I have discussed so-called
Skidmore deference on several occasions on this Federal Tax Procedure Blog. I list the principal discussions at the end of this blog. As traditionally formulated,
Skidmore tells a court that an agency interpretation of law not entitled to
Chevron deference can prevail if the interpretation is persuasive. In
Chevron parlance,
Skidmore would involve Chevron-like steps as follows: Step One would require that that the statutory text be ambiguous within the scope of the agency interpretation. That would mean that the agency interpretation must be reasonable within the scope of the ambiguity but there must be other reasonable interpretations (otherwise the statutory text would not be ambiguous). Then at Step Two, the agency interpretation of the ambiguous statutory text would apply if it is "persuasive." But, if the interpretation is persuasive, then no deference is needed to apply it over any other reasonable interpretation that is not persuasive. For this reason, many believe that calling
Skidmore a deference concept is an oxymoron. (See the quote from a recent article at the end of this blog.)
Now, this model of competing reasonable interpretations does raise an interesting issue. In the fact-finding model, where there are competing interpretations of the facts and none prevail over the others, the fact-finder is said to be in a state of equipoise. In the state of equipoise, under the preponderance of the evidence standard (more likely than not), the party bearing the burden of persuasion loses. Of course, most observers of triers of fact (juries or judges) feel that the state of equipoise is rare, so that the assignment of the burden of persuasion is rarely outcome determinative. But, obviously, assigning a winner or loser based on equipoise is outcome determinative when there is a state of equipoise, however rare.
The question I ask is whether the state of equipoise is a useful model in the deference context. Let's assume that the court determines that an agency interpretation is reasonable but is at least one other reasonable interpretation and that none of the interpretations are more "persuasive" than the other. This would mean that the court is in a state of equipoise as to the most persuasive interpretation. Of course, if the agency made that interpretive choice in a
Chevron-entitled regulation,
Chevron would compel that the agency interpretation prevail. But assume that the agency adopts the interpretation of the ambiguous statutory text in subregulatory guidance not entitled to
Chevron deference.
What happens?
Well, if, after applying all available tools of statutory interpretation, the court really is in equipoise as to the most persuasive interpretation, I suppose the court could use the time-honored tie-breaker--flip a coin or some other arbitrary factor to reach a decision. Or alternatively, the Court could default in equipoise to the reasonable agency interpretation. I have not seen any court articulate such a default tie-breaker rule, however. Perhaps there has just been no need to default to such a tie-breaker because, like the fact-finding analog, equipoise is rare.
Justice Gorsuch asserts such positions of equipoise in interpretation are rare, perhaps nonexistent. A good judge, he asserts, applying available interpretive tools should be able to determine that one interpretation is more persuasive than others, without a condition of equipoise between or among the interpretations. In
Kisor v. Wilkie, 588 U.S. ___, 139 S.Ct. 2400 (2019) [Sup Ct Slip Op
here; Google Scholar with S.Ct. pagination
here], Justice Gorsuch in concurring in the judgment (but not accepting the plurality analysis) addressed equipoise as to a regulations interpretation as a basis for
Auer deference, saying (Slip Op. 9-10 and 139 S.Ct., at pp. 2429-30, one footnote omitted):
To be sure, JUSTICE KAGAN paints a very different picture of Auer, asking us to imagine it riding to the rescue only in cases where the scales of justice are evenly balanced between two equally persuasive readings. But that's a fantasy: "If nature knows of such equipoise in legal arguments, the courts at least do not." n31 In the real world the judge uses his traditional interpretive toolkit, full of canons and tie-breaking rules, to reach a decision about the best and fairest reading of the law. Of course, there are close cases and reasonable judges will sometimes disagree. But every day, in courts throughout this country, judges manage with these traditional tools to reach conclusions about the meaning of statutes, rules of procedure, contracts, and the Constitution. Yet when it comes to interpreting federal regulations, Auer displaces this process and requires judges instead to treat the agency's interpretation as controlling even when it is "not . . . the best one."

I think the following from Justice Scalia's remarks captured in the article (a must read in this area,
here) gives a fuller description of his meaning (521):
