Good Points, Sir K. That restraining order bit, now that you mention it, is pretty sucky. A restraining order requires an affidavit though, IIRC. So, if you did get one for malicious reasons without a basis in fact, you'd be on the hook for perjury.
But, the real point is once you'd used the lie to get the restraining order, the restrainee (
) would have to hire a lawyer and go to court to fix it. That's often the real problem with the law. Folks come my way all the time who've been wronged for $500 or $5,000. I often explain as well as I can what kind of costs they are looking at and I really discourage anyone from pursuing any claim of less than 8-10K, depending on complexity of course.
Now, it's funny that the one client we will pursue small claims for is a huge national corp. We do 3-4K matters for them free of charge as a "thank you" for the $1-2 mil. matters they send to us. It's really true that you have to have money to make/keep money.
