Democrats and immigration advocates have previously criticized the “Migrant Protection Protocols” program, informally known as “Stay in Mexico.”

The Joe Biden administration on Friday appealed to the US Supreme Court with a request to block the decision of a judge (lower court), according to which the government should resume the controversial program under which tens of thousands of migrants were waiting for a decision on applications for refugee status in the U.S. on the territory of Mexico.

The U.S. Department of Justice has sent a petition to the Supreme Court to suspend the ruling of a court in Texas obliging the government to resume the Migrant Protection Protocols program, established by former President Donald Trump.

The ruling by U.S. District Judge Matthew Kacsmaryk “requires the government to resume without preparation an extensive and controversial immigration control program that has been officially suspended for seven months and has basically not been applied for almost nine months before,” acting U.S. Deputy Justice Secretary Brian Fletcher wrote in his justification to the Supreme Court, where conservative judges represent a majority (6-3), including three judges appointed by Trump.

The Ministry of Justice demands that the Supreme Court consider the petition immediately since the lower court’s decision takes effect on Saturday.

Democrats and immigration advocates have criticized the “Migrant Protection Protocols” program, informally known as “Stay in Mexico.” In their opinion, this program led to the fact that migrants, mainly from Central America, were in unsanitary conditions and were subjected to violence.

Arrests of migrants crossing the U.S.-Mexico border have reached a 20-year high in recent months, which Republicans attribute to Biden’s rejection of the “Migrant Protection Protocol” and other measures as part of Trump’s tough immigration policy.

The Biden administration has upheld a Trump-era order that allows the border service to expel migrants to Mexico without the possibility of seeking asylum in the United States.

Roberto Velasco, a senior official of the Mexican Ministry of Foreign Affairs responsible for relations with North America, said that Mexico has not yet received any notification from the U.S. government about the court’s decision.
