Stephen Johnson Field,
Soon Hing v. Crowley — Opinion of the Court
“ The specific regulations for one kind of business, which may be necessary for the protection of the public, can never be the just ground of complaint because like restrictions are not imposed upon other business of a different kind. The discriminations which are open to objection are those where persons engaged in the same business are subjected to different restrictions, or are held entitled to different privileges under the same conditions. It is only then that the discrimination can be said to impair that equal right which all can claim in the enforcement of the laws. ”
