In the Parker case, a 2-1 majority of the D.C. Circuit found that the DC city council's prohibition on handguns, and its ban on using any firearm for lawful self-defense, were violations of the Second Amendment. Today, the full Circuit denied the DC government's petition for a rehearing en banc.

The decision states: "Appellees' petition for rehearing en banc and the response thereto were circulated to the full court, and a vote was requested. Thereafter, a majority of the judges eligible to participate did not vote in favor of the petition. Upon consideration of the foregoing and appellees' Fed. R. App. P. 28(j) letter, it is ORDERED that the petition be denied."

A footnote to the order states: "Circuit Judges Randolph, Rogers, Tatel, and Garland would grant the petition for rehearing en banc." The following is the list of judges who voted on the petition, with affirmtive votes marked by an asterisk: "Ginsburg (Chief Judge), Sentelle, Henderson, Randolph,* Rogers,* Tatel,* Garland,* Brown, Griffith, and Kavanaugh."
