The Trump administration asked the Supreme Court to allow it to begin enforcing severe new restrictions on migrants who seek asylum protections after crossing the U.S.-Mexico border.

Under the joint rule issued by the Department of Justice and Department of Homeland Security last month, migrants arriving at the southern border are ineligible for asylum unless they have sought refugee status in one of the countries they traveled through first.

The new restrictions, which seek to curb the number of asylum claims made by migrants traveling through Central America, were swiftly challenged in federal court by four immigrant rights groups, and a federal district judge in San Francisco issued a nationwide injunction last month blocking the Trump administration from enforcing the rule.

But the 9th Circuit Court of Appeals narrowed the injunction this month to apply only within its circuit, which includes the border states of Arizona and California. Under the order, which gave the Trump administration a partial victory, federal immigration authorities appeared to be given the green light to enforce the asylum restrictions in New Mexico and Texas.

In his filing with the Supreme Court on Monday, Solicitor General Noel Francisco asked the justices to halt the order from U.S. District Judge Jon Tigar, appointed by former President Obama, while legal proceedings continue.

Francisco argued the order “frustrates the government’s strong interest in a well-functioning asylum system” and “undermines a coordinated effort by the Executive to curtail” the surge of migrants crossing the southern border illegally.

Additionally, the rule at issue “alleviates a crushing burden on the U.S. asylum system by prioritizing asylum seekers who most need asylum in the United States," Francisco said.

“The injunction prohibits the Executive Branch from implementing an interim final rule adopted to address an ongoing crisis at the southern border, with significant implications for ongoing diplomatic negotiations and foreign relations,” he told the Supreme Court.
