Mexico’s Supreme Court has ruled against the automatic use of pretrial detention for certain crimes.

A 2019 decree mandated pretrial detention for tax fraud and other crimes. But, with an 8-3 vote Monday, the Supreme Court has ruled such automatic detention unconstitutional, arguing that the crimes don’t constitute a national security threat, according to a release from the court.

In a video published Tuesday on his Twitter account explaining the decision, Supreme Court President Arturo Zaldívar said that pretrial detention has long been abused in Mexico, impacting poor Mexicans who can’t afford quality legal representation the most.

But Mexico’s President Andrés Manuel López Obrador pushed back on the court’s decision during his morning press conference Tuesday, saying the ruling protects the corrupt.
