Scholars’ Circle – Wetlands Protection, the Clean Water Act and the US Supreme Court – July 2, 2023

We examine Sackett vs. EPA, in a broader context what this means for the implementation of the Clean Water Act, what it means specifically for wetlands. What is the implication of framing the EPA as being against economic development?

What exactly does “waters of the United States” mean as discussed in this decision? [ dur: 58mins.]
