Nope. That wouldn't have been an issue, and you're confusing this case with a different one.
Maybe I'm confused. Are there two similar Colorado gay cake issues? The original issue that's going to the Supreme Court said:
"In July 2012, Craig and Mullins visited Masterpiece, a bakery in Lakewood, Colorado, and requested that Phillips design and create a cake to celebrate their same-sex wedding. Phillips declined, telling them that he does not create wedding cakes for same-sex weddings because of his religious beliefs, but advising Craig and Mullins that he would be happy to make and sell them any other baked goods." Court of Appeals No. 14CA1351
