On Thursday, the Supreme Court imposed strict new limits on the Clean Water Act. The Court’s decision in Sackett v. EPA is likely to do serious harm to the government’s ability to quell water pollution, including in major waterways such as the Mississippi River and the Chesapeake Bay.

Meanwhile, Justice Clarence Thomas wrote a concurring opinion that would so severely limit Congress’s power to legislate that he might as well have taken several volumes of the United States Code and lit them on fire.

To be clear, a concurring opinion is not the law — it merely reflects the views of the justices who sign onto it. And this particular opinion is unlikely to garner five votes to become law unless the Court’s membership changes drastically.

Thomas’s approach endangers countless laws governing private business, from rules requiring health insurers to cover people with preexisting conditions to the ban on whites-only lunch counters. And even that is underselling just how much law would be snuffed out if Thomas’s approach took hold. [Continue reading…]
