Supreme Court Clears Big Bend Border Wall as Justices Lift Injunction

The Supreme Court on Monday cleared the way for the Trump administration to resume building border barriers across the Big Bend region of West Texas, lifting a federal judge’s order that had halted construction for more than a month.

The justices voted 8-1 in an unsigned, five-page order to pause the injunction while the underlying lawsuit continues. Justice Ketanji Brown Jackson was the only member of the court to publicly dissent, and she did not write an opinion explaining her position.

The decision is a practical win for the administration, but it is not a final ruling on whether the border wall project itself is lawful. The case now returns to the lower courts, where the challenge to the government’s use of sweeping environmental waivers will be fought on a full record.

A month-long halt, lifted

The injunction at issue was issued on 2 October by U.S. District Judge Kathleen Cardone in El Paso. It froze barrier and road construction across the entire Big Bend Sector, a stretch of more than 500 miles along the Rio Grande that covers more than a quarter of the U.S.-Mexico border.

The lawsuit was brought by the Center for Biological Diversity, a Big Bend-area river guide and landowner, and Friends of the Ruidosa Church, a group working to preserve a historic adobe church in Ruidosa, Texas, which the plaintiffs say is threatened by the construction.

The plaintiffs challenged a series of waivers issued by the Department of Homeland Security to speed up construction of barriers and roads, bypassing a range of environmental and conservation laws. The waivers were issued under a 1996 federal law aimed at facilitating barrier construction in areas of high illegal crossings. Former Homeland Security Secretary Kristi Noem issued waivers in February, and her successor, Markwayne Mullin, issued further waivers in May and July, after finding the region to be an area of high illegal entry.

The administration asked the Supreme Court to intervene on 21 October after Judge Cardone declined to pause her own ruling. The emergency application, numbered 26A560, was granted on Monday.

What the court said

The court’s brief order said the law at issue likely bars judges from reviewing the waiver claims at all. NPR reported that the five-page decision concluded the federal judge who issued the injunction did not have the authority to weigh in. It concluded that the lower court’s order “impedes the Government from advancing its ‘compelling interests’ in border security and integrity,” and that the government’s interest “outweighs any aesthetic, recreational and environmental harm alleged by respondents.”

The ruling does not decide whether the waivers were lawful. An emergency stay pauses a lower-court order while a case proceeds; it is not a judgment on the merits. The challengers can still press their claims in district court, and the case could reach the Fifth Circuit on appeal.

The decision drew an immediate response from the plaintiffs. The Center for Biological Diversity said the ruling suspends the injunction while the lawsuit proceeds and stressed that it is not a final ruling on the legality of the waivers. The group said construction could now resume in Big Bend National Park and along more than 500 miles of the Rio Grande, and could also begin in Big Bend Ranch State Park.

What gets built, and where

The administration has said most of the construction in the Big Bend Sector will take place on privately owned land, with barriers and upgrades planned along the full 517-mile stretch. Big Bend National Park itself would receive a 17-mile noncontiguous vehicle barrier system, but not the 30-foot pedestrian barrier planned for other areas, according to the administration.

The inclusion of the national park in the construction plans has drawn bipartisan criticism. Big Bend is one of the most remote and least visited national parks in the country, known for its sweeping desert canyons and unspoiled stretches of the Rio Grande. Opponents of the wall have argued that barriers and access roads would damage fragile desert habitat and historic sites; supporters say the sector has long been a gap in border enforcement.

It was not immediately clear on Monday whether work would resume inside the national park right away. Customs and Border Protection had paused park construction earlier this year, and no statement from the agency, the Department of Homeland Security or the plaintiffs was immediately available after the ruling.

A court that keeps siding with the administration on the border

The order is the latest in a series of emergency-docket decisions in which the Supreme Court has allowed the administration’s immigration and border policies to proceed while legal challenges play out. The courts have not always ruled the administration’s way: just last week, a federal judge blocked a deportation flight that would have sent Afghans to Taliban-controlled territory. It comes as the administration’s wider immigration crackdown remains the subject of intense political debate, weeks after the midterm elections reshaped control of Congress.

The case also adds to a busy term for the court. The justices heard arguments in a separate case on the Supreme Court’s docket this term concerning lawsuits against federal officers, and the court has already weighed in this term on emergency funding and tariff disputes.

For the Big Bend, the immediate effect is straightforward: the bulldozers can return. The legal question of whether the waivers that made the project possible can survive judicial review will be decided later, in a courtroom far from the desert.
