(a) Discovery shall proceed as in all other civil actions.(b) Whenever possible, the parties are encouraged to limit discovery to the development of the information necessary to facilitate a meaningful mediation conference. Upon entry of an Order of Referral to court-ordered mediation, discovery is deferred. The duty to supplement existing discovery continues throughout the mediation process. In the event the case is not resolved during the mediation process, upon transfer back to the trial judge, discovery may recommence.(c) All oral or written communications made throughout the mediation process shall be confidential, exempt from discovery and inadmissible as evidence in the underlying cause of action unless all parties agree otherwise in writing. Evidence with respect to settlement agreements shall be admissible in proceedings to enforce the settlement. Subject to the foregoing, the mediator may not disclose any information obtained during the mediation process.Ill. R. Cir. Ct. Dupage Cnty. 14.04
