The Supreme Court overturned a controversial stun gun ban on Monday, even as it allowed the Obama administration to block firearms from government buildings.
In the first case, the justices unanimously upended a Massachusetts stun gun ban, calling it unconstitutional.
"While less popular than handguns, stun guns are widely owned and accepted as a legitimate means of self-defense across the country,” Justice Samuel Alito wrote. "Massachusetts’ categorical ban of such weapons therefore violates the Second Amendment."
Massachusetts's stun gun ban came into question after a woman was arrested for carrying one in her pursue for protection against her ex-boyfriend. Police arrested her, and a state court upheld the ban, arguing that the Second Amendment was never intended to apply to stun guns.
But the Supreme Court disagreed and reversed that decision Monday. The Second Amendment applies to all firearms, “even those that were not in existence at the time of the founding,” the high court wrote.
The case will be sent back to the state court to be reheard.
But the Supreme Court declined to intervene in another case over a gun ban in government buildings.
The high court will let stand a U.S. Postal Service (USPS) regulation that prohibits customers — even those who hold concealed carry permits — from bringing guns to pick up their mail.
This represents a win for the Obama administration, which argued in favor of the ban.
