Bedecked in fondant and flowers, modern wedding cakes are the centerpiece of the marriage feast — an edible form of art. But are they also an expression of free speech?That is the question the Supreme Court will consider this fall when it hears the case of a Colorado baker who refused to make a custom wedding cake for a gay couple because he said it would violate his religious beliefs."You'd think cake would be apolitical, and yet here we are," muses baker Catherine George of Catherine George Cakes.She was among the Washington, D.C.-area pastry chefs who crafted 18 elaborate tiered wedding cakes to show their support for marriage equality. Their creations were on display Tuesday night at the sixth annual Chefs for Equality in D.C., a fundraiser hosted by the Human Rights Campaign. Some 140 chefs, pastry chefs and mixologists participated in this year's event. The theme: "Who Can Resist?"George said her cake — three-tiered and adorned with white fondant molding and columns meant to echo the neoclassical architecture of the Supreme Court building — was definitely intended as a political statement."I wanted to reference the Supreme Court case that's coming up," George says. "Which is funny, because the idea of cakes as art is part of that."She adds: "[I] strongly believe that gay people shouldn't be discriminated against when buying their wedding cake."Public accommodation laws in Colorado and elsewhere are designed to prevent discrimination by businesses that interact with the public. Five years ago, David Mullins and Charlie Craig asked Colorado baker Jack Phillips to make them a custom wedding cake. Phillips refused, saying he didn't want to be compelled to use his artistic talents — his cake creativity — to celebrate an event that violated his deeply held religious beliefs. So Mullins and Craig filed civil rights charges against the baker.The Justice Department, under President Trump,is backing the baker. In a brief filed with the court this month, it argues that the wedding cake case is at heart about the First Amendment and the right to free expression. Acting Solicitor General Jeffrey Wall wrote:
