On June 1, 2017, the Mandatory Initial Discovery Pilot Project (MIDP) took effect in the Northern District of Illinois. With only limited exceptions, the MIDP applies to all cases filed after June 1 and significantly impacts how cases in the Northern District of Illinois will proceed. In particular, cases in which defendants are seeking to dismiss a complaint or which involve large amounts of discovery will be most affected by the changes. Only a few types of cases are exempt from the MIDP: (a) cases exempted from initial disclosures by Rule 26(a)(1)(B); (b) cases transferred for consolidated administration by the Judicial Panel on Multidistrict Litigation; (c) patent cases; and (d) actions under the Private Securities Litigation Reform Act.
