Michael Larsen brings 38 years of complex litigation and problem-solving experience to every case he undertakes. Utilizing a team specifically designed for the case at hand, Mr. Larsen's experience allows him to quickly identify the core issues and chart a path to resolution, whether by trial, arbitration, mediation or settlement.


With 38 years of complex litigation experience, there are few areas of the law that Michael L. Larsen has not encountered. As a very active trial lawyer and the former chairperson of Parsons Behle & Latimer’s litigation practice group, he has been involved in every aspect of dispute resolution from virtually every vantage point. His experience ranges from serving as litigation counsel for some of Utah’s largest and best-known companies to representing individuals impacted by devastating personal loss or tragedy; representing or monitoring national insurance carriers’ interests in high stakes commercial litigation to seeking to enforce insurance policies according to their terms; and representing multinational corporations uniquely qualifies him to understand all angles of many types of disputes from a two-person partnership dispute to the Deepwater Horizon oil spill disaster.

Successfully Represented Rio Tinto In Clean Air Lawsuit

Parsons Behle & Latimer attorneys successfully represented Rio Tinto Kennecott in a significant clean air lawsuit argued before a federal judge of the United States District Court, in Utah. On June 8, 2016, the ruling sided with Parsons’ arguments in support of Kennecott.

A coalition of environmental groups filed a citizen suit against Kennecott under the Clean Air Act seeking to significantly limit mining activity at Utah’s Bingham Canyon Mine.

The team, led by Michael A. Zody, successfully argued the cross motions for summary judgment in court. Senior litigation attorney Michael L. Larsen and environmental attorneys Michael A. Tomko and Jacob A. Santini, laid out key factual and legal arguments before the court. Federal Judge Robert Shelby determined that the State of Utah had granted Kennecott the necessary permits each time it planned to increase mine production and did not violate any laws.
