SAN DIEGO (AP) undefined Two skeletons that rested undisturbed on a San Diego cliff top for nearly 10,000 years are at the center of a modern court battle.

The University of California, San Diego, had intended to transfer the skeletons of a man and woman to a American Indian tribe for traditional burial. But lawsuits are complicating the plan.

The bones were discovered in 1976 during an excavation at University House, the traditional La Jolla home of the UC San Diego chancellor. The university was preparing to hand over the bones to the local Kumeyaay tribe when three UC professors filed a lawsuit Monday in Northern California to block the transfer.

Margaret Schoeninger of UC San Diego, Robert Bettinger of UC Davis and Timothy White of UC Berkeley argue that the bones are precious research objects and there is no evidence that they are Native American remains.
