TITLE: Wabanaki Nations Intervene in Maine Online Casino Lawsuit Against Oxford Casino
BODY:
On April 3, 2026, the four Wabanaki tribes formally intervened in a lawsuit challenging Maine's online casino law. The Houlton Band of Maliseet Indians, the Mi'kmaq Nation, the Passamaquoddy Tribe, and the Penobscot Nation filed a joint motion to intervene, which a judge granted the following day.
The dispute centres on Maine legislation enacted in January 2026 that grants the Wabanaki Nations exclusive rights to operate online casino games. Oxford Casino, backed by Churchill Downs Inc., challenged the law as creating an illegal "race-based monopoly" in violation of equal-protection principles. The tribes argue that exclusive online casino access generates independent revenue to fund health care, food assistance, public infrastructure, and other services benefiting tribal and nontribal residents. Tribal attorneys contend that Oxford's equal-protection argument threatens the Nations' unique sovereign status and could undermine longstanding legal principles protecting tribal-state arrangements.
Governor Janet Mills allowed the bill to become law on January 8 without her signature, following tribal lobbying despite objections from some state agencies. The litigation injects significant uncertainty into Maine's move to become the eighth U.S. state with legalized online casinos. If the court sides with Oxford, exclusive tribal online casino rights could be curtailed or require legislative amendment, potentially opening market access to commercial operators. Conversely, an affirmation of tribal exclusivity would cement a model where tribes control online casino supply in Maine. Either outcome carries implications for player protections, market competition, revenue distribution, and how states balance tribal sovereignty with commercial access. The ruling could also impact state-tribe compacts in other jurisdictions.
