On November 28, 2012, the Supreme Court of Illinois entered an order adopting new Rule of Evidence 502 Attorney Client Privilege and Work Product; Limitations on Waiver and a second order amending Rule 201 General Discovery Provisions. The newly adopted rules address the inadvertent disclosure of privileged information and closely follow the Federal Rules addressing the same (FRE 502 & FRCP 26(b)(5)(B)). The rules will be effective January 1, 2013.
