Yesterday and today, I have been thinking about an article that implicates some of the interpretive issues I have been writing on post-Loper Bright. The article is: John O. McGinnis & Mike Rappaport, Originalism’s Better Meaning (Law & Liberty 8/13/26), here. Although developed in the context of constitutional interpretation and originalism, the article makes some points that seem to me applicable to statutory interpretation more broadly than the originalism spin.
First, the authors define the difference between interpretation and construction:
Interpretation is the process of determining the meaning of a constitutional provision. Construction begins only when that meaning is deemed indeterminate—that is, when it is thought to run out—and the decision must be made on grounds other than the provision’s original meaning.
I would restate that for statutory interpretation as follows (with changes in bold):
Statutory interpretation is the process of determining the meaning of a statutory provision. Statutory construction begins only when that meaning is deemed indeterminate—that is, when it is thought to run out—and the decision must be made on grounds other than the provision’s meaning as determined by statutory interpretation.
In these constructs, Chevron deference was construction rather than interpretation because it applied only when the meaning could not be determined and applied as a default rule to resolve cases before the courts without regard to the indeterminate meaning of the statute.
One interesting construct the authors deploy in the article is the “51-49 rule” which permits the “best” interpretation to be determined by the preponderance of the evidence standard (applying fact-finding concepts to a state of statutory interpretive ambiguity). In this construct, interpretation of a constitution (or statute) requires a confidence level for an interpretation to be at least 51%. The construction zone is between 50.9999% and 49.0001% where some default rule is required to resolve cases.
(Caveat: I don’t think that is a realistic range in statutory interpretation (or fact-finding for that matter); can anyone meaningfully distinguish between an interpretation that is 49.9% and one that is 50.1%?; but let’s just accept that construct for now; for my discussion of such ranges in valuation context, see John A. Townsend, Burden of Proof in Tax Cases: Valuation and Ranges—An Update, 73 Tax Lawyer 389 (2020).)
