WASHINGTON — A federal appeals court is siding with the Washington Redskins against a group of American Indians who say the football team’s trademark is racially offensive.

The decision issued today by the U.S. Court of Appeals in Washington doesn’t address the main issue in the 17-year-old case of whether the trademark is racist. It upholds the lower court’s decision in favor of the football team on a legal technicality.

The court agreed that the seven Native Americans who challenged the trademark waited too long to sue over the trademark issued in 1967.

They initially won — the U.S. Patent and Trademark Office panel canceled the trademarks in 1999 — but they’ve suffered a series of defeats in the federal courts since then.

U.S. District Judge Colleen Kollar-Kotelly overturned that decision in 2003 in part because the suit was filed decades after the first Redskins trademark was issued. The U.S. Court of Appeals then sent the case back to Kollar-Kotelly, noting that the youngest of the plaintiffs was only 1-year-old in 1967 and therefore could not have taken legal action at the time.

Kollar-Kotelly issued a new ruling last summer that rejected that argument. She wrote that the youngest plaintiff turned 18 in 1984 and therefore waited almost eight years after coming of age to join the lawsuit.

The judge did not address whether the Redskins name is offensive or racist. She wrote that her decision was not based on the larger issue of “the appropriateness of Native American imagery for team names.”

A three-judge panel of the appeals court upheld that decision today.

The plaintiffs have a backup plan: A group of six American Indians ranging in age from 18 to 24 filed essentially the same lawsuit two years ago, but the new case has been on hold until this one was resolved.
