Another thing to bear in mind, too, is the plaintiff's ability to pay your costs. So a judge awards you costs, and even legal fees - can the plaintiff afford to actually cough up? This is one of the problems with legal aid - someone who has no money can go after someone who does, with no financial risk to themselves, but the defendant may be forced to pay to defend a borderline-frivolous lawsuit. If it's ridiculously silly and a slam-dunk defense, maybe consider representing yourself, to avoid legal costs that will never be recouped.

On the other hand, if the plaintiff is paying his/her own legal expenses you can bet it won't get too far if it's that silly, and you'd have a fair chance of recouping costs, or collecting on a counter-suit.
