Holding: Because the Illegal Immigration Reform and Immigrant Responsibility Act burdens lawful activity on the basis of nothing more than past criminal activity, it was retroactive within the meaning of the Court’s precedents.
Judgment: Reversed and remanded, 6-3, in an opinion by Justice Ginsburg on March 28, 2012. Justice Scalia filed a dissenting opinion, joined by Justices Thomas and Alito.
