regulations adopted by a regional court interpreter employment relations committee pursuant to Section 71823 shall be processed as an unfair practice charge by the board. The initial determination as to whether the charge of unfair practice is justified and, if so, the appropriate remedy necessary to effectuate the purposes of this chapter, shall be a matter within the exclusive jurisdiction of the board, except that in an action to recover damages due to an unlawful strike, the board shall have no authority to award strike-preparation expenses as damages, and shall have no authority to award damages for costs, expenses, or revenue losses incurred during, or as a consequence of, an unlawful strike. The board shall apply and interpret unfair labor practices consistent with existing judicial interpretations of this chapter and subdivision (b) of Section 71826. The board shall not issue a complaint in respect of any charge based upon an alleged unfair practice occurring more than six months prior to the filing

of the charge, except that if the rules and regulations adopted by a regional court interpreter employment relations committee require exhaustion of a remedy prior to filing an unfair practice charge or the charging party chooses to exhaust a regional court interpreter employment relations committee’s remedy prior to filing an unfair practice charge, the six-month limitation set forth in this subdivision shall be tolled during such reasonable amount of time it takes the charging party to exhaust the remedy, but nothing herein shall require a charging party to exhaust a remedy when that remedy would be futile.
