Supreme Court overturns Chevron doctrine

Relentless v. Department of Commerce, a pair of consolidated cases asking the Court to reverse its seminal decision in Chevron v. NRDC. As expected following oral argument, the Court accepted the invitation and overruled Chevron in a 6–3 decision.

In a 6-3 ideologically divided ruling, the judges tossed out the Chevron doctrine, which says judges should yield to agencies' reasonable readings of ambiguous laws when crafting rules to do things like constrain artificial intelligence, improve the health care system and protect against climate change.

The decision effectively ends a legal precedent known as “Chevron deference,” after a 1984 Supreme Court ruling. That decision held that when Congress passes a law that lacks specificity, courts must give wide leeway to decisions made by the federal agencies charged with implementing that law.
