If you go to the district attorney, they will send you right backto the labor board. You could file a civil suit, but by the time you got to trial, the labor board will probably have taken care of the issue.
The only suit that might have some use would be for a writ of mandamus against the labor board. But, that would cost you as much as you're owed in legal fees.
So, you're stuck, I'm afraid. Can't think of any other avenue.
