The Supreme Court on Thursday required President Donald Trump’s administration to “facilitate” the return of a Maryland man mistakenly deported to El Salvador but stopped short of requiring the government to return him to the United States.

The ruling isn’t a final decision on the legal merits of the case, but it does reverse a judgment from a three-judge panel from the same U.S. Court of Appeals for the District of Columbia Circuit that had allowed the firings to go forward.
