Mexico's controversial judicial reform requiring direct election of judges and magistrates emerged mostly unscathed on Tuesday from a Supreme Court vote on whether it violated the country's constitution.

Mexico’s Supreme Court has dismissed a proposal to reduce the scope of a contentious judicial overhaul making all judges stand for election.

Eight of 11 justices on Mexico’s Supreme Court have resigned and declined to participate in an election for the court scheduled for June, the court said on Wednesday.

Mexico's Supreme Court began debating the constitutionality of a controversial judicial overhaul on Tuesday, nearly two months after lawmakers passed the reform that would require the election of all judges over the next few years.

More resignations are expected to follow, along with a pending ruling on the validity of the reform, setting the stage for a possible constitutional battle.
