A new ruling by the U.S. Supreme Court could keep convicted sex offenders in prison even after their prison term expires.
On Monday, the high court upheld the 2006 Adam Walsh Child Protection Act, a measure which allows federal officials to hold inmates considered "sexually dangerous" indefinitely.
"The statute is a 'necessary and proper' means of exercising the federal authority that permits Congress to create federal criminal laws, to punish their violation, to imprison violators, to provide appropriately for those imprisoned and to maintain the security of those who are not imprisoned by who may be affected by the federal imprisonment of others," said Justice Stephen Breyer, writing the majority opinion.
Monday's ruling reverses an earlier decision by the 4th U.S. Circuit Court of Appeals in Richmond, Va. that said the statute was an overreach of congressional authority.
However, the court concluded that "the Constitution grants Congress legislative power sufficient to enact this law."
