Martin Morrissey

Attorney in Edwardsville, IL

Martin Morrissey touts a 37+ year trial attorney and legal counselor career. He cites early life lessons combined with a good deal of courtroom experience and skilled mentors in helping him develop careful judgment and talent for providing solutions to clients in insurance defense litigation.

Working on civil cases and appeals in personal injury defense, insurance coverage, and carrier conduct, Martin advises and defends the insureds when they get sued and advises and defends insurance companies and their employees when they draw complaints.

Guided by early lessons learned, he believes the plain truth is: sometimes you must fight; you have to choose the right fight; your opponent must know that you are willing to fight; most people hate to fight; often, the well-chosen fight benefits the many; and often, you have to lead. Another pivotal experience occurred while working as a groundsman for a central Illinois electric utility company. Martin experienced a fast and pitiless learning curve, noting a young man makes few mistakes when learning to assist other men working in the sky on electrical lines. You must get ahead of problems and strive to avoid an error.

Recognizing that no one is very interesting if he is defined entirely by his work, Martin has been happily married for 37+ years, blessed with two great kids and a grandson. An avid reader, he enjoys reading mainly history, religion, philosophy, and the occasional novel. Additionally, Martin averages a 12-mile run per week and considers himself an adequate fisherman.

  • Maple v. Gustafson, 151 Ill. 2d 445, 603 N.E.2d 508 (1992) re-affirmed for Illinois trial courts the different legal standards of review to apply to jury verdicts in deciding motions for new trials versus motions for judgment notwithstanding the verdict or directed verdicts. The Maple case remains one of the most cited decisions in civil trial practice in the State of Illinois.
  • Wakeford v. Rodehouse Restaurants of Missouri, Inc., 154 Ill. 2d 543, 610 N.E.2d 77 (1992) established the criteria for disclosure of experts and their opinions for civil practitioners in Illinois until Supreme Court Rule 220 was repealed and Rule 213 revised thereafter.
  • Jackson v. Seib, 372 Ill. App. 3d 1061, 866 N.E.2d 663 (5th Dist. 2007) was a central decision in the appellate courts concerning the relevancy and admissibility of post-accident vehicular photographs in vehicular negligence cases.
  • In Peach v. McGovern, 2019 IL 123156, 129 N.E.3d 1249, Marty was the primary author of the amicus brief presented by the Illinois Association of Defense Trial Counsel (IDC).
