Charlie Craig and Dave Mullins sought to hire Masterpiece Cakeshop of Lakewood, Colorado, to provide the cake for their same-sex wedding.  Masterpiece owner Jack Phillips declined, stating that his religious beliefs would not allow him to accommodate them.  Craig and Mullins filed a complaint with the Colorado Civil Rights Commission under Colorado’s Anti-Discrimination Act, which forbids businesses open to the public from discriminating on the basis of sexual orientation.  Phillips responded that his right to practice his religious beliefs took precedence.

The Commission ruled in favor of Craig and Mullins, and Colorado courts affirmed their decision primarily on the grounds that creating a custom cake was neither an expression of free speech nor an exercise of religious belief.  Phillips then appealed to the United States Supreme Court.
