Supreme Court Asked to Keep Lower Court Halt on Texas Border Wall Construction

Three plaintiffs – an environmental organization, a local landowner and a group formed to preserve a church – have asked the U.S. Supreme Court to leave in place a district court order that temporarily stops construction of a border wall in the Big Bend region of southwestern Texas. The request was filed on Thursday, October 29, 2026, after the government sought a pause in the order.

What the lower court ordered

U.S. District Judge Kathleen Cardone issued a temporary injunction on Oct. 2, barring the Department of Homeland Security (DHS) from continuing wall work until the agency complies with environmental and other applicable laws. In her Oct. 14 opinion, Cardone said the plaintiffs are likely to succeed on a claim that the waivers issued by then‑Homeland Security Secretary Kristi Noem and her successor Markwayne Mullin exceed the authority granted by the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA).

Major‑questions doctrine at the center

Cardone applied the major‑questions doctrine, which requires Congress to speak clearly when delegating decisions of “vast economic or political significance.” She found that the waivers allowing the DHS to ignore all legal requirements for wall construction in Big Bend were not clearly authorized, especially because the area accounts for only 0.3%‑2.2% of border apprehensions despite covering more than 25% of the U.S.–Mexico border.

Government’s push to lift the halt

The Trump administration asked the Supreme Court on Oct. 21 to pause Cardone’s injunction and reverse it. Solicitor General D. John Sauer argued that the district court lacked authority to consider the major‑questions claim and that Congress did clearly give the DHS power to waive requirements for expedited wall building.

What this means for ordinary people

If the Supreme Court lets the lower‑court order stand, construction in the remote, ecologically sensitive Big Bend area will remain paused. Residents, landowners and visitors to nearby parks will not see new blasting, bulldozing or road work for now. The plaintiffs also note that DHS voluntarily paused work earlier after local opposition, suggesting the pause causes no lasting harm to the agency.

People living near the border or planning trips to Big Bend National Park should monitor news for any change in the status of the wall project. No specific deadlines for further action were mentioned in the filings.

When a lawyer can help

Anyone who owns land in the affected area, or who is concerned about environmental impacts, may want to consult an attorney to understand how a potential resumption of construction could affect property rights, permits or local regulations.
