A baker from Colorado who refused to bake a cake for trans customer Autumn Scardina is counter-suing after the Supreme Court ruled that he had discriminated against Scardina.

Scardina was refused the baker’s service when she asked him to bake her a cake celebrating her birthday and the first anniversary of her gender transition.

The baker, Jack Philips, filed the Colorado Civil Rights Commission (CCRC) arguing that Colorado disrespected his religious views and that he had been treated with hostility.

Philips is being represented by the Christian lobbying group Alliance Defencing Freedom, which previously supported him in a lawsuit at the Supreme Court when he refused to bake a cake for a gay couple in 2016.

“At this point, he’s just a guy who is trying to get back to life,” Jim Campbell, an attorney for the Christian non-profit law firm Alliance Defending Freedom, told ABC.

“The problem is the state of Colorado won’t let him.”

In August, Scardina complained to the CCRC, alleging that she had been discriminated against on the basis of her gender identity, reports ThinkProgress.

“The woman on the phone,” she wrote in the filing, “did not object to my request for a birthday cake until I told her I was celebrating my transition from male to female.

“I believe that other people who request birthday cakes get to select the colour and theme of the cake.”

Phillips, meanwhile, filed a countersuit, writing that he does not want to “promote the idea that a person’s sex is anything other than an immutable God-given biological reality.”

In the case of his refusal to bake a cake for gay couple David Millins and Charlie Craig, the US Supreme Court ruled in favour of Philips.

In a court ruling, 7-2 ruled in favour of Masterpiece Cakeshop, a decision which was met by backlash from many in the LGBT+ community.
