Federal judge halts Big Bend border construction and stays DHS waivers

A preliminary injunction bars border barriers and related ground disturbance across the Big Bend Sector unless the government follows applicable law, while staying three DHS environmental and cultural-law waivers.

Event: October 2, 2026

The order reaches the entire Big Bend Sector

U.S. District Judge Kathleen Cardone issued a preliminary injunction on October 2 barring the federal government from constructing border barriers or related infrastructure, or undertaking associated ground disturbance, anywhere in the Big Bend Sector unless it complies with all applicable laws. The two-page order also stays the effect of three Department of Homeland Security waivers covering Big Bend National Park, the Lower Canyons and other parts of the sector for the injunction's duration. [1][4][3]

The order followed an evidentiary hearing and says the plaintiffs showed a likelihood of success on at least one claim, a substantial threat of irreparable injury, and equities and public interest favoring interim relief. It does not identify the successful claim or finally decide the lawsuit; Cardone said a detailed memorandum would follow. Construction complying with applicable law is not prohibited by the text, but the three broad waivers cannot be used while the injunction remains in effect. [1][6][5]

The waived laws covered environmental, cultural and burial protections

DHS invoked Section 102 of the Illegal Immigration Reform and Immigrant Responsibility Act to waive statutes for border construction, saying the projects were needed for operational control. The official notice lists the National Environmental Policy Act, Endangered Species Act, Clean Water Act, National Historic Preservation Act, Migratory Bird Treaty Act and Native American Graves Protection and Repatriation Act among the federal requirements set aside, along with related regulations and state laws. [2][1]

Plaintiffs include landowners, a preservation group tied to historic Ruidosa Church and a river guide. Local reporting describes concerns about private property, springs, wildlife habitat, archaeological sites and culturally significant land. Reuters and AP reported that planned infrastructure included not only wall segments but also roads, vehicle barriers and surveillance technology. The precise mix varies by location, so the ruling should not be read as saying a 30-foot wall was planned for every mile of the sector. [5][6][3][4]

The government can appeal, and a separate lawsuit had a different result

Customs and Border Protection told AP and local public radio that the government was reviewing the order with the Justice Department and remained confident in its legal authority. The agency has defended construction as a border-security measure. The injunction does not erase that policy position; it requires the government to proceed under laws that the stayed waivers had displaced unless a higher court or later district-court ruling changes the result. [4][6][2]

The Big Bend Sentinel reported that another federal judge denied a temporary restraining order in a separate challenge brought by environmental organizations, an important procedural difference rather than a contradiction about the same plaintiffs. Spanish-language reporting by El Pais described the injunction and regional scale; names, dates, distance conversions and the preliminary posture were checked against the English order and U.S. reporting. The next decisive documents will be Cardone's full reasoning and any government appeal. [5][7][1]
