On February 27, 2018, the U.S. Supreme Court upheld key provisions of a 1996 federal statute that requires the detention of several classes of aliens (including convicted felons) while they contest the government’s efforts to deport them. The decision was a victory for WLF, which filed a brief in support of the statute on behalf of 31 Members of Congress, including the Chairmen of both the Senate and House Judiciary Committees. The Court agreed with WLF that the statute should be enforced as written, despite the claims of some critics that detaining criminal aliens indefinitely might violate their constitutional rights. The brief argued that Congress reasonably concluded that unless criminal aliens are detained while they await removal, there is too great a danger that they will abscond and/or commit new felonies. The Court also agreed with WLF that any constitutional challenges to the detention of aliens should proceed on an individualized basis, not as class actions.
