Zachary C. Larsen
Zachary Larsen represents companies in regulatory and environmental litigation and counsels industrial and agricultural businesses through compliance and permitting concerns.
From defending disaster-related lawsuits like the Flint Water and Edenville Dam class actions to filing industrywide administrative challenges or bringing remediation cost recovery actions, Zach has litigated some of Michigan’s largest environmental disputes. Zach served for eight years as an Assistant Attorney General for the State of Michigan, including in the Environment, Natural Resources, and Agriculture Division, so he knows what businesses can expect from a state enforcement proceeding and who to connect with to achieve a prompt resolution. Having successfully litigated billion-dollar claims and statewide regulatory challenges and negotiated multi-million-dollar consent judgments, Zach’s experience will help him solve a variety of matters.
Zach has litigated cases at all levels—from presenting evidence at trial courts and administrative tribunals to arguing before the Michigan Supreme Court and the U.S. Court of Appeals. Because he served for years advising judges, he understands how judges think and can assemble your case to maximize your likelihood of success.
Though Zach principally represents clients in environmental matters, he also draws on his years with the State of Michigan to help businesses navigate state tax and other regulatory compliance problems and has litigated significant business, sales, and use tax appeals, insurance receivership disputes, liquor control commission appeals, and Freedom of Information Act suits.
