Hines v. Davidowitz

[*59] Mr. Justice Black delivered the opinion of the Court.

This case involves the validity of an Alien Registration Act adopted by the Commonwealth of Pennsylvania.[1] The Act, passed in 1939, requires every alien 18 years or over, with certain exceptions,[2] to register once each year ; provide such information as is required by the statute, plus any “other information and details” that the Department of Labor and Industry may direct; pay $1 as an annual registration fee; receive an alien identification card and carry it at all times; show the card whenever it may be demanded by any police officer or any agent of the Department of Labor and Industry; and exhibit the card as a condition precedent to registering a motor vehicle in his name or obtaining a license to operate one. The Department of Labor and Industry is charged with the duties of classifying the registrations for “the purpose of ready reference,” and furnishing a copy of the classification to the Pennsylvania Motor Police. Nonexempt aliens who fail to register are subject to a fine of not [*60] more than $100 or' imprisonment for not more than 60 days, or both. For failure to carry an identification card or for failure to show it upon proper demand, the punishment is a fine of not more than $10, or imprisonment for not more than 10 days, or both.

A three-judge District Court enjoined enforcement of the Act, holding that it denied aliens equal protection of the laws, and that it encroached upon legislative powers constitutionally vested in the federal government.[3] It is that judgment we are here called upon to review.[4] But in 1940, after the court had held the Pennsylvania Act invalid, Congress enacted a federal Alien Registration Act.[5] We must therefore pass upon the state Act in the light of the Congressional Act.[6]
