An attorney who resigned from the Oklahoma State Department of Health filed a lawsuit Tuesday against her former state agency, claiming Oklahoma’s new medical marijuana regulations are unconstitutional.

Julia Ezell filed the lawsuit on behalf of Leslie Ann Collum, a registered nurse and owner of an Oklahoma City medical marijuana dispensary. Collum’s lawsuit has requested an injunction stopping enforcement of House Bill 2612, also known as the Unity Bill, which Gov. Kevin Stitt signed into law last week.

House Majority Floor Leader Jon Echols and Rep. Greg McCortney co-wrote the bill to provide regulations for use and sale of medical marijuana in Oklahoma.

The lawsuit names Interim Commissioner of Health Tom Bates, the Health Department and the State of Oklahoma as defendants. The Health Department declined to comment on pending litigation.
