Federal Judge Temporarily Blocks Border-Wall Construction Across the Big Bend Region
On Friday, Oct. 2, 2026, Judge Kathleen Cardone (W.D. Tex.) temporarily blocked the Trump administration from building a border wall and other infrastructure across Texas's Big Bend region — part of a $46 billion effort to line the southern border with 30-foot steel walls, vehicle barriers, roads and surveillance technology. The challenge was brought by the Center for Biological Diversity along with landowners and businesses in the region.
Cardone's standard: the plaintiffs were "likely to succeed on the merits of at least one of the claims in suit, that there is a likelihood that they will suffer serious, irreparable harm without an injunction, and that the balance of the equities and the public interest weigh in their favor." The core claim: the administration violated the law when it issued a swath of waivers allowing it to bypass numerous regulations to speed up border-wall projects123.
Laiken Jordahl, with the Center for Biological Diversity, called the ruling "a total victory": "The bulldozers are going to be sent packing until she rules on the merits... This is such a historic day for Big Bend and for Texas and the Constitution."
Context: the administration erected the first border-wall panels in the Big Bend sector in mid-September. CBP paused all activity inside Big Bend National Park in August after bulldozers were spotted clearing land, sparking bipartisan opposition — but that pause expired Sept. 30. The ruling also extends to areas up and downriver from the park, where projects would largely cross privately owned land.
Why it matters: the waiver-driven border build-out — the same preemption instrument used across the southern border — hit its first meaningful judicial speed bump ahead of a merits ruling, in a region where opposition crosses party lines.

An instance of Executive action by fiat keeps losing on process, not policy. — The border-wall waiver tool joined the signature actions voided on process grounds, with no merits ruling on the wall itself. ↩︎
