U.S. Supreme Court to review legality of Trump's 'remain in Mexico' asylum policy

The U.S. Supreme Court on Monday agreed to decide the legality of one of President Donald Trump’s hardline immigration policies that has forced tens of thousands of migrants along the southern border to wait in Mexico, rather than entering the United States, while their asylum claims are processed.

The justices will hear a Trump administration appeal of a 2019 lower court ruling that found the policy likely violated federal immigration law. The program, called Migrant Protection Protocols, remains in effect because the Supreme Court in March put the lower court’s decision to block the policy on hold while the legal battle continues.

The Republican president has said the “remain in Mexico” policy, which took effect in January 2019, has reduced the flow of migrants from Central America into the United States. Restricting both illegal and legal immigration has been a central theme of Trump’s presidency. He has sought to reduce asylum claims through a series of policy and rule changes.

Immigration advocacy groups and 11 individual asylum seekers who fled violence in El Salvador, Guatemala and Honduras were returned to Mexico after entering the United States filed suit to challenge the legality of the policy.

The “remain in Mexico” policy, which represented a fundamental change to previous U.S. practice, is one of the steps Trump has taken to try to prevent large-scale migration from Central America and other countries across the U.S.-Mexican border. His administration has said allowing the thousands of asylum seekers across the border would swamp the U.S. immigration system and damage American relations with Mexico.

A federal judge blocked the program nationwide, saying that forcing these asylum applicants to wait in Mexico was contrary to the text of the Immigration and Nationality Act and violated treaty-based obligations to not send refugees back to the dangerous countries from which they came.
