The owners of a Colorado bakery could face up to a year in prison for refusing to make a cake for a gay couple. Dave Mullins, 28, and Daniel Craig, 33, filed a discrimination complaint against Jack Phillips, one of the owners of Masterpiece Cakeshop, for denying them a cake for their Massachusetts wedding.

“Religious freedom is a fundamental right in America and it’s something that we champion at the ACLU,” said Mark Silverstein, the legal director of the group in Colorado, which filed the complaint last year on behalf of Mullins and Craig. “We are all entitled to our religious beliefs and we fight for that. But someone’s personal religious beliefs don’t justify breaking the law by discriminating against others in the public sphere.”
