A coalition of landowners, ranchers, business owners, and a nonprofit organization filed a federal lawsuit in the U.S. District Court for the District of Columbia to stop the Trump administration from constructing a border wall and associated infrastructure across the remote Big Bend region of Texas, according to reports. The legal challenge targets a broader federal effort to line the approximately 2,000-mile southern border with 30-foot steel bollard walls, vehicle barriers, and surveillance technology as part of a $46 billion initiative.
Landowners Launch Federal Challenge Over Big Bend Border Wall
The lawsuit was brought by Conserve Big Bend and six individual landowners, drawing backing from dozens of residents along the border. Plaintiffs argue that the Department of Homeland Security unlawfully misused statutory waiver authority to fast-track the project.
Disputing the Legal Basis of ‘High Illegal Entry’
Under Section 102 of the 1996 Illegal Immigration Reform and Immigrant Responsibility Act, the secretary of homeland security holds expedited powers to waive dozens of federal environmental, archaeological, and protective statutes. However, that authority strictly requires the targeted zone to be formally designated as an area of high illegal entry.
In the federal complaint, plaintiffs contend that this designation is legally and factually unsupported in the Big Bend region. The Big Bend Sector spans 517 miles—accounting for more than a quarter of the entire U.S.-Mexico border—yet the sector has recorded the fewest apprehensions of any southwest border sector annually for the past 53 years. Customs and Border Protection data cited in the lawsuit indicates that the sector accounted for just 1.16% of total southwest border apprehensions between fiscal years 2021 and 2025. Furthermore, apprehensions dropped 74% from fiscal year 2023 to fiscal year 2025, reaching the sector’s lowest annual total since 1963.

Clara Bensen, board member with Conserve Big Bend and director of communications for the No Big Bend Wall initiative, stated that you cannot legally bypass the laws of this country by fabricating an emergency that does not exist, adding that declaring over 500 miles of steep cliff faces and perilously rugged desert an area of high illegal entry is not just detached from reality, but under federal law, it is arbitrary, capricious, and unlawful.
Environmental, Cultural, and Practical Concerns
Opponents of the wall project emphasize the unique geography and cultural heritage of the area, which stretches from Fort Quitman to Amistad Dam. David Keller, a regional archaeologist, historian, landowner, and board member with Conserve Big Bend, stated that government officials were woefully unprepared for the hornet’s nest they stirred up because they had no idea how much they love this place.

Native American groups have cautioned that construction threatens religious sites and restricts their capacity to practice their faith. Environmental organizations warn that barriers could provoke flooding and disrupt wildlife migration patterns. Additionally, ranchers and landowners whose properties border the Rio Grande have questioned how they will manage livestock and irrigate crops if denied access to the river.
National Park Outcry and Field Work Status
Public backlash intensified around proposed construction inside Big Bend National Park, located in the southwestern corner of Texas along the Rio Grande. Publicly released plans for the park have featured a new road, detection technology, and barriers to stop cross-border vehicle traffic. Public outrage followed the sighting of bulldozers clearing land within the park in August.
In response to the outcry, CBP Commissioner Rodney Scott temporarily paused construction-related activities inside the park. Despite the pause, field work has already commenced on Big Bend 1 and 3. Numerous affected property owners have received Notice of Interest letters alongside proposed Right-of-Entry agreements granting government access for up to three years for surveys, appraisals, and construction.
