The Supreme Court has given the Trump administration the green light to resume construction of a border wall in the Big Bend region of southwestern Texas, a decision encapsulated in an unsigned opinion issued on a Monday in November 2026. This ruling pauses a decision by a federal district judge who had earlier blocked the project. The recently delivered opinion notes that the government is likely to win its argument that the district court did not have jurisdiction to block the construction based on the major questions doctrine.
This dispute traces back to earlier this year when Department of Homeland Security (DHS) officials Kristi Noem and Markwayne Mullin authorized the waivers of various environmental laws, utilizing a provision from the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA). This provision endows the DHS secretary with the capacity to waive any legal requirements for the swift erection of border walls. Noem and Mullin justified these waivers by citing the Big Bend area as a significant entry point for illegal crossings.
Opponents of the construction, encompassing an environmental group, a local landowner, and a church preservation entity, legally contested the waivers. U.S. District Judge Kathleen Cardone initially ruled in favor of these challengers, halting construction until compliance with environmental laws could be assured. Cardone’s decision was grounded in the major questions doctrine which posits that decisions of substantial economic or political impact require clear congressional approval. She emphasized that while the Big Bend area constitutes a large segment of the U.S.-Mexico border, it accounts for a minor fraction of illegal apprehensions, raising doubts about the necessity of wall construction in this region.
Challengers sought to maintain the halting order, citing the adverse effects of the construction on the environment and local culture. However, the Supreme Court, while not reversing Judge Cardone’s ruling entirely, permitted the wall construction to continue pending further legal proceedings. The court indicated that the government’s need to secure the border outweighed the claims of ecological and cultural harm put forth by the challengers.
