Last week, I participated in a panel at the ABA Tax Section
Fall Meeting in Dallas. The panel was offered by the ABA Tax Section Teaching
Taxation Section. The program was titled “Classification of Tax Regulations and
the APA.” The panel participants were Les Book (moderator), Kristin Hickman,
Gil Rothenberg, and me. The program dealt in part with some issues that
Professor Hickman and I have engaged in the past. On those issues, Hickman and
I continue to engage without agreement.
I say "without agreement," but in fact Hickman and I did agree
(i) on the starting point that, at the enactment of the APA in 1946, the APA
permitted both legislative rules (must be notice and comment regulations) and
interpretive rules (including, although not required, notice and comment
regulations such as Treasury used for interpretive rules adopted as regulations)
and (ii) that for well after the APA, the category of interpretive notice and
comment regulations was alive and well, without controversy. Our point of continuing
disagreement is whether something has changed that original meaning of the APA,
so that notice and comment regulations that do no more than interpret ambiguous
statutory text no longer exist but are now legislative regulations. That
disagreement is not the focus of this posting but may underly some of the
analysis in this posting.
In the panel discussion, I repeated my recent claim that Chevron
deference is inapplicable if the agency interpretation is the best interpretation.
The corollary to this is that Chevron’s domain in an outcome
determinative sense involves only deference to “not best” agency interpretations. We
only touched on that issue lightly in the panel, but one panelist questioned
whether "best interpretation" was a meaningful concept. (Added 10/25/22 11:00am: On Chevron's domain as limited to not best interpretations, see e.g., Nat’l Cable & Telecomms. Ass’n v. Brand X Internet Servs., 545 U.S. 967, 980 (2005) (“Chevron requires a federal court to accept the agency’s construction of the statute, even if the agency’s reading differs from what the court believes is the best statutory interpretation.”).)
I thought it might be helpful to say further what I mean by “best
interpretation.” The best (or most
persuasive) interpretation is the interpretation which the court would apply based
solely on interpretive tools in the absence of an agency interpretation or, if
there is an agency interpretation, in the absence of Chevron deference. The
court’s job in statutory interpretation is to determine and apply the best
interpretation of the statute to the facts before the court. (BTW, it is
important to note that courts cannot legislate, so courts’ exercise of
interpreting a statute to determine the best interpretation is not legislative. See Is Statutory Interpretation a Legislative Act When Agencies Do It But Not When Courts Do It? (Federal Tax Procedure Blog 4/8/22; 10/23/22), here.).
If the agency interpretation is that best interpretation,
the court applies that interpretation because it is the best interpretation and
not because it is deferring to the agency interpretation. Of course, in
determining the best, most persuasive interpretation, the court should consider
respectfully the agency interpretation. Skidmore v. Swift & Co., 323
U.S. 134, 140 (1944) (Skidmore respect is not deference (although
frequently mislabeled as deference) and applies at Chevron Step One as
well as in generally determining the most persuasive interpretation.) See Really, Skidmore "Deference?" (Federal Tax Procedure Blog 5/31/20; 2/14/21), here. Deference—real
deference--is only outcome determinative if the court invokes Chevron to
apply a “not best” interpretation over the court’s own best interpretation.
That best interpretation concept is simple and, I think,
irrefutably true. There will always be a “best interpretation” so
defined because, in the absence of an agency interpretation, it is the
interpretation the court would apply to decide the case. In deciding whether or
not to apply Chevron deference to an agency interpretation, a court will
have to know what the best interpretation is (i.e., what the court would do
without deference to the agency interpretation). How else could a court determine
whether an agency interpretation is “reasonable” or “permissible” even though
not best (the requirement for Chevron deference)?
