Two weeks of this crap Lee? Having been the plaintiff on a completely dissimilar case a couple years ago and knowing the stress it put me though, I can only start imagine how you and your wife feel.
Yeah, I would have gone with Jude's suggestion, but I'm not privy to all the ins and outs of your situation. I probably would have added a PI. Nor do I know if civil action is possible in that country against the accuser ex post facto...sometimes just the impression is enuf to make the accuser back down, let alone the school ("You do realize, when this is done, we're going to switch tables, we'll sue your nasty ass and you'll lose"). Short of that, having done your own homework (unintentional pun), it sounds like you're indeed taking some of your own power back.
Man, if it's not one thing it's another with this school.
