How could the injunction blocking border barriers affect Markwayne Mullin's policy agenda?
Injunction halts border barrier plans championed by Markwayne Mullin The preliminary injunction issued by Judge Kathleen Cardone has halted the construction of border barriers in the Big Bend Sector of Texas. This action directly blocks the policy initiative that Secretary Markwayne Mullin had promoted, which involved waiving environmental laws under a 1996 law. The DHS had begun preliminary steps to build physical barriers along a 517-mile stretch in remote west Texas, but the court's ruling stopped the associated construction and waivers.

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.

Why it matters
For Markwayne Mullin, as the Secretary of Homeland Security, this injunction represents a significant operational setback. He was the proponent of the policy that sought to accelerate border security measures by waiving environmental reviews, but the court's decision has immediately halted the associated construction plans in the Big Bend Sector.
This dispute centers on the interpretation of a 1996 law regarding border barriers. While the government argued that the Big Bend Sector met the criteria for 'high illegal entry' based on apprehensions and drug seizures, Judge Cardone concluded that the region could not be considered to have high levels of illegal entry, thereby invalidating the basis for the waiver.
What we don't know yet
- Will the government appeal Judge Cardone's injunction to the U.S. Court of Appeals for the 5th Circuit?
- How will DHS adjust its border barrier strategy given the current legal block in the Big Bend Sector?
