Note 534 — ARTICLE I (continued 3)

McCarroll v. Dixie Greyhound Lines, 309 U.S. 176, 188-189 (1940). F.D.G. Ribble's State and National Power Over Commerce (Columbia University Press, 1937) is an excellent study both of the Court's formulas and of the arbitral character of its task in this field of Constitutional Law. On the latter point, see especially Chapters X and XII. The late Chief Justice Stone took repeated occasion to stress the "balancing" and "adjusting" role of the Court when applying the commerce clause in relation to State power. See his words in South Carolina State Highway Dept. v. Barnwell Bros., 303 U.S. 177, 184-192 (1938); California v. Thompson, 313 U.S. 109, 113-116 (1941); Parker v. Brown, 317 U.S. 341, 362-363 (1943); and Southern Pacific v. Arizona, 325. U.S. 761, 766-770 (1945). See also Justice Black for the Court in United States v. South-Eastern Underwriters Assoc., 322 U.S. 533, 548-549 (1944).
