The Official Journal of the Federation published on June 1, 2009 a decree adding a second paragraph to Article 16 of Mexico's Constitution, which became effective the day after publication. The amendment is designed to raise the privacy protection of personal data to the highest level of Mexico's national legislation. Through this reform, a new Constitutional level guarantee known as the "Guarantee of Protection of Personal Data" is created, which grants and recognizes the rights of citizens to access, correct, cancel or oppose the management of their personal data. The reform not only protects personal data at the Constitutional level, but also assures the national reach of the protection of personal data and information, whether in the public or private sector. Any entity or public or private individual that manages, has access to or provides personal data must provide for its protection and guarantee the privacy rights of the holders of such data. Finally, it is important to note that the amendment introduces principles designed to cover any exceptions to exercising privacy rights, under which such rights would be subject to opposition for national security (such as the integrity, stability and survival of the state), provisions pertaining to public order and safety, (such as the prevention, investigation, prosecution and sentencing of crimes) and public health (such as prevention, control and eradication of health risks) and the protection of rights of third parties. The genesis of the reform is an amendment to Article 6 of the Mexican Federal Constitution published in the Official Journal of the Federation on July 20, 2007, which established for the first time the right to protection of personal data as a right distinct from that of access to personal information. Given the practical implications that could arise from exercising this right, a new regulation will be necessary which, in addition to the Federal Law of Transparency and Access to Public Information, will provide a broader and more regulated treatment of this right, and potential exceptions to such right, imposing sanctions for any violations and providing for criminal offenses for such violations.

On May 29, 2009 the new Organic Law of the Federal Attorney General's Office (Ley Orgánica de la Procuraduría General de la República or by its initials in Spanish, PGR), was published in the Official Journal of the Federation, which substitutes the previous law enacted on December 27, 2002 and formalizes the closing of Mexico's Federal Investigation Agency (Agencia Federal de Investigación or by its initials in Spanish AFI), and creates a new police investigative arm known as the Federal Ministerial Police (Policía Federal Ministerial). In accordance with the new law, new coordination procedures are established with the PGR, and more concrete standards will apply to confront criminal activity in a more efficient manner. The law establishes that the Federal Ministerial Police, which will function as a complementary support agency to the Federal Attorney General's Office, as well as the police departments of the Federal District and various state and municipal governments in Mexico. In addition, the new law creates the position of Ministerial Official (Oficial Ministerial) of the PGR, who will support the Public Ministry and implement recruiting and retention policies for agents of the Federal Ministerial Police. The new law also establishes its own obligations, implementation and sanctions regimes in order to be properly enforced. The new law seeks to create evaluation processes to increase trust within the ranks of federal police officials and subjects agents to background, medical and psychological examinations
