A judge in the central Mexican state of Morelos hit a colleague during an argument over alleged irregularities in the appointment of acting judges, media reports said.
Justice Miguel Angel Falcon Vega struck the smaller Justice Ruben Jasso Diaz during a session of the Morelos Supreme Court, with the assault captured on a video that was posted on YouTube.
Other justices stepped in and stopped the attack, and Chief Justice Nadia Luz Maria Lara Chavez suspended the session.
The fight highlighted the split in the state's high court between supporters of Falcon Vega and Lara Chavez's backers over how justices are promoted and removed from their posts.
The Judiciary Council will investigate the incident and Jasso Diaz has the option to take legal action on his own, Lara Chavez said. EFE
