The Secretariat of Security and Civilian Protection (SSPC) was formally created through a reform to the
Organic Law of the Federal Public Administration published on 30 November 2018, during the transition to the presidency of
Andrés Manuel López Obrador. The reform introduced Article 30-Bis, which defined the new secretariat’s powers and responsibilities. Its Internal Regulations were later published on 30 April 2019, establishing its administrative structure. With its creation, the SSPC absorbed most federal security functions previously managed by the
Secretariat of the Interior (SEGOB), including responsibilities left after the dissolution of the former
Secretariat of Public Security in 2013 under President
Enrique Peña Nieto. In September 2022, Congress approved secondary legislation transferring operational and administrative control of the National Guard from the SSPC to the
Secretariat of National Defense (SEDENA), effectively reducing the SSPC’s operational capabilities and leaving it largely as a policy-designing institution. In April 2023, the
Supreme Court of Justice of the Nation (SCJN) ruled the transfer unconstitutional, holding that the Constitution explicitly placed the National Guard under the SSPC. The decision temporarily required the federal government to return command authority to the civilian secretariat, though the executive continued pressing for military integration of the corps. In the final days of the López Obrador administration,
Congress approved a constitutional reform package, published on 30 September 2024 and effective the following day, that amended several constitutional articles to permanently place the National Guard under SEDENA, effectively concluding the legal dispute over its command. Under the administration of President Claudia Sheinbaum, Congress approved an additional constitutional amendment to Article 21, ratified and published in December 2024. The reform redefined the SSPC as a coordination-focused civilian security authority, expanding its responsibilities in intelligence, oversight, and crime prevention. It granted the SSPC authority to carry out investigative functions, which were previously reserved exclusively to the
Attorney General´s Office, allowing the development of intelligence-based inquiries to support criminal cases. The amendment also empowered the secretariat to audit federal security funds allocated to state governments and placed it in charge of the newly created National Intelligence System, positioning the agency as the central coordinating body of federal security policy while SEDENA retained command of uniformed security forces. == Organizational structure ==
