BORDER WALL LAWSUIT: While the center previously filed a lawsuit over open records, this one focuses on constitutional issues. We'll be covering this more in the coming days.
TERLINGUA, Texas— The Center for Biological Diversity, Friends of the Ruidosa Church, and a Big Bend-area river guide and landowner sued the Department of Homeland Security today for unconstitutionally waiving dozens of laws to fast-track border wall construction through the Big Bend region of Texas. The lawsuit argues the department is exercising powers Congress never authorized.
“The Department of Homeland Security has unconstitutionally gutted our nation’s bedrock environmental laws to build a wildlife-killing wall that would permanently lock away the Rio Grande,” said Laiken Jordahl, national public lands advocate at the Center for Biological Diversity. “This is straight out of the playbook they used in Arizona, where federal contractors blew up sacred Indigenous sites, bulldozed canyon walls and drained precious aquifers to build border walls. They’re trying to slam an iron curtain through the Big Bend region, gouging a wound that will never heal into one of America’s most beautiful wild places.”
Today’s lawsuit, filed in U.S. District Court in the Western District of Texas, argues the federal government violated several constitutional provisions, including the major questions doctrine, which requires clear congressional approval for actions with vast economic and political consequences.
Today’s lawsuit also challenges Homeland Security’s claim that the Big Bend Sector is an “area of high illegal entry,” noting that it has the lowest number of crossings along the southern border and historically low apprehensions. The sector covers roughly a quarter of the border but accounts for just 1.3% of all Southwest border apprehensions.
