Illinois Discovery Closure and arbitration Order is a legal document issued by the Illinois court system that serves to close the discovery process in a civil lawsuit and to order the parties to proceed to arbitration. The document is typically issued after the parties have had an opportunity to exchange evidence and information during the discovery process. The order sets forth the terms and conditions for the arbitration and provides a timeline for its completion. There are two types of Illinois Discovery Closure and arbitration Order: (1) a mandatory order and (2) a voluntary order. A mandatory order is issued when the parties have been unable to reach an agreement on the discovery process or when the court determines that the discovery process should be terminated. A voluntary order is issued when both parties agree to proceed to arbitration. In either case, the order states that all discovery must be completed within the timeline set forth in the order. The order also requires the parties to submit their claims and defenses to the arbitrator and to abide by any decision rendered by the arbitrator.
