Representative Matters

He has represented and counseled more than 1,000 lawyers and law firms in civil liability, professional responsibility, risk management and disciplinary matters of all sorts. He has tried numerous cases in both federal and state court. His extensive background in complex commercial litigation and business torts provides an additional layer of substantive and procedural experience to meet the challenges of representing members of the legal profession and those upon whom they rely to provide insurance needs.

Mr. Browne joined Hinshaw & Culbertson LLP in August 1976. He is the firm’s General Counsel, and Partner-in-Charge of Hinshaw’s Chicago office. He is a former chair of the firm's professional liability group.

Mr. Browne has been recognized by his peers as a Leading Lawyer in the category of Personal Injury Defense Law: Professional Malpractice. In addition, he holds the AV® Peer Review Rating from Martindale-Hubbell, its highest rating for ethics and legal ability.

Mr. Browne teaches regularly for the Illinois Attorney Registration and Disciplinary Commission's Professional Responsibility Institute. He has lectured at several law schools, and is a former adjunct faculty member of The John Marshall Law School.

Representative Matters

Mr. Browne has been instrumental in establishing some of the basic parameters of legal malpractice law. As lead counsel, he has presented and argued imaginative principles of law that have resulted in several seminal decisions limiting the scope of a lawyer's civil liability, such as:

  • Goldstein v. Lustig, (1987) 154 Ill.App.3d 595, 507 N.E.2d 164 (establishing the Illinois rule that a lawyer is not liable to his client for mistakes in judgment).
  • Sheppard v. Krol, (1991) 218 Ill.App.3d 254, 578 N.E.2d 212 (holding that the plaintiff in an action for legal malpractice must plead and prove collectibility of any judgment he would have received in the underlying matter).
  • Buttitta v. Newell, (1988) 176 Ill.App.3d 880, 531 N.E.2d 956 (holding that the court will not lend its jurisdiction to any plaintiff whose action against a lawyer is founded on his own illegal or immoral acts of any sort, including the violation of a statute).
