(

a) In cases that the board is required to determine the specific amount of a monetary remedy before issuing a final board order pursuant to

Section 1160.3, the determination shall be completed within one year of any board order finding unfair labor practice liability and directing the payment of a monetary remedy. (

b) In cases that a determination is made concerning the amount of a monetary remedy that is continuing to accrue as described in

Section 1160.3, and the board is required to determine any additional portion of the monetary remedy that has accrued after a final decision on employer liability, the board shall process to final board order a decision concerning the additional amount or amounts owed within one year of a final decision on employer liability, unless the board certifies to the parties that there is good cause for exceeding this time limit and provides a reasoned explanation for the assertion of good cause.

For purposes of this subdivision, “final decision on employer liability” means the date when a board order determining the specific amount of a monetary remedy owed by a respondent found to have engaged in an unfair labor practice becomes final because no appeal was sought or the date when a reviewing court dismisses an employer’s appeal or otherwise affirms the board’s order. (

c) If an employer’s liability and compliance proceedings are consolidated, the board shall act reasonably and without delay in reaching a final decision concerning the liability and amounts owed to workers, and shall explain to the parties any good cause for delay.
