WASHINGTON — The U.S. Supreme Court on Tuesday heard arguments in a Colorado case about a same sex-wedding cake that ultimately could determine where the legal system draws the line between discrimination and religious freedom.

The legal fight stems from the refusal of Lakewood baker Jack Phillips in 2012 to make a wedding cake for fiancés Charlie Craig and David Mullins. Phillips argues he shouldn't be compelled to violate his religious beliefs by creating a custom dessert for the couple; they argue they are being discriminated against because of their sexual orientation, which is protected by Colorado law.

During the 90-minute hearing, all eyes in the crowded courtroom were on Justice Anthony Kennedy — widely believed to be the swing vote on the ideologically divided court.

Kennedy wrote the majority opinion in the 2015 case Obergefell vs. Hodges that legalized same-sex marriage, but the Ronald Reagan appointee previously has lent a sympathetic ear to arguments of religion and freedom of expression.

He had tough questions and comments for both sides.

Kennedy posed a question to Phillips' attorneys: If the baker's cakes were truly expressive and an extension of his First Amendment rights, would that make it OK for him to refuse to sell any of his cakes – and not just a custom one?


Kennedy also wondered whether the case could give a rise to a national movement to deny wedding cakes to same-sex couples.

“If you prevail, could the baker put a sign in his window, ‘We do not bake cakes for gay weddings'?" he asked.

But Kennedy also questioned whether the Colorado Civil Rights Commission took appropriate action when it disciplined Phillips for not serving Craig and Mullins.

"It seems to me that the state in its position here has been neither tolerant nor respectful of Mr. Phillips' religious beliefs," he said.

If there is one area where both sides agree, it's that the stakes in this high-court confrontation are huge and the court's eventual ruling — expected by next summer — could have far-reaching implications.

A victory for Phillips would open the door for more businesses to use religion and expression as an excuse for discrimination, argued David Cole of the American Civil Liberties Union.

“We don't doubt the sincerity of Mr. Phillips' convictions. But to accept his argument leads to unacceptable consequences,” Cole said. “A bakery could refuse to sell a birthday cake to a black family if it objected to celebrating black lives. A corporate photography studio could refuse to take pictures of female CEOs if it believed that a woman's place is in the home.”

But attorneys on the side of the Lakewood baker countered that the First Amendment rights of creative professionals were the real issue for the court.

"They believe that they can compel speech, of filmmakers, oil painters, and graphic designers in all kinds of context," said Kristen Waggoner, of Alliance Defending Freedom, in response to the arguments of the ACLU and its allies.

One vexing issue for the nine-member court was defining which professions were expressive and should be protected by the First Amendment. Compounding that question was whether there were differences even within an industry or even one shop — say, between a sheet cake and a carefully crafted wedding dessert.

"What is the line? How would you have this court draw the line?" asked Justice Neil Gorsuch, a Colorado native and the Supreme Court's newest member.

Noel Francisco, the U.S. solicitor general for the Trump administration, took the side of the baker and pointed to the cost as one clue.

"People pay very high prices for these highly sculpted cakes, not because they taste good, but because of their artistic qualities," he said.

In another exchange — between Waggoner and Justice Elena Kagan — the expressive rights of hairstyling and makeup were compared to those of a baker.

"Why is there no speech in creating a wonderful hairdo?" Kagan asked.

“The makeup artist may again, be using creativity and artistry, but when this court is looking at whether speech is involved, it asks the question of, is it communicating something, and is it analogous to other protected forms of speech?” Waggoner answered.

Said Kagan in response: “Because, you know, a makeup artist, I think, might feel exactly as your client does, that they're doing something that's of great aesthetic importance” to an event like a wedding.

“There's a lot of skill and artistic vision that goes into making somebody look beautiful. And why wouldn't that person or the hairstylist — why wouldn't that also count?” she added.

The Tuesday morning hearing was the latest chapter in a legal battle that dates to 2012, when Craig and Mullins went into Masterpiece Cakeshop ahead of their nuptials.
