Justice Antonin Scalia on Monday criticized the Supreme Court's recent rulings related to gay marriage.

The decisions, handed down in June, paved the way for same-sex marriages to resume in California and knocked down Section 3 of the Defense of Marriage Act (DOMA), a key provision which prohibited federal agencies from recognizing the legal marriages of gay and lesbian couples.

According to the AP, Scalia, who dissented with the majority opinion in the DOMA decision, said that Congress or the people – not the courts – should decide such issues.

“It's not up to the courts to invent new minorities that get special protections,” Scalia said during a gathering of more than 300 people sponsored by the Federalist Society.

The Federalist Society, which Scalia helped launch more than 30 years ago, seeks to reform the current American legal system to “say what the law is, not what it should be.” Members believe in a literal interpretation of the U.S. Constitution. Scalia, 77, is a self-described “textualist.”

As recently as June, Scalia publicly stated that the Constitution does not protect gay sex, saying that when judges find rights to “homosexual conduct” in the Constitution, they are in error.
