"The Investigating Minister granted the suspension requested by the INE with respect to all the challenged articles of the Decree so that things remain in the state in which they are today and the provisions in force before the respective reform apply," the highest court said in a Friday statement.
The supreme court emphasized that defendants in the lawsuit - the Mexican Congress and the federal executive - must submit their response to the INE lawsuit within the statutory period.
According to the high court, this case concerns "a possible violation of the political and electoral rights of citizens."
Mexican President Andres Manuel Lopez Obrador has repeatedly said that the current electoral system in the country is conducive to voter fraud, which he claimed took place in 2006 during his unsuccessful first run for presidency. The opposition has, in turn, said that the electoral reform violates the constitution and might threaten the holding of the presidential election in 2024.
