A Castle Rock man’s claim that a Denver bakery discriminated against him when it wouldn’t place a gay slur on a cake he was ordering has been rejected by the Colorado Department of Regulatory Agencies.

In a decision letter to William Jack sent on March 24, the Agency’s Civil Rights Division said Azucar Bakery, 1886 S. Broadway, was within its rights when, in March 2014, it refused to bake him a Bible-shaped cake with hateful words about gays that he wanted written on the cake. According to the bakery, Jack also wanted the cake to have two men holding hands and an X on top of them.

According to the Associated Press, Marjorie Silva, the owner of the bakery, said she would make the cake, but declined to write Jack’s suggested messages on the cake, telling him she would give him icing and a pastry bag so he could write the words himself.

Silva said the customer didn’t want that.

An investigation was launched after Jack filed his claim of discrimination, which said he was denied service because he’s a Christian. In the letter to Jack, the Civil Rights Division said there was “insufficient evidence to support (Jack’s) claims.”

Reached on Friday, a spokeswoman for the division said via an email to The Post that it was not “at liberty to verify a case, provide comments and cannot legally provide or confirm information or documentation, records and correspondence related to Colorado Civil Rights Division cases.”

A telephone message to Silva was not returned on Friday.

In a response issued Friday, the Anti-Defamation League applauded the decision by the Civil Rights Division.

“ADL supports our state’s anti-discrimination laws that promote an inclusive and respectful Colorado,” the group said in a release.
