- The Waukesha County judge will hear April 20 arguments on Wisconsin’s tribal betting law and expects to rule weeks later.
- Eight of Wisconsin’s 11 tribes are now parties defending the law and could seek to move the case to federal court.
- The plaintiffs will amend their complaint in December to invoke the anti-preferential-treatment amendment voters approved Nov. 3.
- Tribal apps still take bets only on tribal land, and FOX6 reported a statewide launch also waits on compact changes.
WAUKESHA, Wis. – The challenge to Wisconsin tribal sports betting now has a date in court: April 20, 2027. Circuit Judge J. Arthur Melvin fixed that hearing on Monday’s calendar and said his decision should land several weeks afterward. Monday’s order also brought eight tribal nations into the case as defendants alongside the state.
At issue is a state law meant to carry Wisconsin sports betting off tribal casino grounds and onto phones anywhere in the state. Two taxpayer groups, the Brown County Taxpayers Association and Citizens Defending Liberty, brought the Aug. 5 complaint in Waukesha County Circuit Court. Their complaint seeks a ruling that the law violates the constitution and an order stopping state officials from negotiating the compact amendments it depends on.
2025 Wisconsin Act 247, signed April 9, works through a single added paragraph in the statutory definition of a bet. A wager made on a phone or other electronic device by someone in Wisconsin falls outside that definition if two conditions hold. The server handling it must be “physically located on a federally recognized American Indian tribe’s Indian lands located in this state,” and the wager must run under a gaming compact “originally entered into prior to April 1, 1993,” the act says.
A federal detour remains possible. Melvin observed that the tribes could seek to shift the case to federal court, and none of their lawyers spoke to the point at Monday’s hearing.
The eight, as FOX6 listed them, are the Bad River Band of the Lake Superior Tribe of Chippewa Indians, Forest County Potawatomi Community, Ho-Chunk Nation, Menominee Indian Tribe of Wisconsin, Oneida Nation, Red Cliff Band of Lake Superior Chippewa Indians, Sokaogon Chippewa Community and Stockbridge-Munsee Community. The move went unopposed in the courtroom.
Only the complaint’s third claim invokes federal law. It casts the tribal-land requirement as a racial classification barred by the Fourteenth Amendment’s equal protection guarantee; the first two claims rest on the Wisconsin Constitution and state statute. A removal would take the April 20 date and the expected ruling with it, since a federal court sets its own calendar.
Both defenses are on file. Assistant Attorney General Colin Roth answered for the state in September, defending the law and asserting among the state’s defenses that the plaintiffs lack standing. The plaintiffs claim standing as taxpayers, pointing to a 2026 Wisconsin Supreme Court decision that lets taxpayers sue over spending under an unconstitutional statute. The tribes’ own 36-page filing, lodged in mid-October, asks Melvin to toss the complaint.
What Changes For Bettors
Wisconsin legalized online sports betting in April, yet a mobile wager still has to be placed on tribal land. The Oneida Casino sportsbook app accepts bets only on tribal grounds, and statewide wagering cannot start until the tribes settle an agreement with the state.
Three more steps stand between the law and a launch: Gov. Tony Evers has to renegotiate each tribe’s compact, federal sign-off on the amended compacts has to come through, and the lawsuit has to be resolved, which FOX6 said will not happen before spring.
A decision in the weeks after April 20 settles only the court question. The compact and federal approvals run on their own track, so legal sports betting in Wisconsin stays confined to tribal property until both are finished.
Amended Complaint Due
The plaintiffs plan to fold a new piece of the state constitution into the suit. Lucas Vebber of the Wisconsin Institute for Law & Liberty, the plaintiffs’ counsel, said his side will amend the complaint to invoke the amendment that bars preferential treatment by race or other protected class. The amendment passed Nov. 3 with 56% of the vote against 44%. That revised pleading carries a December deadline, and the two sides’ briefing then occupies February and March ahead of the April 20 arguments.
