"... when the defendant knew or should have known that the plaintiff’s spouse was married shall constitute proof of intentional interference with the plaintiff’s marriage. Damages awarded pursuant to this statute shall not exceed $500,000. This action shall be instituted within two years of the discovery of the adultery."
Maggie Gallagher is inspired by this proposed statute (from Minnesota, oddly enough). But what she really wants is not that you should be able to extract half a million dollars from the person who seduced your husband/wife. She wants a cause of action against websites that facilitate adultery.
