The Supreme Court of Justice of the Nation (SCJN) has unanimously ruled that Minister María Estela Ríos González is not disqualified from participating in discussions about how the Judicial Power of the Federation (PJF) will comply with an Inter-American Court of Human Rights ruling. This ruling mandates the Mexican state to declare unconstitutional the practices of arraigo and preventive detention that are often criticized for violating human rights. The decision was presented by the Court's president, Hugo Aguilar Ortiz, who emphasized that there were no concerns regarding Ríos' impartiality.

This outcome is significant in the context of ongoing debates surrounding human rights in Mexico, particularly concerning preventive detention, which has been a contentious issue. The SCJN's decision to allow Ríos' participation is seen as a step towards addressing the compliance with international human rights standards, as it gives a signal that no internal biases will impede the Court's commitment to justice. There is also an implication that the Court aims to uphold its credibility both domestically and internationally by clarifying its stance on the adherence to the Inter-American rulings.

This particular ruling comes on the heels of previous calls from legal and human rights sectors in Mexico for comprehensive reforms of detention practices. With Minister Ríos now able to participate in these discussions, it opens the door for potentially transformative changes to how preventive detention is approached in Mexico, fostering a judicial environment that aligns more closely with human rights principles as outlined by international law.
