One year ago today, the Supreme Court handed down its decision in District of Columbia et al. v. Heller. The decision affirmed the Second Amendment as protecting an individual right to keep and bear arms and invalidated the District of Columbia’s draconian gun control regime.

The case generated a storm of media attention. The Cato Institute filed an amicus brief, one of nearly four dozen in the case.

The Cato Institute held a forum for Brian Doherty’s book chronicling this victory for liberty, Gun Control on Trial: Inside the Supreme Court Battle Over the Second Amendment. The Heller case also figured prominently in Cato multimedia from Robert A. Levy and Clark Neily.

Heller did not settle all of the questions related to the right to keep and bear arms. The incorporation of the Second Amendment against state bans and regulations is currently being litigated across the country. A three-judge panel in the Court of Appeals for the Ninth Circuit held that the Second Amendment is incorporated against the states. The Seventh Circuit and Second Circuit disagreed. Supreme Court nominee Sonia Sotomayor was on the Second Circuit panel that declined to incorporate the Second Amendment, and Roger Pilon notes that this may play into her confirmation hearings. The circuit split on incorporation sets the stage for a further appeal to the Supreme Court, and Alan Gura and the National Rifle Association have both filed petitions for a writ of certiorari. Robert A. Levy discusses this in his recent Cato podcast.

It will be interesting to see what the next year brings for the Second Amendment.
