WHY ENUMERATION MATTERS
Richard Primus*
The maxim that the federal government is a government of enumerated powers can be understood as a “continuity tender”: not a principle with practical
consequences for governance, but a ritual statement with which practitioners
identify themselves with a history from which they descend. This interpretation makes sense of the longstanding paradox whereby courts recite the enumeration principle but give it virtually no practical effect. On this
understanding, the enumerated-powers maxim is analogous to the clause that
Parliament still uses to open enacted statutes: “Be it enacted by the Queen’s
most Excellent Majesty.” That text might imply that the Queen is a source of
legislative authority, but there is no practical sense in which legislation depends on her. Similarly, it might misunderstand the American system to think
that Congress is in practice—or ought, in practice, to be—limited by its enumerated powers (as opposed to the political process or affirmative constitutional prohibitions), even though we continue to repeat the traditional
statement. One important difference between the two cases, however, is that in
the British system there is no controversy about whether the Queen should
enjoy legislative power. In the American system, where there is serious disagreement about whether the enumerated powers of Congress must be limiting,
it is necessary to bring the ritual-continuity aspect of the maxim more clearly
into view, thus explaining why we could be attached to the maxim even if it
need not do important practical work in the operations of governance.

Introduction
The federal government is a government of enumerated powers. As a
matter of official theory, the enumeration of those powers limits what Congress can do.1 As every lawyer knows, however, Congress can in practice use
its enumerated powers to regulate pretty much anything that a state could
regulate.2 The judiciary’s few decisions striking down federal action as exceeding Congress’s enumerated powers have not as a practical matter imposed meaningful constraints upon Congress’s legislative jurisdiction,3 and
there is no compelling evidence that Congress has enforced enumerationbased limitations on itself, declining to enact laws that it otherwise favored
because it believed its enumerated powers insufficient for their enactment.4
To be sure, the Constitution does and should limit what Congress can do.
Federal legislation is limited by the structure of the government and its institutions, and federal legislation is also limited by affirmative prohibitions like
1. See, e.g., Bond v. United States, 134 S. Ct. 2077, 2086 (2014) (“In our federal system,
the National Government possesses only limited powers; the States and the people retain the
remainder.”).
2. See Pamela S. Karlan, The Supreme Court, 2011 Term—Foreword: Democracy and Disdain, 126 Harv. L. Rev. 1, 42–43 (2012) (discussing the broad applicability of the Commerce
Clause power announced in Wickard v. Filburn, 317 U.S. 111 (1942)); Gil Seinfeld, Article I,
Article III, and the Limits of Enumeration, 108 Mich. L. Rev. 1389, 1391 (2010) (identifying
this view as “the standard story”).
3. In United States v. Lopez, 514 U.S. 549, 567–68 (1995), and United States v. Morrison,
529 U.S. 598, 617–19 (2000), the Supreme Court did strike down federal statutes on internallimit grounds. But the internal limit articulated in those cases does not, in practice, prevent
Congress from pursuing any regulatory agenda that it has the political will to implement. See
infra Section II.A.
4. It is not hard to find examples of members of Congress arguing against bills on these
grounds. See, e.g., 156 Cong. Rec. 4112, 4117–18, 4134, 4137 (2010) (recording various representatives’ arguments that the Affordable Care Act would be unconstitutional because it exceeds Congress’s powers). It is just hard to find examples of that argument winning out. To be
sure, Congress should, and routinely does, consider whether a particular policy need should be
addressed federally rather than locally (or cooperatively), and it often decides against federal
regulation. See, e.g., 146 Cong. Rec. 16,059 (2000) (characterizing the Innocent Chil (...truncated)
