Ysleta del Sur Pueblo v. Texas: The 2022 Ruling, Explained

On June 15, 2022, the U.S. Supreme Court decided Ysleta del Sur Pueblo v. Texas, a case that began as an argument about electronic bingo machines outside El Paso and ended as a durable statement about how much authority a state holds over gaming on tribal land. The decision is short, the vote was close, and its practical consequences are still working through Texas today.

The problem the case had to solve

Two Texas tribes — the Ysleta del Sur Pueblo and the Alabama-Coushatta Tribe of Texas — regained federal recognition through the Ysleta del Sur Pueblo and Alabama and Coushatta Indian Tribes of Texas Restoration Act of 1987. That statute predates the Indian Gaming Regulatory Act by a year, and it contains its own gaming provision. The provision states that gaming activities prohibited by the laws of Texas are also prohibited on the tribes' lands.

The interpretive question was what "prohibited" means. Texas argued that the Restoration Act imported the state's entire body of gaming law — including its regulations — onto tribal land, so that any activity Texas regulated in a particular way had to be conducted the same way on the reservation. The tribes argued the Act imported only Texas's outright bans, leaving everything Texas permits in some form open to tribal regulation.

The stakes were concrete. Texas allows bingo, but restricts it largely to charitable purposes with limits on prizes and operations. The Ysleta del Sur Pueblo operated electronic bingo at its Speaking Rock facility on terms that did not match the state's charitable framework. On Texas's reading, that was unlawful. On the tribe's reading, because Texas permits bingo rather than banning it, the state's specific restrictions did not travel onto tribal land.

What the Court held

Writing for a five-justice majority, Justice Neil Gorsuch held that the Restoration Act bans on tribal land only those gaming activities that Texas bans outright. Justices Breyer, Sotomayor, Kagan and Barrett joined. The Court vacated the Fifth Circuit's contrary ruling and remanded for further proceedings.

The ruling displaced a reading of the Restoration Act that had governed in the Fifth Circuit since the 1990s, under which the state's gaming laws applied on tribal land as "surrogate federal law" in considerably broader terms. Under that earlier framework, tribal gaming facilities in Texas spent years in enforcement litigation, opening and closing as court orders moved.

The reasoning turned on the distinction between prohibition and regulation — the same line the Supreme Court had drawn thirty-five years earlier in California v. Cabazon Band of Mission Indians. If a state forbids an activity entirely, it is prohibitory. If a state permits the activity but sets rules for how it is conducted, it is regulatory. The Restoration Act's text reached only the first category.

The practical translation: if Texas allows a form of gaming to exist anywhere in the state under any conditions, the two Restoration Act tribes may offer it and regulate it themselves. If Texas bans it outright, they may not.

Why it matters beyond Texas

The decision matters for three reasons. First, it preserved bingo-based gaming for two tribes whose facilities had faced repeated closure litigation across three decades. Second, it reaffirmed the prohibitory-regulatory distinction at a moment when several states were arguing for broader authority over tribal lands — reasoning that resonates well beyond the Restoration Act's narrow scope. Our explainer on California v. Cabazon Band covers the origin of that framework.

Third, it left a distinctive legal position in place. The Restoration Act tribes in Texas operate under a statute separate from IGRA's Class II and Class III architecture, which means their gaming authority is defined by Texas's own permissive and prohibitory choices rather than by a tribal-state compact. Texas has no tribal-state compacts. Understanding what each category of gaming permits under the ordinary federal framework is covered in our Class II versus Class III explainer.

What it did not decide

The ruling did not authorize Class III casino gaming in Texas, and it did not give the tribes unlimited discretion. Activities Texas bans outright remain banned on tribal land. Nor did it resolve the position of the Kickapoo Traditional Tribe of Texas, which was federally recognized through separate legislation and operates under a different statutory arrangement.

Since the decision, gaming activity at the two Restoration Act tribes' properties has expanded considerably, and legislative proposals to place Texas tribes under the standard IGRA framework have continued to be introduced in Congress.
