Shaughnessy v. United States Ex Rel. Mezei

Background

An immigrant who had lived in the United States for many years left in 1948 and returned in 1950 with a visa. Immigration officials temporarily held him on Ellis Island and, after reviewing confidential information, the Attorney General ordered him permanently excluded on national-security grounds. Other countries refused to admit him back, and lower courts ordered his temporary admission to the United States on bond while arrangements for departure were sought.

Reasoning

The core question was whether keeping him off U.S. soil without a public hearing became unlawful detention that courts could cure by admitting him on bond. The majority held that, under emergency immigration law and long-standing precedents, an entrant excluded at the border (even if sheltered on Ellis Island) may be barred without a public hearing when the exclusion rests on confidential security information. His temporary refuge ashore did not count as entry, his long absence made him an entering alien again, and courts may not force disclosure of the secret evidence or override the Attorney General’s exclusion.

Real world impact

The ruling means the Government can exclude and keep from the mainland people judged dangerous on confidential security grounds, even when other countries will not accept them. Courts are limited in ordering temporary admission on bond in such cases. The decision leaves persons stranded abroad or at ports of entry dependent on executive and legislative choices rather than on judicial bail relief.

Dissents or concurrances

Two Justices dissented, arguing that indefinite confinement of a long-time resident without an open hearing violates basic due process and risks unchecked executive power.
