The Supreme Court of the United States has ruled that a federal law barring people with domestic violence restraining orders from owning firearms is unconstitutional.

The decision came on Tuesday in a 5-4 ruling, with Chief Justice John Roberts joining the four liberal justices in the majority. The law, which was passed in 1996, was intended to prevent those with a history of domestic violence from owning guns.

The case was brought by a woman in Massachusetts who had been the subject of a restraining order in the past. She argued that the law was an unconstitutional violation of her Second Amendment rights.

The majority opinion, written by Justice Brett Kavanaugh, held that the law was overly broad and violated the Second Amendment. The opinion stated that the law “sweeps too broadly in that it encompasses individuals who have never been dangerous and are not likely to become so.”

The decision is a major victory for gun rights advocates, who have long argued that the law was overly restrictive and violated the Second Amendment.

The ruling is likely to have a major impact on gun laws across the country, as many states have passed similar laws that could now be challenged in court.
