The Office of the Attorney General (FGR) confirmed that an ongoing investigation is underway Maria Amparo Casaracademic and current president of the organization Mexicans against corruption and impunity (MCCI), for the possible crime of unauthorized use of authority to receive a lifelong pension Mexican petroleum (Pemex).
However, the Federal Justice Authority states that this investigation is not new, as it has been in development since September 2025:
“Concerning the information that has emerged about an investigation against the leader of a civil association, @FGRMexico indicates that the Federal Ministry of Public Affairs (MPF) is analyzing the investigation in detail to verify whether it was integrated in accordance with the law as soon as it was initiated in September and not recently, as some versions have incorrectly stated” (sic), reads the publication.
Almost at the end of the publication it is also said that the Marquez Padilla case “Amparo Casar is currently under investigation” is therefore “carried out outside the legal framework without prejudice of any kind”.
The original events occurred in 2004: Cesar Marquez Padillathe intellectual’s then husband, joined Pemex on June 1 of the same year and died on October 7, 2004 after a fall from the 12th floor of Building A of the Pemex headquarters. Then. the reports of the former Attorney General’s Office of the Federal District (PGJDF) classified the case as suicide at the time.
Twelve days later, on October 19th, the payment was made pension Post-mortem and Casar has been receiving this benefit since January 2005.
In 2024 the conflict escalated: Pemex suspended the Pension payment and the controversy reached the court. A federal judge ordered the provisional reactivation of the payment because he assumed that as long as there was no clear order to the contrary, the Entitlement to pension had to be retained, which forced the oil company to temporarily reintroduce it. The dispute led to civil and administrative proceedings and now to criminal path.

Now the FGR alleges that Casar – and two of his children are mentioned in some notes – may have intervened or encouraged irregular procedures to obtain or maintain the payment, which is why the criminal investigation was launched and hearings were scheduled on the allegation.
The case was also framed in the political confrontation between the Government of Mexico as well as personalities and organizations that criticize the administrations of the self-proclaimed Fourth transformation (4T). Casar and MCCI reportedly reported political persecution; The file is now also the subject of international reporting and media positioning, in which both the legality of the pension and the possibility of criminal prosecution are discussed.
To date, there are several procedural fronts: the civil/administrative issue of the validity of pension entitlement, the commute and the recent criminal conviction. In this sense, various journalistic sources report that Casar was summoned to a hearing at the Reclusorio Oriente to respond to the accusation.

The file continues to be processed and the case needs to be legally resolved on the basis of documents, administrative and expert evidence. Depending on the outcome of the criminal investigation and the jurisdiction examining the matter, the allegation could be confirmed or rejected.
