On December 5, the US Supreme court heard arguments in the case of Masterpiece Cakeshop, Ltd. v. Colorado Civil Rights Commission. This case gives the newly minted Trump majority an opening to rethink public accommodations law. Currently, 45 states have laws that prohibit discrimination by businesses offering public accommodations: loosely, those offering goods or services to the general public. (The federal government claims some scope for jurisdiction under the interstate commerce clause.) These laws have always been controversial. Most recently, evangelical Christians have been arguing that these laws are too broad. The court has a chance to narrow the scope of public accommodation laws: prohibiting discrimination only in more narrowly defined range of essential accommodations.
