If you thought the Supreme Court was done hearing cases about desserts, they might not be. Aaron and Melissa Klein, owners of “Sweet Cakes by Melissa,” asked the Supreme Court Monday to reverse the state of Oregon’s decision that fined them more than $135,000, and drove them out of business, for refusing to create a government-approved message celebrating same-sex marriage.

In 2013, a same-sex couple requested a cake from the Kleins for their marriage celebration. When the Kleins refused citing their religious beliefs, the couple sued a year later. In 2015, the Kleins were fined. The state of Oregon’s Bureau of Labor and Industries found that Aaron and Melissa violated Oregon’s public accommodations statute. In addition to the $135,000 penalty for “emotional damages,” BOLI issued a gag order, preventing them from even talking about their actual beliefs. Eventually, the Kleins were forced to shut down their bakery. Aaron and Melissa appealed the BOLI ruling to the Oregon Court of Appeals in April 2016. The Oregon Court of Appeals reversed the gag order but otherwise upheld the decision of BOLI.

Attorneys for the Kleins, First Liberty Institute and Boyden Gray & Associates, filed a petition for writ of certiorari with the Supreme Court. In a statement, Kelly Shackelford, President and CEO of First Liberty, said, “Freedom of speech has always included the freedom not to speak the government’s message. This case can clarify whether speech is truly free if it is government mandated.”

If the Supreme Court agrees to hear the Kleins' case, it would be the first of its kind since Masterpiece Cakeshop, Ltd. v. Colorado Civil Rights Commission. The Supreme Court has long protected the right to differ. In Masterpiece, the court only reminded the state that government officials cannot be hostile to the free exercise of the religious beliefs of its citizens.

As then-Justice Anthony Kennedy said during oral arguments, “Tolerance is essential in a free society. And tolerance is most meaningful when it's mutual.”

If the Supreme Court were to take this case, it would not only provide some closure for the Kleins, but the court would have another opportunity to resolve the most critical issue the Masterpiece ruling left unresolved: whether the government can compel citizens to create a message contrary to their religious beliefs. While conservatives and religious liberty advocates saw Masterpiece as a win, it was a narrow win that raised more questions than it answered.
