Mexico is holding its first ever judicial elections, which have stirred controversy and sowed confusion among voters as they struggle to understand a process set to transform the country’s court system.

Mexicans vote on Sunday in the country's first ever judicial elections, part of an overhaul of the nation's judiciary that critics warn could jeopardize the rule of law.

Mexicans will vote Sunday in judicial races for federal and state judges, a new practice that opponents fear will give the ruling party control of the judiciary and empower candidates with criminal ties.
