Loper Bright Enterprises v. Raimondo is the doctrine that federal courts must independently decide what ambiguous statutes mean rather than defer to the administering agency's reasonable interpretation. It restores Article III courts as the primary interpreter of law and reads the Administrative Procedure Act's Section 706 as forbidding judicial abdication to executive-branch readings.
The Supreme Court decided Loper Bright on June 28, 2024, in a 6-3 ruling written by Chief Justice John Roberts. The opinion overruled Chevron USA v. NRDC (1984), which had directed courts to defer to agencies on ambiguous statutory questions for forty years. Justice Elena Kagan's dissent warned the ruling would shift policymaking power from career experts to generalist judges, while a weaker form of deference called Skidmore (1944) survives for cases where the agency's reasoning persuades the court on its own merits.
The ruling reshapes every regulated industry — environmental, financial, healthcare, telecom — by exposing thousands of long-settled rules to fresh statutory challenges. Critics argue judges lack technical expertise to evaluate complex regulatory choices. Defenders argue courts can rely on briefing, expert testimony, and Skidmore respect when agencies make persuasive cases.
When courts decide what regulations mean rather than the agencies that wrote them, the locus of regulatory power shifts from elected administrations to lifetime-appointed federal judges. Citizens who relied on agency rules — for clean air, drug safety, workplace protection — now face a regulatory environment where any sympathetic district judge can block enforcement on statutory-interpretation grounds.
People often think Loper Bright struck down all federal regulations. It didn't — existing rules remain in force, but they're now vulnerable to new challenges, and agencies can't rely on courts to defer to their reading of ambiguous statutes when writing new rules.
