The Government’s theory [of the scope of the commerce power] would erode those limits, permitting Congress to reach beyond the natural extent of its authority, “everywhere extending the sphere of its activity and drawing all power into its impetuous vortex.”The "hideous monster [with] devouring jaws" — written by Alexander Hamilton in The Federalist No. 33 — appears in Justice Scalia's opinion:
If Congress can reach out and command even those furthest removed from an interstate market to participate in the market, then the Commerce Clause becomes a font of unlimited power, or in Hamilton’s words, “the hideous monster whose devouring jaws... spare neither sex nor age, nor high nor low, nor sacred nor profane.” The Federalist No. 33, p. 202 (C. Rossiter ed. 1961).Many have noted that Scalia (joined by Kennedy, Thomas, and Alito) did not join the Roberts opinion on the Commerce Clause, even though they said basically the same thing about it. Their spirit of resistance shows even through their choice of a different Federalist Paper with a different author and a different metaphor for government's voracious maw.
