The lawsuit calls the laws “over burdensome and unnecessary regulations”, and seeks to have them invalidated, citing the Supremacy Clause in the Constitution. Specifically claiming that the Egg Products Inspection Act (EPIA), passed in 1970, supersedes Michigan’s law and establishes “‘uniformity of standards for eggs’ moving in interstate commerce.”

The transition to cage-free eggs in Michigan began back in November 2019, when Lt. Gov. Garlin Gilchrist stepped in for Gov. Whitmer and signed Public Act 132. Egg suppliers had until 2025 to comply with the new regulations for egg sales in the state. The laws were passed by a Republican-led legislature and passed with bipartisan support in both chambers.
