The Supreme Court has refused to grant certiorari to a coalition of environmental groups challenging President Trump’s border wall.

According to Fox News:

The groups, led by the Center for Biological Diversity, challenged a 1996 law giving the president authority to fight illegal immigration and border crossings, and limiting some legal challenges.

The coalition claimed that the Trump administration did not conduct sufficient environmental impact studies for the construction and that endangered species like the jaguar and Mexican wolf would be adversely affected by the barrier.

They had asserted in their case that the law’s allowance for the secretary of Homeland Security to waive any laws necessary to allow the quick construction of border fencing violates the Constitution’s separation of powers. The D.C. Circuit Court of Appeals had dismissed the case, citing a prior case from 2007 with “a nearly identical context.”

“This Court finds that precedent persuasive, and it compels the conclusion that Plaintiffs’ complaint fails to state plausible constitutional claims as a matter of law,” the Circuit Court’s ruling said.

This is a big win for Trump’s border wall which has faced environmental challenges since the beginning.
