SAN FRANCISCO — A Native American student wore an eagle feather that he considers sacred to his high school graduation ceremony after resolving a court fight with a California school district.

Christian Titman, clad in blue with his fellow graduates of Clovis High School, marched into the stadium at sunset Thursday, his long braid with the eagle feather attached came out one side of his cap while the traditional graduate’s tassel hung over the other side.

His presence — and the feather’s — at the ceremony came after a last-minute deal with the Clovis Unified School District, which sought to enforce the strict graduation dress code that had previously led it to deny stoles, leis, rosaries and necklaces on other students.

The 18-year-old is a member of the Pit River Tribe, which considers eagle feathers sacred and symbolic of a significant accomplishment, and he said the district was violating his rights to freedom of expression and religion under the California Constitution.

The case went to court before the sides agreed that Titman could wear the feather in his hair and attach it to his cap for the traditional tassel turn.

The American Civil Liberties Union, which represented Titman in the lawsuit, issued a statement Thursday night congratulating him on graduating and “proudly displaying and eagle feather.”

“His determination to advocate for what is right has inspired us all,” the ACLU said.

His mother, Renee Titman, did not immediately respond to phone messages left after the ceremony.
