Wouldn't have any idea, but I'll bet if you were audited, they'd be asking for it first thing.
Another - unrelated - question: If this is an act of civil disobedience, then the law is being broken. I have no problem with civil disobedience, as long as the person in question is willing to accept the consequences of the action. The law prohibiting gay marriage stands mute upon what the penalty is if the law is broken. What do you all think the penalty should be for having disobeyed this particular law?
