New York v. O'NEILL

Background

An Illinois citizen was visiting Florida for a convention when a New York judge filed a certificate asking Florida to produce him to testify before a New York grand jury. Florida’s "Uniform Law to Secure the Attendance of Witnesses"—adopted by forty-two States and Puerto Rico—allows one State to file such a certificate in another State, treats the certificate as prima facie proof, and requires a local hearing where the witness is entitled to counsel and the court decides materiality, hardship, immunity, and travel pay.

Reasoning

The Court had to decide whether that reciprocal law is consistent with the Constitution. The majority said the statute is presumptively constitutional, serves cooperative state interests, and does not discriminate against nonresidents under Article IV or violate the Fourteenth Amendment’s protections in the way claimed. The Court accepted that the forwarding State has personal jurisdiction over a person found within its borders, upheld the statute’s hearing protections, and reversed the Florida Supreme Court’s facial invalidation. The Florida court’s concern about absence of a statutory bail provision was left undecided.

Real world impact

The decision allows the Uniform Act procedures to be used in criminal matters across the forty-two enacting States and Puerto Rico, making it easier for prosecutors and grand juries to secure out-of-state witnesses. It affects nonresident witnesses who may be summoned or temporarily taken into custody and requires states to follow the statute’s hearing and payment rules. The ruling is a facial decision; challenges to how the law is carried out in individual cases may still be litigated.

Dissents or concurrances

A dissenting opinion argued that freedom to enter and leave States is a basic right of national citizenship, that States lack power to forcibly send innocent citizens across state lines, and that the Court should have left the Florida Supreme Court’s judgment in place.
