A private religious high school can expel students it believes are lesbians because the school isn't covered by California civil rights laws, a state appeals court has ruled.

Relying on a 1998 state Supreme Court ruling that allowed the Boy Scouts to exclude gays and atheists, the Fourth District Court of Appeal in San Bernardino said California Lutheran High School is a social organization entitled to follow its own principles, not a business subject to state anti-discrimination laws.
