However, on April 21, 2005, the D.C. Court of Appeals affirmed the panel's rulings, dismissing the District's claims alleging the industry could be liable for distribution practices that fuel the illegal market. The Court again upheld the District's strict liability act and allowed the individuals plaintiffs' claims under that act to go forward, rejecting claims by the gun industry that the statute was unconstitutional under the Commerce and Due Process Clauses of the U.S. Constitution. The District also retains the right to recover medical costs paid to care for anyone injured by a gun covered by the strict liability act. The ruling will allow the claims by nine individual victims of gun violence to proceed toward trial against gun makers under the strict liability act.
On July 20, 2005, Defendants filed a petition for a writ of certiorari before the Supreme Court, asking the Court to overturn the D.C. Court of Appeals and strike down the District_s strict liability statute as unconstitutional, arguing that that the statute regulates out-of-state gun manufacturers in violation of the interstate commerce clause. But on October 3, 2005, the Supreme Court declined to review the decision, allowing the plaintiffs' claims under the strict liability at to go forward.
