The National Collegiate Athletic Assn., despite the ruling of a California court, said it will press for drug testing even though tests probably violate athletes’ privacy.

In the meantime, NCAA lawyers prepared to appeal Wednesday’s ruling by Conrad Rushing, a Santa Clara County Superior Court judge, that declared the NCAA program unconstitutional.

The ruling applies only to Stanford, but it could be used as a precedent if other legal challenges are raised.

“The right to engage in NCAA competition is not a right guaranteed by the U.S. Constitution,” NCAA President Wilford S. Bailey said. “It’s a privilege. And if an individual wishes to compete in NCAA championship events, the individual must be prepared to comply with the rules established by the membership.”
