Zachary C. Larsen

Senior Attorney

Zachary C. Larsen has litigated some of the most significant cases in Michigan during the past decade, including representing the State and its officials in the Flint water litigation, successfully defending against a Headlee Amendment claim and Administrative Procedures Act challenge to the $2.5 billion regulatory overhaul of Michigan’s lead and copper rule, and helping to save the treasury $1.6 billion in claimed refunds in 50 consolidated business tax cases brought by out-of-state corporations under the Multistate Tax Compact. 

Zach served for eight years as an assistant attorney general on issues of environmental, tax, and administrative law. He has handled cases at all levels of both the state and federal judiciary—from presenting evidence at hearings in trial courts and administrative tribunals to arguing at the Michigan Supreme Court and U.S. Court of Appeals for the Sixth Circuit. Because of his litigation success, legal writing ability, and skilled oral advocacy in handling appeals, Zach was awarded the Attorney General’s “Excellence in Appellate Advocacy” award.

In his environmental law practice, Zach has been responsible for a wide variety of cases under Part 31 (water quality), Part 55 (air quality), Part 115 (waste management), Part 201 (remediation), Part 213 (underground storage tanks), Part 301 (inland lakes and streams), and Part 303 (wetlands) of Michigan’s Natural Resources and Environmental Protection Act, MCL 324.101 et seq. He has achieved such victories for his clients as obtaining one of the largest wetlands civil fines in state history and negotiating a multimillion-dollar resolution to a nuisance odor dispute. He has also litigated citizen suits under the Clean Water Act, the Safe Drinking Water Act, and CERCLA and can advise clients on their obligations and rights under federal environmental law.

While representing the Michigan Department of Treasury, Zach addressed problems ranging from manufacturer’s claims of exemption and arguments over what constitutes “tangible personal property” under the General Sales Tax Act and the Use Tax Act to multistate tax apportionment and certificated credits under Michigan’s various business taxes. He was also routinely tasked with disputes over the tax implications of technology, such as cloud computing, computer software, telecommunications, patented processes, and electrical transmission and distribution.

Zach also spent years working as a research attorney advising judges and understands how judges think. He can help you craft your best arguments and assemble your case to maximize your likely success. And his years of state government experience can help you to navigate your controversy against a state agency.
