The Chevron doctrine – the bedrock principle of administrative law under which courts afforded deference to administrative agency interpretations in the face of statutory ambiguity – is no more.  On June 28, 2024, the U.S. Supreme Court issued a long-anticipated decision that addresses the authority of regulatory agencies to dictate policy and the extent to which courts will exercise their own judgment as to the meaning of a statute and how that may bound agency decisions. 

When can Supreme Court precedent be overruled? Two recent decisions carry on a recent and lively debate among the Justices over the concept of “stare decisis,” and provide significant guidance on how Justices Thomas and Kavanaugh approach the question.

Yesterday the Supreme Court of the United States issued its most significant Clean Water Act decision in more than a decade, resolving a split among lower courts over the reach of the Clean Water Act’s “point source” or National Pollutant Discharge Elimination System (NPDES) program. Pollutants travel to bodies of water in many ways: by pipe, ditch, or runoff, for example. The Clean Water Act defines some of those ways of moving pollutants as “point sources”—specifically, pipes, ditches, and similar “discernible, confined and discrete conveyance[s]”—and bans the “addition of any pollutant to navigable waters from any point source” without an NPDES permit. But no similar permitting requirement applies to pollution added from nonpoint sources, which is instead controlled by state and other federal environmental laws.
