The law, which prohibits discrimination on the basis of sexual orientation, is the same one at issue in the case of Colorado baker Jack Phillips that was decided in 2018 by the U.S. Supreme Court.
The high court said at the time that the Colorado Civil Rights Commission had acted with anti-religious bias against Phillips after he refused to bake a cake for two men who were getting married. But it did not rule on the larger issue of whether a business can invoke religious objections to refuse service to LGBTQ people.
The Arizona-based Alliance Defending Freedom represented Phillips and represents Smith.
