Speaking at Princeton University, Scalia was asked by a gay student why he equates laws banning sodomy with those barring bestiality and murder.
"I don't think it's necessary, but I think it's effective," Scalia said, adding that legislative bodies can ban what they believe to be immoral.
Scalia has been giving speeches around the country to promote his new book, "Reading Law," and his lecture at Princeton comes just days after the court agreed to take on two cases that challenge the federal Defense of Marriage Act, which defines marriage as between a man and a woman.
Some in the audience who had come to hear Scalia speak about his book applauded but more of those who attended the lecture clapped at freshman Duncan Hosie's question.
