Section 111.59 - Filing order with clerk of circuit court; period effective; retroactivity(1) In this section, "order" means the findings, decision and order of the arbitrator.(2) The arbitrator shall hand down his or her order within 30 days after his or her appointment; except that the parties may agree to extend, or the commission may for good cause extend the period for not to exceed an additional 30 days. If the arbitrators do not agree, then the decision of the majority shall constitute the order in the case. The arbitrator shall furnish to each of the parties and to the public service commission a copy of the 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 where the majority of the employees involved in the dispute resides.(3) Unless the order is reversed upon a petition for review filed pursuant to s. 111.60, the order, together with any other agreements that the parties may themselves have reached, shall become binding upon, and shall control the relationship between the parties from the date on which the order is filed with the clerk of the circuit court, as provided in sub. (2). The order shall continue effective for one year from that date, but the order may be changed by mutual consent or agreement of the parties. No order of the arbitrators 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 prior contract, to a date before the day on which the demands involved in the dispute were presented to the other party. The question whether or not new contract provisions or amendments to an existing contract are retroactive to the terminating date of a present contract, amendments or part thereof, shall be matter for collective bargaining or decision by the arbitrator.1993 a. 492; 1995 a. 225.
