Not infrequently Antonin Scalia lights up the Supreme Court with a lightning bolt of common sense. He did it again last week during oral arguments in Lawrence v. Texas.

This is the case that in determining whether homosexual behavior is a "right" may explode the foundation of law.

Famed Harvard lawyer Laurence Tribe wrote the brief submitted in the case by the American Civil Liberties Union. "Americans," he said, "have a fundamental right to be free from government regulation of consensual sexual conduct in the home."

Paul Smith, attorney for petitioners John Lawrence and Tyron Garner -- who were fined $200 in Houston for activities I will not describe here -- restated the proposition in his own brief. "Among the liberties protected by the Constitution," he said, "is the right of an adult to make choices about whether and in what manner to engage in private consensual sexual intimacy with another adult, including one of the same sex."

Some may wonder why this issue is arriving only now in the Court. Didn't we settle this long ago -- like, say, in a Woodstock mud pit? Isn't anything goes sexuality official Baby Boom doctrine?

We certainly don't want police in our bedrooms, do we?

Well, as lawyer Smith discovered, Justice Scalia missed all that rot.

The lightning bolt of Scalia's common sense crashed down on Smith as he was explaining that the problem with the Texas law banning homosexual conduct is that it represents an effort by the majority to impose their morality on the minority.

"But society always . . . makes these moral judgments," said Scalia. "Why is this different from bigamy?"

Indeed, if people have a "fundamental right" to "consensual sexual conduct in the home," why can't a man take two wives? Why not three? Why can't everybody pick the conglomeration of consensual partners that suits their peculiar appetite? As long as it's done "in the home," not in the street, it's a fundamental right. Right?

Wrong, said lawyer Smith.
