Going forward, Mexican voters will now elect judges at every level, dramatically restructuring the third branch of government.

Mexico’s Senate has voted to overhaul the country’s judiciary, clearing the biggest hurdle for a controversial constitutional revision that will make all judges stand for election.

Mexico’s highly contested judicial reform went into effect Sunday. In recent weeks, judges and other court workers have launched a wave of protests against the judicial overhaul, which will allow for the election of judges by popular vote.

Mexico's judicial reform has triggered investor concerns about uncertainty over the rule of law and the strength of the government's institutions, yet with the reform now priced in, some analysts argue there may be buying opportunities forming.
