Robert A. Levy doesn’t own a gun, but he is at the heart of a Second Amendment case that the Supreme Court agreed to hear last week.

Levy, a millionaire and lawyer with lots of Washington connections, used his money to finance a challenge to the District of Columbia statute that prohibits the ownership of handguns.

The 31-year-old statute also places restricts on the possession of other firearms, including a requirement that the guns in homes be unloaded.
