Lawsuit Seeks to Halt Launch of Tribal Online Sports Betting in Wisconsin

A conservative legal group has filed suit to block Wisconsin’s new tribal-only online sports betting law before it can launch, arguing the legislation violates the state constitution. The Wisconsin Institute for Law and Liberty (WILL) filed the challenge on August 5 in Waukesha County Circuit Court on behalf of the Brown County Taxpayers Association and Citizens Defending Liberty, naming Governor Tony Evers and members of his administration as defendants.

The law in question, enacted in April with bipartisan support, would let Wisconsin residents place mobile sports bets statewide as long as the server processing each wager sits on federally recognized tribal land. WILL argues that setup is little more than a workaround for a 1993 constitutional amendment that bars the legislature from authorizing new forms of gambling beyond a short list of exceptions: the state lottery, bingo, raffles, and pari-mutuel on-track wagering.

How the “Hub and Spoke” Model Works

Wisconsin’s approach mirrors the framework Florida used to bring the Seminole Tribe’s sports betting operation online. Under the law, a bet placed anywhere in the state is legally considered to have occurred wherever the tribal server that processes it is located — the “hub.” Bettors using their phones anywhere in Wisconsin are the “spokes.” Because the transaction is deemed to happen in Indian Country, state lawmakers argue it falls outside the constitutional gambling ban altogether.

WILL’s complaint rejects that reasoning outright. Attorneys for the group contend the legislature cannot accomplish indirectly what the constitution plainly forbids it from doing directly, and that redefining where a bet “occurs” doesn’t change the fact that a new form of gambling is being authorized statewide. The suit also challenges Evers’ authority to negotiate amended gaming compacts with Wisconsin’s tribes to implement the law, arguing he has no legal basis to sign off on activity the legislature itself couldn’t authorize.

An Equal Protection Argument, Too

Beyond the state constitutional claim, WILL is also raising a federal equal protection argument. The lawsuit says the law grants an exclusive statewide sports betting privilege to Wisconsin’s tribal nations based on tribal membership, which the plaintiffs frame as a race-based benefit under the Fourteenth Amendment. Evers spokesperson Britt Cudaback pushed back hard on that framing, calling WILL “a radical, right-wing entity” working to undermine tribal sovereignty and vowing the governor would fight the challenge.

Currently, bettors in Wisconsin can only place sports wagers in person at a tribal casino — there’s no legal way to bet from a phone or computer anywhere else in the state. The new law was designed to close that gap by extending mobile access statewide while keeping the entire operation under tribal control, similar to models several other states have used to expand betting through existing gaming compacts rather than opening the market to commercial operators. That process was already underway, with tribes and state officials negotiating updated compact terms that still need approval from the U.S. Department of the Interior before publication in the Federal Register.

WILL isn’t asking the court to unwind any existing tribal gaming compacts — the group has been clear the suit targets only the sports betting expansion, not tribal gaming broadly. But the requested relief is sweeping: a declaration that the law is unconstitutional, an order blocking Evers from moving forward with compact negotiations tied to sports betting, and an injunction preventing any state official from authorizing or administering mobile wagering anywhere in Wisconsin.

What Happens Next

None of WILL’s claims have been tested in court yet, and legal challenges like this one can take months to resolve. For bettors tracking when they’ll finally get legal mobile access in Wisconsin, the lawsuit introduces real uncertainty into a timeline that had otherwise been moving toward a launch. Until a judge rules, tribal casinos and state officials are left negotiating compact details for a law now facing a direct constitutional challenge — meaning anyone hoping to use a DraftKings promo code or similar offer from a national operator inside Wisconsin will likely be waiting a while longer regardless of how the case shakes out.
