Mexico's New Data Protection Law: A Comprehensive Analysis of the 2025 LFPDPPP Reform
Mexico has fundamentally transformed its data protection landscape with the enactment of a new Federal Law on the Protection of Personal Data Held by Private Parties (LFPDPPP) on March 21, 2025. This sweeping reform not only modernizes the country's privacy framework but also restructures the entire regulatory apparatus governing data protection and transparency.
The End of INAI: A Historic Shift in Governance
The most dramatic change brought by the new law is the dissolution of the National Institute of Transparency, Access to Information, and Protection of Personal Data (INAI), an autonomous regulatory body that had overseen data protection matters since 2014. As of March 21, 2025, these responsibilities have been transferred to the Ministry of Anticorruption and Good Governance (Ministry), a governmental body reporting directly to the executive branch.
This transition marks a fundamental shift from autonomous oversight to executive branch control, raising significant concerns among legal experts and civil society organizations. Critics worry that data protection oversight will no longer be independent or impartial, given the Ministry's budget constraints, reporting structure, and appointment processes.

Key Changes and Enhancements
Expanded Scope and Definitions
The 2025 LFPDPPP introduces several critical updates to the regulatory framework:
Broader Application: The scope of the LFPDPPP now expressly includes data processors, meaning that anyone involved in the processing of personal data is directly subject to the law. This expansion ensures that all parties in the data processing chain bear direct legal responsibilities.
Updated Definitions: Key terms such as "consent," "personal data," "privacy notice," and "publicly accessible sources" have been updated. Notably, information that has been obtained unlawfully or originates from illegal sources will not be considered a publicly accessible source.
New Data Protection Principles
The law incorporates modern privacy principles that align with international best practices:
- Data Minimization: Organizations must limit data collection to what is necessary for specified purposes
- Purpose Limitation: Personal data must only be used for the purposes for which it was collected
- Proactive Accountability: Data controllers must demonstrate compliance with the law's requirements
Enhanced Individual Rights
Data subjects retain their rights of access, rectification, cancellation, and objection ("ARCO Rights"), but with significant enhancements:
Expanded Access Rights: The right of access now explicitly includes not only the right of data subjects to access their personal data but also to obtain information on the conditions and generalities of the processing.
Enhanced Rectification: Data subjects may now request the correction of personal data not only when they are inaccurate or incomplete but also when they are outdated.
Automated Decision-Making Protections: The right to rectification of inaccurate data and the right to object now extend to automated decision-making processes that produce significant effects.
Stricter Confidentiality Requirements
Anyone involved in the processing of personal data (including employees and external service providers) will be required to maintain confidentiality even after their relationship with the data controller ends. Organizations must implement robust internal policies, training programs, and contractual clauses to ensure ongoing compliance.
Implementation Challenges and Concerns
Regulatory Uncertainty
The effective implementation of the LFPDPPP will largely depend on the issuance of technical standards and complementary regulatory guidelines. The executive branch will have 90 days to issue the necessary amendments to the new FLPPDPP regulations, creating a period of uncertainty for businesses seeking compliance guidance.
International Transfer Complications
The law does not establish clear criteria or specific mechanisms for international transfers of personal data, creating uncertainty for multinational operations. This gap presents significant challenges for global businesses operating in Mexico or transferring data across borders.
Weakened Oversight Mechanisms
Several aspects of the new framework have raised concerns among privacy advocates:
Reduced Transparency Requirements: Simplified privacy notices are no longer required to inform data subjects of the categories of personal data being collected, nor to notify them of their ARCO rights or of changes to privacy practices.
Expanded Implied Consent: The reaffirmation of implied consent expands the scenarios in which a data subject's authorization may be presumed, potentially weakening transparency.
Broader Processing Exemptions: The LFPDPPP allows for the processing of personal data without consent in a broader range of situations, including those based on general legal provisions or non-binding mandates.
Enforcement and Sanctions
The LFPDPPP significantly broadens the range of administrative sanctions for non-compliance. However, until the relevant regulatory provisions are issued, significant uncertainty will persist regarding the criteria, scope, and proportionality of such sanctions.
As of March 21, 2025, any resolutions issued by the new Ministry may be challenged through an amparo lawsuit before specialized courts in the field, representing a shift from the previous administrative court system.
Business Impact and Compliance Requirements
Immediate Action Items
Organizations operating in Mexico must take several immediate steps to ensure compliance:
Data Audit: Each organization should perform a comprehensive audit of the data sources it uses, in order to identify those that do not comply with the new legal definition and could represent a legal risk.
Contract Review: Contracts with suppliers and business partners should be reviewed and updated, precisely delimiting the roles of data controller and data processor in accordance with the updated definition of the law.
Privacy Notice Updates: Companies should review their privacy notice and, if necessary, adjust it to the provisions of the FLPPDPP including, where appropriate, replacing references to the INAI.
Heightened Compliance Standards
The law imposes higher standards of legality, transparency, security and proactive responsibility. Organizations must demonstrate not only compliance with specific requirements but also their commitment to protecting personal data through comprehensive governance frameworks.
International Context and Comparisons
The 2025 LFPDPPP represents Mexico's effort to modernize its data protection framework in line with global trends. While incorporating elements similar to the European Union's GDPR, such as expanded individual rights and accountability principles, the law's integration of public and private sector requirements creates a unique hybrid approach.
The dissolution of INAI and transfer of authority to the executive branch, however, runs counter to international best practices that emphasize independent regulatory oversight. This structural change may impact Mexico's ability to achieve adequacy decisions with other jurisdictions and could complicate international data transfer arrangements.
Looking Forward: Challenges and Opportunities
Transitional Period Complexities
All pending matters that were unresolved by INAI will now be handled by the Secretariat of Anti-Corruption and Good Governance. This will likely result in delays in resolution times and may lead to discrepancies in the criteria applied to resolve cases.
The transitory regime also establishes a 90-calendar-day suspension period, starting from the effective date of the Decree, for all proceedings, legal remedies, and procedures under the responsibility of the now-defunct INAI.
Specialized Court System
The transitory regime provides for the creation of specialized federal courts for data protection matters within 120 calendar days from the LFPDPPP's effective date. This development could enhance the quality of judicial decision-making in data protection cases, provided the courts develop appropriate expertise.
Future Regulatory Development
The success of Mexico's new data protection framework will largely depend on the quality and clarity of implementing regulations. The Ministry of Anticorruption and Good Governance faces the challenging task of developing technical standards, enforcement guidelines, and complaint procedures that provide legal certainty while protecting individual rights.
Conclusion
Mexico's 2025 data protection reform represents both an opportunity and a challenge. While the new LFPDPPP strengthens individual rights and modernizes privacy protections, the dissolution of INAI and concentration of authority within the executive branch raises serious questions about regulatory independence and effectiveness.
For businesses, the law demands immediate attention to compliance requirements while navigating a period of regulatory uncertainty. Success will require proactive engagement with the evolving legal framework, robust internal governance structures, and close monitoring of implementing regulations as they emerge.
The international business community will be watching closely to see how Mexico's new approach to data protection governance affects cross-border data flows and whether the country can maintain its position as a trusted partner in the global digital economy. The coming months will be critical in determining whether this ambitious reform achieves its stated goals of enhanced protection and regulatory coherence, or whether the structural changes undermine the very rights it seeks to protect.
This analysis is based on information available as of August 2025. Given the evolving nature of implementing regulations and enforcement practices, organizations should continue to monitor developments and seek specialized legal counsel for specific compliance requirements.
