The Wisconsin Supreme Court says homeowners and store owners have the right to carry concealed weapons on their property for a lawful purpose under a constitutional amendment approved five years ago.
The court's ruling overturns the conviction of Milwaukee grocery store owner Munir Hamdan.
He was arrested in November 1999 when police found he was carrying a loaded gun in his pants pocket. His case is sent back to circuit court.
The high court also ruled the amendment guaranteeing the right to keep and bear arms does not overturn the state's 130-year-old ban on concealed weapons.
