Well, it may be tough to sue them for a clerical error, and getting an attorney to take the case might be tough. Three days in custody based on the warrant is not likely to get too many attorneys in the area excited. The payout is just not likely to be there.
What court issued the warrant? You said the court hadn't existed in a long time?? I am not aware of any Superior Courts that have ceased to exist.
Your custody was lawful due to the warrant. So there is no false imprisonment action there. If there is any action at all it MIGHT be had against the court that originally issued the warrant if it should have been withdrawn. But unless the warrant was knowingly entered in even if it was not valid, or knowingly served when it was known to be invalid on its face, I don't see any action.
