A federal court in Mexico has ordered the reopening of the case of Mario Aburto Martínez, the man convicted of assassinating presidential candidate Luis Donaldo Colosio in 1984. The ruling mandates a reset of key legal proceedings and a renewed examination of Aburto's longstanding claims that he was tortured into confessing to the crime.
According to Mexico's La Silla Rota, the decision was issued by the Eighth Collegiate Criminal Court of the First Circuit, which determined that the case must be sent back to the original trial court. There, authorities are required to reassess the investigation, this time ensuring the full participation of all relevant parties.
The ruling overturns an earlier decision by Judge Paloma Xiomara González of the Second District Court in criminal matters, who had denied a legal appeal filed by Aburto's defense. That denial had upheld the findings of Mexico's Attorney General's Office, which concluded there was no evidence of torture during Aburto's arrest or transfer to Mexico City. That conclusion was formally communicated to the defendant in November 2023.
However, the appellate court found procedural flaws in that earlier process. Specifically, it ruled that individuals identified in the original investigation were not properly notified or allowed to participate, despite being legally entitled to do so. According to the three-judge panel, this omission violated due process, explains Infobae.
As a result, the court ordered the previous constitutional hearing to be voided and the legal process restarted. This opens the door for a fresh review of the torture allegations raised by Aburto.
The ruling stems from a legal challenge filed by Aburto's defense two years ago, which contested the decision by federal prosecutors to close the investigation into alleged mistreatment.
Prosecutors had argued there was insufficient evidence to support Aburto's claims. With the case now returning to the lower court, all parties involved must be formally reintegrated into the proceedings. This will allow the judge to reassess the available evidence and determine whether further investigation into the torture claims is warranted.
The reopening of the case represents a significant development in one of Mexico's most high-profile political assassinations. It signals that the judicial system will once again examine whether Aburto's rights were violated during the original investigation and whether those alleged violations had any impact on the outcome of the case.
