Christy Sports has asked a federal appeals court to rehear its case against a Utah ski resort. Christy alleges that Deer Valley ski complex in Utah violated antitrust laws by restricting Christy Sports from offering ski rentals and competing with a resort-run rental shop. The U.S. Court of Appeals for the 10th Circuit on Feb. 18 issued its decision in favor of the ski resort.

The decision by the 10th Circuit Court of Appeals affirmed a lower federal-court ruling that Deer Valley Resort Co. had the right to bar competing businesses from land it no longer owned but for which it still controlled the right of approval of tenants.

Christy Sport's new petition, according to the Denver Post, claims appellate judges failed to follow precedent established by the U.S. Supreme Court.

Christy Sports originally filed suit against Deer Valley in 2006 after the Park City resort barred the ski-rental company from the Deer Valley village after it had been there for 15 years. The resort offered ski rentals at the mountain's base, but the ritzier midmountain village had only Christy and another sports shop until 2005, when Deer Valley opened its own.

Christy Skis continues to rent skis at Deer Valley pending the outcome of the case and another lawsuit in Utah.
