The Biden administration must resume the “remain in Mexico” border policy first authorized under former President Donald Trump, a federal judge in Texas ruled Friday.

District Judge Matthew Kacsmaryk ordered officials to “enforce and implement” the policy, also known as the Migrant Protection Protocol. The court ruled that the administration violated federal procedural law when it first suspended the border policy back in January and later on when it fully rescinded the policy on June 1. The judge concluded that the policy must stay in place until it can be lawfully suspended.
