Summary

by John Marshall Harlan Chew Heong v. United States — Opinion of the Court

What injustice could be more marked than, by legislative enactment, to recognize the existence of a right by treaty to come within the limits of the United States, and, at the same time, to prescribe, as the only evidence permissible to establish it, the possession of a collector's certificate that could not possibly have been obtained by the person to whom the right belongs?

by John Marshall Harlan Chew Heong v. United States — Opinion of the Court

A treaty that operates of itself without the aid of legislation is equivalent to an act of congress, and while in force constitutes a part of the supreme law of the land. Foster v. Neilson, 2 Pet. 314. Aside from the duty imposed by the constitution to respect treaty stipulations when they become the subject of judicial proceedings, the court cannot be unmindful of the fact that the honor of the government and people of the United States is involved in every inquiry whether rights secured by such stipulations shall be recognized and protected.

by John Marshall Harlan Chew Heong v. United States — Opinion of the Court

In the treaty concluded July 28, 1868, the governments of the United States and China recognized 'the inherent and inalienable right of man to change his home and allegiance, and also the mutual advantage of free migration and emigration of their citizens and subjects, respectively, from one country to the other, for purposes of curiosity, of trade, or as permanent residents.' They therefore joined in reprobating any other than an entirely voluntary emigration for those purposes.
