The Supreme Court unanimously ruled against a Mexican green card holder challenging a deportation order on Monday.

The court’s ruling reversed a previous decision from the California-based U.S. Court of Appeals for the 9th Circuit. That court had held that Refugio Palomar-Santiago, a Mexican citizen deported for a 1998 DUI, was removed invalidly because of a subsequent Supreme Court decision finding that DUIs were not sufficient cause for removal.
