The U.S. Supreme Court on Sept. 19 formally blocked a trial in New York state court related to an upcoming high court case over New Jersey Transit’s potential liability for injuries caused outside its home state.

The state trial will have to wait until the U.S. Supreme Court has heard and decided New Jersey Transit Corp. v. Colt, the nation’s highest court ruled in an unsigned order. The high court’s hearing in the case has not yet been scheduled, but is expected to take place during the new term that begins in October.

In the case at hand, Jeffrey Colt sued New Jersey Transit in 2017 in New York state court, claiming that a transit agency bus struck him in New York City, according to the agency’s U.S. Supreme Court petition.

On Sept. 12, the U.S. Supreme Court issued an administrative stay temporarily halting the New York state trial that gave rise to the high court appeal. The trial had been scheduled to begin on Sept. 15, but on Sept. 11, New Jersey Transit asked the high court to block the trial. An administrative stay gave the justices more time to fully consider the emergency application.

The latest ruling came as the U.S. Supreme Court prepares to hear oral argument in New Jersey Transit Corp. v. Colt after granting the transit agency’s petition for certiorari, or review, on July 3. The high court ordered that the appeal be heard together with a related case from Pennsylvania known as Galette v. New Jersey Transit Corp.

New Jersey Transit is being sued in state courts in New York and Pennsylvania after its buses allegedly struck people while operating outside the Garden State. Although the transit agency operates buses, trains, and light rail primarily in its home state, its service extends to the Philadelphia and New York metropolitan areas.

The legal issue is whether New Jersey’s public transit system may be sued for accidents that take place outside of New Jersey.

The U.S. Supreme Court noted in its unsigned Sept. 19 order that it had already agreed to hear oral argument in the case on the sovereign immunity issue.

Sovereign immunity is a legal doctrine that prevents governments from being sued unless they consent to being sued. The sovereign immunity of U.S. states is enshrined in the 11th Amendment to the U.S. Constitution.

In the yet-unscheduled oral argument, the U.S. Supreme Court will review state court decisions on whether the New Jersey entity counts as an arm of that state, and thereby enjoys sovereign immunity from lawsuits in other states’ courts.

The New York Court of Appeals, the state’s highest court, in November 2024 allowed the case to proceed in the state court system.

That court found that maintaining the “action against defendant New Jersey Transit Corporation in [New York] courts would not offend New Jersey’s sovereign dignity” and held that the defendants were “not entitled to invoke a sovereign immunity defense.”

Sovereign dignity refers to a state’s right to be treated with respect and not to have parties outside its borders interfere with its internal affairs.

The U.S. Supreme Court said in the new order that the stalled trial before the New York County division of the New York Supreme Court would be barred if the justices were to rule that New Jersey Transit enjoys sovereign immunity from suit.

However, the respondents in the case did not identify any “tangible irreparable harm they would face if the trial were delayed until after this Court decides the pending case,” the order said.

The U.S. Supreme Court stayed the New York trial until it hears and rules on New Jersey Transit Corp. v. Colt, and its decision has taken effect. No justices dissented.

Michael Symons, press secretary to New Jersey Solicitor General Jeremy Feigenbaum, declined to comment.
