Justice Sonia Sotomayor wrote the dissent in the 303 Creative case before the Supreme Court, a ruling issued Friday.

“Today is a sad day in American constitutional law and in the lives of LGBT people. The Supreme Court of the United States declares that a particular kind of business, though open to the public, has a constitutional right to refuse to serve members of a protected class. The Court does so for the first time in its history,” she wrote.

Justices Elena Kagan and Ketanji Brown Jackson joined in the dissent.
