Supreme Court Lifts Big Bend Wall Injunction, Citing No 'Major Questions' Claim

The Supreme Court on Monday cleared the Trump administration to resume border barrier and road construction in West Texas's Big Bend region while litigation continues. The unsigned order paused an injunction issued by U.S. District Judge Kathleen Cardone. Only Justice Ketanji Brown Jackson would have denied the government's request, without explanation.

The court found the government is "exceedingly likely to prevail" on its argument that Cardone lacked jurisdiction over the challengers' claim, which rested on the major questions doctrine. "There is no such thing as a 'constitutional' major-questions claim," the justices wrote, as reported by SCOTUSblog. For practitioners, that single sentence may matter more than the procedural outcome itself.

What does the ruling change?

The order is a stay, not a final merits decision. The justices declined the administration's separate request to reverse Cardone's ruling outright. But the stay restores the government's ability to build while the case proceeds, and the reasoning signals how the court views the underlying jurisdictional fight. Judge Cardone's order, the court said, "impedes the Government from advancing its 'compelling interests' in border security and integrity." The justices added that Congress's immigration law "reflects a clear preference for expeditious border construction over the very harms respondents assert."

The court also weighed money. It cited costs of nearly half a million dollars per day that the government said it incurred while work sat on hold. Takeaway: injunctions halting border construction now face a steep path at the Supreme Court.

Why the major questions holding matters

The challengers had argued the case through the major questions doctrine, a theory the court has used to curb agency power in recent terms. Monday's order forecloses that route here, at least at the constitutional level. The court said no such claim exists. Litigators challenging federal border waivers will need a different doctrinal vehicle.

The underlying dispute involves three waivers of environmental and conservation laws. Then-Homeland Security Secretary Kristi Noem issued the first in February; her successor, Markwayne Mullin, issued two more in May and July. The government says the project covers 341 miles of construction. Takeaway: statutory waiver authority, once invoked, now looks difficult to stall with emergency litigation.

What are the competing claims about the border?

The administration says about 89,000 people have been detained trying to cross the sector in recent years, according to NBC News. Challengers counter that the area has the lowest migrant apprehension rates anywhere along the southern border.

Solicitor General D. John Sauer warned that halting the project risked "creation of a massive vulnerability in border protection that risks funneling illegal entry and trafficking into the unsecured Big Bend Sector," according to CBS News. Takeaway: the record before the court was a factual dispute the justices resolved, for now, in the government's favor.

Who is challenging the project, and what happens next?

The Center for Biological Diversity, Friends of the Ruidosa Church and Danny Miller, a river guide who owns property in the area, brought the lawsuit. "The Trump administration and its contractors are hellbent on destroying one of America's greatest national parks," the center's Laiken Jordahl said in a statement.

The group emphasized that Monday's order is not a final ruling on whether the waivers are legal. It said the decision allows construction to resume in Big Bend National Park and along more than 500 miles of the Rio Grande.

The project drew pushback this summer from Republican and Democratic lawmakers, ranchers and local law enforcement in Texas after bulldozers arrived at the park. Customs and Border Protection then paused work inside the park through the end of September. CBP Commissioner Rodney Scott has said the 30-foot wall itself will not cut through the national park, but more than 200 miles of patrol roads and about 17 miles of vehicle barriers would. Takeaway: the litigation continues, but construction now moves faster than the docket.
