Legal Question in Administrative Law in California

Were you charged in a criminal proceeding, or sued in a civil action? Did the wrongful accusation and the ensuing trial cause you significant harm to your reputation or finances? Going after someone who has accused you falsely may or my not be worth the time and expense, depending upon a number of factors not mentioned in your brief question. I'd say offhand that maybe 3/4 of the time "suing back" is not worthwhile, and maybe 1/4 of the time it is, but so much depends upon additional facts including how deep your pockets are and to what extent emotional satisfaction is important to you rather than getting money damages.
