The Appellate Court for the Second District of Illinois recently expanded the reach of Illinois’ “common interest” doctrine in a professional negligence case against an insurance broker. In The Robert R. McCormick Foundation v. Arthur J. Gallagher Risk Management Services, Inc., 2018 IL App (2d) 170939 (July 20, 2018), the Court held that an insurance malpractice defendant was a de facto insurer and, thus, was able to secure access to documents that might otherwise be protected by the attorney-client privilege.
