Concluded Cases

Tankcraft v. OSHA

WILL sued the Biden administration in federal court, on behalf of two Wisconsin businesses, challenging the Occupational Safety and Health Administration’s (OSHA) sweeping new vaccine-or-test mandate for businesses with 100 or more employees. OSHA’s emergency rule, issued November 4, requires businesses of a certain size to require proof of vaccination or regular COVID-19 tests for their employees. Companies that do not comply face penalties of over $13,000 per violation, or over $136,000 for a willful violation.


WILL filed an original action with the Wisconsin Supreme Court urging a review of the authority of the Dane County public health officer to issue a new county-wide mask mandate.


WILL filed a lawsuit against Wisconsin DNR Secretary Preston Cole, the Wisconsin DNR, and the Wisconsin Natural Resources Board, for ignoring a state law requirement to schedule a wolf hunt season for winter 2021.


WILL filed a lawsuit in Polk County Circuit Court on behalf of three residents and taxpayers raising a straightforward argument: governors cannot seize emergency powers more than once to address the same crisis.
