Mexico's federal and state legislatures, all dominated by the ruling Morena party, have passed amendments to the Constitution that prohibit courts from challenging any Constitutional reforms.
In the past, courts in Mexico had been able to rule on whether a new reform violated existing precepts in the Constitution or international treaties that Mexico has signed.
But starting Friday, the changes will grant immunity from challenge to any amendment passed by two-thirds majorities in Congress and two-thirds of state legislatures.
