Biography

Hon. Lynn Weaver-Boyle is a judge for the Cook County Circuit Court in Illinois. She was appointed to the Circuit Court by the Illinois Supreme Court in 2019 and was subsequently elected to the seat the following year. She filled the vacancy created by the retirement of Sebastian T. Patti (Ret.).


While on the bench, Weaver-Boyle has presided over the Traffic Division in the First Municipal District of the Municipal Department.


She received a B.A. from the University of Illinois at Urbana-Champaign in 1987. Weaver-Boyle then completed a J.D. at DePaul University College of Law in 1990.

At the firm, Weaver-Boyle represented clients in commercial litigation cases including issues involving contracts, torts, products liability, and construction defects. She also handled wildland fire litigation as lead counsel to individual plaintiffs and insurance companies.


She has taught trial advocacy as an adjunct professor at Northwestern University, Pritzker School of Law and served as an instructor for the Tel Aviv University LLM Program, where she instructed attorneys from Israel on trial advocacy techniques.
