Lawsuit Challenges Wisconsin Online Sports Betting Legality

A new lawsuit has been filed seeking to prevent the launch of online sports betting in Wisconsin. The suit alleges that the recently approved Act 247, which permits online sports wagering, violates both state and federal constitutional provisions.

What Happened

On August 5, the Wisconsin Institute for Law and Liberty (WILL) filed a lawsuit on behalf of the Brown County Taxpayers Association and Citizens Defending Liberty, aiming to halt online sports betting in Wisconsin before its implementation, according to fox6now.com. The lawsuit contends that Act 247, the bipartisan law authorizing online sports betting, is unconstitutional. Governor Tony Evers and tribal nations are reportedly defending the legislation (fox6now.com).

The legal challenge argues that Act 247 infringes upon a 1993 state constitutional amendment that prohibits the Legislature from authorizing gambling in any form, with specific exemptions for bingos, raffles, on-track betting, and the state lottery, as reported by fox6now.com. Furthermore, the lawsuit claims the law violates constitutional protections under the equal protection clause by exclusively allowing online sports betting on servers located on tribal lands, stating that it “provides a benefit to some – not all – based on, at bottom, race” (fox6now.com).

Key Details

• The lawsuit was filed by the Wisconsin Institute for Law and Liberty (WILL) on August 5, representing the Brown County Taxpayers Association and Citizens Defending Liberty (fox6now.com).
• Act 247, which was approved by the Wisconsin Legislature and Governor Tony Evers in April, allows for legalized online sports betting, requiring servers for online bets to be located on tribal lands (fox6now.com).
• The legal challenge cites a 1993 state constitutional amendment prohibiting the Legislature from authorizing most forms of gambling and alleges a violation of the equal protection clause of the U.S. Constitution (fox6now.com).
• Reportedly, 64% of Wisconsinites opposed the state legalizing online sports betting in a February Marquette Law School Poll (fox6now.com).
• Governor Tony Evers’ spokesperson, Britt Cudaback, stated that the governor intends to fight the new legal challenge and accused the law firm of attempting to undermine the sovereignty of Wisconsin’s Tribal Nations (fox6now.com).
• The Forest County Potawatomi Community stated that Act 247 does not violate any provisions of the U.S. Constitution, federal law, or the Wisconsin Constitution, referencing a 2006 Wisconsin Supreme Court ruling that allowed for the expansion of gaming through compact amendments (fox6now.com).

Why It Matters

This lawsuit introduces significant legal uncertainty into Wisconsin’s nascent online sports betting market. The outcome will have direct implications for the state’s ability to implement Act 247 and for the tribal nations involved in these new gaming agreements. The legal challenge, based on both state and federal constitutional grounds, could establish precedents for how online betting is regulated in states with similar constitutional restrictions on gambling or those seeking to expand tribal gaming compacts. The debate over the location of betting servers and its implications for equal protection highlights a complex intersection of gaming law, tribal sovereignty, and constitutional interpretation in regulated markets (fox6now.com).

The bipartisan nature of Act 247, as noted by fox6now.com, indicates a legislative consensus on enabling online sports betting, which is now being tested in the judicial system. The public sentiment, with 64% of Wisconsinites reportedly opposing state-legalized online sports betting according to a February Marquette Law School Poll, suggests a potential divergence between legislative action and public opinion (fox6now.com). The lawsuit’s focus on whether placing bets from anywhere in the state, processed on tribal servers, constitutes an expansion of gambling beyond tribal lands is a critical point of contention (fox6now.com).

What’s Next

Governor Tony Evers’ spokesperson, Britt Cudaback, indicated that the governor will contest the legal challenge (fox6now.com). Prior to the full launch of online sports betting, the governor needs to renegotiate agreements with the state’s 11 tribes, a process that has begun but can be protracted. Subsequent federal government approval is also required once deals are reached (fox6now.com).
