How could the injunction blocking DHS barrier plans affect U.S. Customs and Border Protection?
CBP's barrier construction plans in Big Bend Sector are halted by injunction A preliminary injunction issued by U.S. District Judge Kathleen Cardone has blocked the Department of Homeland Security's plans to construct a border barrier system along a 517-mile stretch in remote west Texas. Since U.S. Customs and Border Protection is responsible for enforcing immigration laws and managing border security, this injunction immediately halts the physical implementation of barriers in the Big Bend Sector. This area, which covers approximately one-quarter of the entire border, was slated for barrier construction despite having the lowest aggregate number of apprehensions per mile of border.

How it reaches U.S. Customs and Border Protection
-
The Department of Homeland Security sought fast-track permission from the Supreme Court to construct a border barrier system along a 517-mile stretch in remote west Texas. A federal district court issued a preliminary injunction in October, which was later upheld by Judge Kathleen Cardone on November 3, 2026, blocking the plans. The planned construction was intended for areas including Big Bend National Park and Big Bend Ranch State Park.
The full event1independent outlet -

Everything about United States Department of Homeland Security -
As U.S. Customs and Border Protection is the agency responsible for enforcing immigration laws and managing border security, the halt in DHS's barrier construction plans directly prevents CBP from implementing physical barriers in the Big Bend Sector. This sector, which has been unfortified since March 18, 1848, was the focus of the construction effort.

Why it matters
The construction of physical barriers is a core component of the U.S. government's strategy for border enforcement and immigration control. For U.S. Customs and Border Protection, the ability to deploy these barriers is a key operational mandate, designed to deter illegal entry and aid in drug interdiction. The injunction represents a significant legal and operational setback to this specific enforcement strategy in the Big Bend Sector.
This dispute centers on the interpretation of a 1996 law that allows DHS to waive environmental laws, provided the construction is in areas of 'high illegal entry.' The legal challenge, which Judge Cardone ruled could be considered, questions whether the Big Bend Sector meets this threshold, as the court found that if it did, every other sector would also qualify.
What we don't know yet
- Will the Supreme Court grant the Justice Department's request to pause the preliminary injunction?
- What criteria will the courts use to determine if the Big Bend Sector constitutes an area of 'high illegal entry'?
