Q1: What area of law does Kisor v. Wilkie primarily address?
Administrative Law
Q2: What was the central legal issue in Kisor v. Wilkie?
Should Auer (Seminole Rock) deference to an agency's interpretation of its own regulation be overruled, and if not, under what conditions does it apply to the VA's interpretation of "relevant" in 38 C.F.R. § 3.156(c)?
Q3: What rule did the court apply?
Auer/Seminole Rock deference remains but is sharply limited. A court may defer to an agency's interpretation of its own regulation only if: (1) after employing all the traditional tools of construction, the regulation is genuinely ambiguous; (2) the agency's interpretation is reasonable and within the zone of ambiguity; and (3) several context-specific prerequisites are satisfied—namely, the interpretation must be (a) the agency's authoritative or official position (not merely a post hoc litigating stance), (b) within the agency's substantive expertise, and (c) reflect the agency's fair and considered judgment, without causing unfair surprise to regulated parties or upsetting serious reliance interests. Courts must first do their own hard interpretive work, and even if deference is unwarranted, an agency's view may still be considered for its persuasive value under Skidmore.
Q4: What was the court's holding?
The Court declined to overrule Auer deference, but it confined the doctrine to narrow circumstances and vacated the Federal Circuit's judgment for improperly deferring to the VA without first exhausting traditional interpretive tools and without applying the stringent prerequisites for deference. The case was remanded for reconsideration under the clarified framework.
Q5: Why is Kisor v. Wilkie significant?
Kisor preserves Auer deference in name while transforming it in practice. It establishes a demanding multi-step analysis that will often preclude deference: courts must interpret regulations to the hilt, and only genuinely ambiguous provisions, coupled with reasonable, authoritative, expertise-based, and fair agency interpretations, qualify. For litigators, Kisor elevates the importance of detailed textual and contextual arguments and of building records showing whether an agency's position is authoritative and longstanding. For agencies, it incentivizes transparent, consistent, and formal interpretive processes and cautions against ad hoc litigating positions. For students of administrative law, Kisor is essential for understanding modern deference doctrine, the judiciary's interpretive role, and the Court's incremental approach to recalibrating separation-of-powers constraints.
