It used to be ilegal to revoke a liquor license because of "patron's status as homosexuals"

My grandfather, J. Bruce Fratis,  argued this case which held that patron's status as homosexuals, without more, did not constitute good cause for suspension or revocation of a liquor license under Cal. Bus. & Prof. Code § 24200 (e) or Cal. Con. Art. 20 §22, and that Cal. Bus. & Prof. Code § 24200 (e), which required only a showing of patronage by homosexuals, was therefore unconstitutional.
