What happens to any person or business who doesn't pay court ordered damages?
Bother it all. I'll tell you since no one knows. The order of the Labor Commissioner will be entered as an order of the court. The court can put a lien on all revenues from the business including putting a Marshal's "keeper" on the till or attaching the business bank account.
Since the gays were so enthusiastic and put these people out of business through their threats, there's no till and no bank account. The judgment will lay around for ten years. The couple can go back to court and have it renewed or it will just die.
