Byron White, Weeds v. United States — Opinion of the Court
“ I see no unconstitutional lack of definiteness in the prohibition of a conspiracy to exact excessive prices for necessaries. In the absence of a statutory definition of, or method of determining, standard prices, with which to compare the prices alleged to be excessive, the natural standard, according to which this provision of the act ought to be interpreted, is that adopted in the ordinary transactions of men, and adhered to by the common law time out of mind-the standard of fair market value ”
