Rufus Wheeler Peckham, Gundling v. Chicago — Opinion of the Court
“ The business is more easily subjected to the operation of the power to regulate where a license is imposed for following the same, while the revenue obtained on account of the license is none the less legal because the ordinance which authorized it fulfils the two functions, one a regulating and the other a revenue function. So long as the state law authorizes both regulation and taxation, it is enough, and the enforcement of the ordinance violates no provision of the Federal Constitution. ”
