Legal Showdown in Maine: Oxford Casino Challenges iGaming Expansion

Oxford Casino has filed suit against the Maine Gambling Control Unit, arguing that the state’s move to license online casino games only to the Wabanaki Nations creates an unlawful, race-based monopoly. The complaint, reported by the Portland Press Herald, asserts Equal Protection Clause violations under both the U.S. and Maine Constitutions and warns that commercial casinos could lose millions in revenue while employment at retail properties could be “drastically affected.” The suit adds, “Promoting iGaming through race-based preferences deals a gut-wrenching blow to Maine businesses like Oxford Casino that have heavily invested in the State and its people.”

Oxford is one of two commercial casinos in Maine.

How the tribal exclusivity unfolded

Lawmakers advanced Legislative Document 1164 to grant Maine’s four federally recognized tribes—Penobscot Nation, Passamaquoddy Tribe, Houlton Band of Maliseet Indians, and Mi’kmaq Nation—sole rights to offer online slots and table games statewide. The House approved the measure 85–59, and the Senate passed it on a narrow margin after a second vote. Supporters framed the plan as economic development and a way to channel dollars to addiction services, veterans’ homes, and housing programs. Opponents, including retail casino operators, cautioned that excluding commercial properties from the online market could cannibalize floor revenue and put jobs at risk.

Regulators, rivals, and enforcement concerns

State regulators highlighted a parallel problem: gray-market and offshore casino-style sites already serving Mainers. The Gambling Control Unit flagged sweepstakes-style operators and other dual-currency platforms as unregulated risks that can mask real-money play. Supporters of the tribal model argued a legal, licensed marketplace would draw players back to vetted platforms and improve consumer protections. Detractors countered that expansion could increase participation and addiction risk without a clear, sustained treatment funding plan.

Political and legal pressure points

Governor Janet Mills held the bill for review rather than signing it immediately, creating uncertainty for tribes, vendors, and regulators. That pause complicates licensing timelines and vendor contracts, and it left room for the legal challenge now underway. The state’s only other commercial casino, Hollywood Casino, also opposed the bill for similar workforce and revenue concerns. Public health agencies and the Gambling Control Board raised objections too, underscoring that the dispute crosses economic, constitutional, and public-health lines.

The wider policy context: sports betting, sweepstakes, and state revenue

Maine opened mobile sports wagering under tribal exclusivity in 2023, producing taxable revenue that supporters say proves a regulated approach can benefit the state. Lawmakers and regulators also moved to clamp down on sweepstakes and unlicensed operators, proposing fines and enforcement tools to protect licensed markets. Those enforcement efforts were pitched as complementary to a legal online casino rollout—yet they also intensified the stakes for whichever direction policymakers choose.

What’s at stake for communities and industry players

LD 1164 earmarks gross receipts for addiction services, opioid treatment, veterans’ care, and housing—programs that depend on steady, predictable revenue streams if the market opens. Commercial casinos argue that a tribal-only model reshapes an existing, regulated industry without broad stakeholder buy-in or voter approval, risking long-term economic impacts for in-person operations. Meanwhile, offshore and sweepstakes operators remain a live threat to consumer protection goals if a regulated alternative is delayed.

Legal timetable and next moves

There’s no set date for when iGaming would go live; the law would take effect 90 days after the legislature adjourns if enacted. Oxford Casino’s lawsuit raises constitutional questions likely to slow implementation and could trigger expedited court review depending on the claims. At the same time, state lawmakers continue to debate problem-gambling measures, including a separate bill to ban credit-card use for sports betting—an attempt to limit harms while the larger market design is hammered out.

The dispute puts Maine at a crossroads: lawmakers, regulators, tribes, and commercial operators must balance tribal sovereignty, legal competition, public-health priorities, and consumer protection. As the legal process plays out, regulators and market participants will be watching how courts interpret exclusivity and whether the state can reconcile economic goals with constitutional constraints. Terms and conditions apply to any future licensed offerings, and decisions here will shape who can legally offer online casino games in Maine for years to come.
