Should Wisconsin allow Native American tribes to offer sports betting?
Waukesha County Judge J. Arthur Melvin has scheduled oral arguments for April 20 in a suit brought by the Brown County Taxpayers Association challenging Act 247, which authorizes tribal sports betting. The judge also ruled Monday that several state tribes, including the Oneida Nation and Menominee Indian Tribe of Wisconsin, are parties to the lawsuit.
Why it matters
The suit argues Act 247 violates the state Constitution and its 1993 amendment authorizing certain forms of gambling, and that it singles out tribal members for a benefit based on race. The outcome could affect how sports betting is offered to Wisconsin residents.
The judge set a schedule for legal briefs to be filed, with oral arguments on April 20 in Waukesha County. The 1993 constitutional amendment at the center of the dispute authorized certain forms of gambling in the state.
