Ind. Code § 22-6-2-11
The board of arbitration shall hand down its findings, decision, and order (referred to in this section as its order) within sixty (60) days after its appointment; provided, however, that the governor may for good cause extend said period for not to exceed an additional sixty (60) days. If all three (3) members of the board do not agree, the order of the majority shall constitute the order of the board. The board shall furnish to each of the parties a copy of its order. A certified copy thereof shall be filed in the office of the clerk of the circuit court of the county wherein the dispute arose or in the office of the clerk of the circuit court of any county where the employer operates or maintains an office or place of business. Unless such order is reversed upon a petition for review filed pursuant to the provisions of section 12 of this chapter, such order, together with such agreements as the parties may themselves have reached, shall become binding upon and shall control the relationship between the parties from the date such order is filed with the clerk of the circuit court as aforesaid and shall continue effective for one (1) year from that date, but such order may be changed by mutual consent or agreement of the parties. No order of the board relating to wages or rates of pay shall be retroactive to a date before the date of the termination of any contract which may have existed between the parties, or, if there was no such contract, to a date before the day on which the governor appointed a conciliator in such dispute.
