Jack Phillips, the Colorado baker whose decision to deny a cake to a gay couple landed him in the Supreme Court over the summer, was back in court Tuesday facing another allegation of LGBTQ discrimination.

In June, the Supreme Court partially upheld Phillips' choice to deny a wedding cake to a gay couple based on religious reasons. Now, Phillips' lawyers are suing in an effort to stop the state from taking action against the baker in another bias allegation.

Autumn Scardina, a transgender woman who is also a Denver attorney, said Phillips' bakery refused to make a cake for her in June 2017 to celebrate her transition from male to female. The request, which came weeks after the Supreme Court case involving Charlie Craig and David Mullins, was for a birthday cake colored pink on the inside and blue on the outside.

Phillips' lawyers from the Alliance Defending Freedom say Colorado is engaged in "unconstitutional bullying," The Gazette reports, and they are suing governor of Colorado John Hickenlooper's administration, the Division of Civil Rights and the Colorado Civil Rights Commission.

"At this point, he's just a guy who is trying to get back to life. The problem is the state of Colorado won't let him," Jim Campbell, an attorney for the Alliance Defending Freedom, said after Tuesday's hearing.
