The California Supreme Court has ruled that physicians may not discriminate and withhold non-emergency medical care based upon their religious beliefs in violation of the California Unruh Civil Rights Act, which prohibits discrimination by businesses based on sexual orientation. In North Coast Women's Care Medical Group, Inc. et al. v. San Diego Superior Court, a lesbian, Guadalupe T. Benitez brought suit against the physician group and two individual doctors for refusing to provide intrauterine insemination using unfrozen semen from a friend to assist her obtaining pregnancy. This is a medical procedure in which a physician threads a catheter through a patient's cervix and inserts semen through the catheter into the patient's cervix. One of the physicians claims that her religious belief's in question have more to do with the patient being unmarried than a lesbian, but that is disputed by the plaintiff.
