Missing Case, Mixed Facts: Supreme Court Environmental Analysis Review

The Bigger Picture the Article Misses: A Three-Case Demolition of EPA Authority

The article frames the Supreme Court's environmental rulings as a backdrop to Trump's agenda, but the more important story is the reverse: the Court's decisions didn't just clear the way for Trump — they permanently restructured the legal architecture of environmental regulation regardless of who holds the presidency. The article also omits a critical 2022 case, West Virginia v. EPA, which established the "major questions doctrine" and was arguably the most consequential environmental ruling of the decade. Understanding all three cases together reveals a coordinated doctrinal shift, not a series of isolated rulings.

What the Article Gets Right — and What It Understates

The article correctly identifies Sackett v. EPA (2023) and Loper Bright Enterprises v. Raimondo (2024) as landmark cases. However, it significantly understates the scale of damage from each.

On Sackett, the article says the Clean Water Act was "gutted" — but the concrete numbers are striking. The ruling redefined "Waters of the United States" (WOTUS) so narrowly that approximately half of all U.S. wetlands lost federal Clean Water Act protection entirely. This isn't a bureaucratic technicality. Fifty-five percent of water flowing out of U.S. river basins can be traced back to intermittent streams that are now unprotected under federal law. In New Jersey alone, over 4.2 million people receive drinking water from public systems that rely at least in part on streams no longer covered by federal protections. These are public health consequences, not just environmental ones.

The article also describes the Chevron deference issue somewhat inaccurately. It characterizes Chevron as "the idea that when a law is vague, courts should defer to federal agencies due to their limited knowledge" — but the logic was actually the opposite. Chevron deference existed precisely because agencies were presumed to have superior technical expertise, not limited knowledge. The Supreme Court's Loper Bright ruling explicitly rejected this, stating that "agencies have no special competence in resolving statutory ambiguities." This is a philosophical reversal: courts now substitute their own judgment for that of scientists and technical regulators.

The Case the Article Omits Entirely: *West Virginia v. EPA* (2022)

The article traces the pattern back to Sackett in 2023, but the doctrinal groundwork was laid a year earlier in West Virginia v. EPA (2022), which the article does not mention at all. In that ruling, the Court struck down Obama's Clean Power Plan and introduced the "major questions doctrine" — the principle that when a regulatory action is economically or politically significant, agencies cannot act without explicit Congressional authorization. This doctrine is now a powerful tool to challenge virtually any major EPA rulemaking on climate or pollution, because Congress rarely writes laws with the specificity required to survive this new standard.

Together, these three cases form a sequence: West Virginia (2022) limits what the EPA can regulate without Congress; Sackett (2023) shrinks the physical territory the EPA can protect; Loper Bright (2024) removes the legal deference that allowed the EPA to interpret ambiguous statutes in favor of protection. The article presents two pieces of a three-part puzzle.

The Structural Shift: From Agency Expertise to Judicial Supremacy

The overturning of Chevron deference is perhaps the most far-reaching change because it applies across all regulatory domains, not just environment. The Chevron doctrine, established in 1984, had been cited in more than 18,000 judicial opinions over nearly 40 years. Its elimination means that every ambiguous environmental statute — and there are many — is now subject to fresh judicial interpretation, with no presumption in favor of the agency's reading.

The practical consequence is a fragmented regulatory landscape. Different federal circuit courts may now interpret the same environmental statute differently, creating a patchwork of standards. The pro-environment Ninth Circuit and more conservative circuits could reach opposite conclusions on identical regulatory questions. A former EPA general counsel under Trump himself described the cumulative effect as "an administrative law revolution."

Critically, this also opens the floodgates for litigation. Every EPA rule is now more vulnerable to legal challenge, because challengers no longer need to overcome the presumption that the agency's interpretation is reasonable. Environmental groups lose a structural legal advantage they relied on for decades; industry groups gain a structural advantage they never previously had.

What the Article Gets Right About State-Level Action

The article's pivot to state legislation as a path forward is well-grounded. States like Massachusetts with their own Environmental Policy Acts are genuinely important, and the Montana ruling the article references — where a state judge found that agencies violated the constitutional right to a clean environment — reflects a real and growing trend of state-level environmental rights litigation. This is not wishful thinking; it is a documented legal strategy gaining traction as federal protections erode.

However, the article's optimism about midterm elections shifting Congressional power deserves scrutiny. Even a Democratic Congress would face the same Supreme Court, the same major questions doctrine, and the same post-Chevron legal framework. Passing new, more specific environmental legislation could help, but the Court's current composition — with three Trump-appointed justices enabling consistent 6-3 majorities on regulatory cases — means the judicial landscape is unlikely to shift quickly. The Supreme Court has also already granted certiorari on multiple additional environmental cases, positioning itself to further shape environmental law in coming terms.

Historical Reversal Worth Noting

The article does not provide historical context for how dramatic this reversal is. In United States v. Riverside Bayview Homes (1985), the Supreme Court unanimously upheld federal jurisdiction over wetlands adjacent to navigable waters, citing their ecological importance. The Sackett ruling effectively dismantled what a unanimous Court had affirmed 40 years earlier. This is not incremental legal evolution — it is a deliberate doctrinal reversal by a Court that has fundamentally reconceived the relationship between Congress, agencies, and the judiciary.
