[email protected]. ARTICLES LONGSTANDING AGENCY INTERPRETATIONS Anita S. Krishnakumar* How much deference—or what kind—should courts give to longstanding agency interpretations of statutes? Surprisingly, courts and scholars lack a coherent answer to this question. Legal scholars long have assumed that longstanding agency statutory interpretations are treated with heightened deference on judicial review, and federal courts sometimes have made statements suggesting that this is the case. But in practice, federal court review of longstanding agency interpretations—at both the U.S. Supreme Court and courts of appeals—turns out to be surprisingly erratic. Reviewing courts sometimes note the longevity of an agency’s statutory interpretation as a plus factor in their deference analysis but at other times completely ignore or dismiss an agency interpretation’s longevity. Moreover, judicial rhetoric about the relevance of longevity in the review of agency statutory interpretations is inconsistent from case to case.
