Hugo Black,
United States v. Ragen — Opinion of the Court
“ By transforming the question 'Should any deduction have been made?' into 'Was the deduction made in excess of a reasonable allowance?' he can, if the theory accepted below be correct, largely destroy the deterrent effect of a penal statute passed by Congress.We have concluded, however, that the ground of decision below is untenable. The mere fact that a penal statute is so framed as to require a jury upon occasion to determine a question of reasonableness is not sufficient to make it too vague to afford a practical guide to permissible conduct. ”
