estudiantes, lo que transgredía el derecho a la privacidad reconocido por el artículo 16 constitucional, según la tesis 1a. V/2022 (10a.).
¿Las escuelas ya no pueden revisar mochilas nunca?
Sí pueden, siempre que exista consentimiento informado de los padres, sospecha razonable de un riesgo concreto, o una situación de peligro inminente para la comunidad escolar, conforme al criterio de la Primera Sala de la Suprema Corte.
¿Qué es la sospecha razonable en este contexto?
Son elementos objetivos y verificables, distintos de una simple corazonada, que llevan a pensar que un estudiante porta un objeto peligroso o una sustancia prohibida, permitiendo una intervención de menor intensidad sin consentimiento previo.
¿Qué puedo hacer si mi hijo fue revisado sin mi autorización?
Puedes presentar una queja formal ante la autoridad educativa correspondiente y, en casos graves o reiterados, promover un juicio de amparo indirecto, siguiendo el mismo camino legal que dio origen a la tesis 1a. V/2022 (10a.).
¿El consentimiento firmado al inscribir a mi hijo autoriza cualquier revisión?
No necesariamente. El consentimiento debe ser específico, informado y revocable; una cláusula genérica dentro del reglamento escolar no siempre cumple con los estándares de validez exigidos por la Primera Sala de la Corte.
¿Esta tesis aplica igual a escuelas públicas y privadas?
Sí. El derecho a la privacidad y a la intimidad de niñas, niños y adolescentes protegido por el artículo 16 constitucional no distingue entre instituciones públicas y privadas, por lo que el criterio aplica a ambos tipos de plantel.

| Manuel Baráibar Tovar contributed to the construction of jurisprudence on the principle of immediacy in criminal proceedings in the Mexican oral accusatory system. |
This principle is one of the cornerstones of the oral adversarial system established in Article 20 of the Constitution. Essentially, it requires that the judge who presided over the presentation of evidence in the oral trial be the same judge who issues the sentence. However, this is not always the case, and the procedural consequences of violating it are significant.
Knowing the criteria of the Supreme Court of Justice of the Nation (SCJN) on this principle is essential for defendants and their defenders in Mexico.
Principle of immediacy in criminal law within the accusatory system
The principle of immediacy in criminal proceedings establishes that all hearings in the oral trial must be held before the judge, who cannot delegate their functions to another person. This guarantee ensures the judge's direct contact with the evidence: they hear statements from witnesses, experts, and the accused, observe their behavior, and form their conviction based on what they perceive during the hearing.
Far from being a mere formality, this principle constitutes a substantive guarantee. Its purpose is to protect the defendant's right to be tried by the same judge who directly reviewed the evidence.
Furthermore, the adversarial oral system was created to correct the shortcomings of the inquisitorial model, in which the investigating judge rarely handed down the sentence. In this context, the principle of immediacy in criminal proceedings strengthens judicial impartiality and the reliability of decisions.
What do the Constitution and the National Code say about principio de inmediación penal?
Article 20 of the Political Constitution of the United Mexican States establishes that criminal justice shall be accusatory and oral, governed by the principles of publicity, adversarial proceedings, concentration, continuity, and immediacy. Therefore, the principle of immediacy in criminal proceedings is not merely a jurisprudential criterion: it has constitutional status, and its violation can compromise the validity of the entire trial.
For its part, the National Code of Criminal Procedure (CNPP) elaborates on this principle in Article 9, stating that no procedural action may be delegated. Additionally, Article 67 of the CNPP stipulates that when a judge is replaced, the actions previously taken must be repeated before the new judge.
The jurisprudence of the SCJN interprets this mandate strictly.

How has the Supreme Court of Justice of the Nation (SCJN) defined the principle of immediacy in criminal proceedings?
The Supreme Court of Justice of the Nation has issued important rulings on the scope of the principle of immediacy in criminal proceedings. Specifically, it maintains that it would be pointless for the judge to hear the parties, take the defendant's statement, and question the witnesses if this is done in isolated instances or before different judges.
|
“The principle of immediacy in criminal proceedings is the difference between a genuine oral trial and a sham trial in the adversarial system. When the judge who hands down the sentence was not the one who heard the evidence, the decision loses its most fundamental procedural legitimacy. The Supreme Court of Justice of the Nation (SCJN) has been clear on this point, and at Baráibar & Asociados we have successfully invoked it in cases where attempts were made to replace the judge after the evidence had been presented. My participation in shaping the legal precedent allowed me, with great pride, to contribute to the development of the interpretation that now protects this principle in the Mexican adversarial system.”
— Manuel Baráibar Tovar, Esq., Founding Partner, Baráibar & Associates
|
The Supreme Court of Justice of the Nation (SCJN) also determined that the principle of immediacy in criminal proceedings operates as an essential procedural rule. This implies the presence of the judge throughout the entire oral trial hearing, from the presentation of evidence to the pronouncement of the sentence.
The judge who hears the oral trial must be the same one who hands down the sentence.
The rule is clear: the judge presiding over the oral trial must issue the sentence.
The Supreme Court of Justice of the Nation (SCJN) maintains that this requirement cannot be waived for reasons of administrative convenience or the workload of the Judiciary. If the judge is removed, reassigned, or replaced for any reason after the presentation of evidence has begun, the oral trial must be held again before the new judge.
Furthermore, a violation of the principle of immediacy in criminal proceedings produces a specific procedural consequence: the nullity of the oral trial. This means that a guilty verdict issued by a judge who did not witness the presentation of evidence can be overturned through an appeal or a direct amparo proceeding.
However, there is an important clarification that the Supreme Court of Justice of the Nation (SCJN) has established. This principle cannot be absolutely demanded at all stages of the process. The reason is that the constitutional reform prioritized guaranteeing judicial impartiality: a judge who knows all the background information from the beginning could lose objectivity when issuing a ruling.
When is the principle of immediacy in criminal proceedings violated?
Three main allegations of rape.
The jurisprudence of the SCJN identifies three main assumptions of violation of the principle of criminal immediacy.
First assumption. The judge who hands down the sentence is different from the one who presided over the presentation of evidence, without the evidence having been presented again before the new judge.
Second assumption. The judge was not present at all the hearings of the oral trial, either because he delegated his presence to another official or because he was unjustifiably absent during the presentation of relevant evidence.
Third assumption. There are excessive and unjustified interruptions between sessions of the oral trial that disrupt the concentration and continuity of the proceedings. In these cases, the judge loses a direct and complete understanding of the evidence.
An oral trial divided into sessions widely separated from each other can compromise the principle of immediacy in criminal proceedings, especially when the judge is replaced between sessions.

Procedural consequences: the nullity of the oral trial
- As a rule, the violation of the principle of immediacy in criminal proceedings gives rise to the nullity of the oral trial.
- As a resultThe trial must be held again, with the full presentation of the evidence before the new judge, who will be the same one who issues the sentence.
- This nullityHowever, it is not updated automatically, but must be alleged and proven through the corresponding resources and means of appeal.
- The Supreme Court also He pointed out that the nullity resulting from the violation of the principle of immediacy in criminal proceedings does not always imply the immediate release of the accused.
Limits of the principle of immediacy in criminal proceedings according to the SCJN
As noted, the principle of immediacy in criminal proceedings cannot be absolutely demanded at all stages of the criminal process. The Supreme Court of Justice of the Nation (SCJN) has recognized that this principle operates primarily in the oral trial phase, not in prior stages such as the investigation, the initial hearing, or the preliminary hearing. Therefore, the fact that different judges are involved in these stages does not in itself violate the principle of immediacy.
Furthermore, the Supreme Court of Justice of the Nation (SCJN) has determined that the principle of immediacy in criminal proceedings cannot be invoked to demand that the same judge preside over the case from its very inception. Strictly speaking, the principle requires that the judge presiding over the presentation of evidence in the oral trial be the same judge who hands down the sentence.
In that regard, it should be noted that the replacement of the judge before the formal start of the oral trial does not violate the principle, provided that the new judge presides over the trial hearings in their entirety and is the one who ultimately delivers the sentence.

Conclusion: the principle of immediacy in criminal proceedings protects the legitimacy of the trial
The principle of immediacy in criminal proceedings is a constitutional guarantee that ensures that the oral trial is what it should be: a direct and personal evaluation of the evidence by the person who will make the most important decision regarding the defendant's freedom. Its violation is not a procedural technicality. It is a real infringement of the right to a fair trial.

Frequently asked questions about the principle of immediacy in criminal proceedings
1. In which article of the Constitution is the principle of immediacy in criminal proceedings found?
The principle of immediacy in criminal proceedings is enshrined in Article 20 of the Political Constitution of the United Mexican States, which establishes the principles of the oral adversarial system: publicity, adversarial proceedings, concentration, continuity, and immediacy. Its procedural development is found in Article 9 of the National Code of Criminal Procedure (CNPP).
2. What happens if the judge presiding over the oral trial is replaced before issuing a sentence?
If the trial judge is replaced before sentencing, the trial must be held again before the new judge, including the full presentation of evidence. If a sentence is issued without complying with this requirement, it constitutes a violation of the principle of immediacy in criminal proceedings and is subject to appeal. Legal basis: Articles 9 and 67 of the National Code of Criminal Procedure; Supreme Court of Justice of the Nation (SCJN) ruling ADR 492/2017.
3. Does a violation of the principle of immediacy in criminal proceedings lead to the release of the accused?
Not necessarily. A violation of the principle of immediacy in criminal proceedings results in the annulment of the oral trial and requires a new one. This does not imply an automatic acquittal of the accused, but rather that the process must be restarted respecting the guarantees of the adversarial system. However, in certain cases, it may justify a review of the pretrial detention measure while the proceedings are being restarted.
4. Does the principle of immediacy in criminal proceedings apply during the investigation stage?
No. The Supreme Court of Justice of the Nation (SCJN) has determined that the principle of immediacy in criminal proceedings operates primarily during the oral trial phase, not in prior stages such as the investigation, the initial hearing, or the intermediate stage. Therefore, it is valid for different judges to preside over these stages without this constituting a violation. Legal basis: SCJN rulings ADR 492/2017 and ADR 1644/2021.
5. How is a violation of the principle of immediacy in criminal proceedings challenged?
It may be challenged by means of an appeal against the final judgment, arguing a violation of procedural law that affects the defense and impacts the outcome of the ruling. Alternatively, it may be raised in a direct amparo proceeding. Legal basis: Articles 467, section IV, and 468 of the National Code of Criminal Procedure; Article 170 of the Amparo Law.
6. Can it be invoked if the judge was absent during a hearing?
Yes. If the judge was not present at all hearings of the oral trial—either because they delegated their presence to another official or because they were absent during the presentation of key evidence—this may constitute a violation of the principle of immediacy in criminal proceedings. The defense must accurately document the absence and demonstrate that it affected the outcome of the trial. Legal basis: Article 20, Section A, Paragraph V, CPEUM; Article 9 CNPP.
