The U.S. Supreme Court on Friday upheld a federal law that makes it a crime for people under domestic violence restraining orders to have guns.

The 8-1 ruling, authored by conservative Chief Justice John Roberts, overturned a lower court's decision striking down the 1994 law as a violation of the U.S. Constitution's Second Amendment right to "keep and bear arms."

"When an individual has been found by a court to pose a credible threat to the physical safety of another, that individual may be temporarily disarmed consistent with the Second Amendment," Chief Justice John Roberts wrote in the 8-1 opinion.
