Background and Relevance of the Case

In a landmark decision, the Supreme Court of Justice of the Nation (SCJN) has ordered that an opinion from the United Nations (UN) regarding arbitrary detention be taken into account. This case revolves around an indigenous man who has been detained for over a decade following his arrest in 2012 on suspicion of marijuana possession.

The Detained Man’s Story

Following his violent arrest in 2012 for alleged marijuana possession, the man claimed to have been subjected to torture with the intention of incriminating himself for two separate homicides against tribal leaders. Although he was released regarding the first offense, he was immediately rearrested and has been held in preventive detention for over ten years due to ongoing criminal proceedings for the other two crimes.

The Role of the UN Group of Experts on Arbitrary Detention

In response to this situation, the detained man filed a complaint with the UN Group of Experts on Arbitrary Detention (GTDA). After reviewing the case, the GTDA issued Opinion 75/2018, classifying his detention as arbitrary and calling for his release along with reparative measures from the Mexican authorities. However, these recommendations were not followed by the Mexican government.

SCJN’s Ruling

The man then initiated an indirect habeas corpus lawsuit, which was dismissed by the District Court. This decision was appealed and eventually reviewed by the SCJN upon request from a former court minister. The ruling, approved by six votes against three, determined that the District Court’s reasoning was connected to the core of the matter, including the value of the GTDA’s opinion on arbitrary detention.

Implications of the SCJN’s Decision

The SCJN’s decision sets a precedent by stating that the non-binding nature of the GTDA opinion does not allow national authorities to automatically disregard such pronouncements. Instead, these opinions should be considered as relevant interpretative criteria to ensure effective justice.
