The case was brought by the Wisconsin Institute for Law & Liberty (WILL) on behalf of the Brown County Taxpayers Association and Citizens Defending Liberty. At the center of the dispute is whether the Wisconsin Legislature had the authority to authorize online sports betting under the state constitution. Speaking about the legal theory behind the challenge, Vebber argued that lawmakers cannot avoid constitutional limits simply by modifying statutory language. WILL further argues that any future compact amendments designed to implement the law would exceed the authority granted under state law. The lawsuit notes polling data from Marquette University Law School indicating that 64 percent of respondents oppose legalizing online sports betting in Wisconsin.
