The U.S. Supreme Court’s unanimous decision in Galette v. New Jersey Transit Corp. clarifies when a state-created entity can claim interstate sovereign immunity — i.e., immunity from being sued in another state’s courts. The Court held that NJ Transit is not an “arm of the State” of New Jersey and therefore can be sued outside New Jersey for alleged negligence.

What Happened

New Jersey created NJ Transit in 1979 as a “body corporate and politic,” giving it traditional corporate powers such as the ability to sue and be sued, enter contracts, hold property, and incur debt. Two separate bus accidents — one in Manhattan and one in Philadelphia — led to personal-injury suits filed in New York and Pennsylvania. New York’s highest court allowed the suit to proceed; Pennsylvania’s highest court dismissed on immunity grounds. The Supreme Court took the cases to resolve that conflict.

The Court’s Framework (And Why It Matters)

Justice Sotomayor’s opinion refocuses the “arm-of-the-state” inquiry on a more formal, structure-first question: Did the state create a legally separate entity that is responsible for its own judgments?

Three points drove the result:

1. Separate legal personhood. NJ Transit’s enabling statute uses corporate form and grants classic corporate powers (including “sue and be sued”), which the Court treated as strong evidence of separateness.
2. No formal state liability. New Jersey law provides that NJ Transit’s debts and liabilities are not debts or liabilities of the State and that expenses are payable from the corporation’s own funds.
3. State oversight isn’t enough. Even though New Jersey exercises meaningful control (appointments, vetoes, oversight), that control did not overcome the entity’s separate corporate status and responsibility for its own judgments.

The Court also rejected arguments that immunity should turn on public function or practical reliance on state funding, warning that those approaches invite inconsistent outcomes as funding levels and operational realities change.

“Although the Court’s arm-of-the-State cases have accounted for various considerations over time, those precedents have consistently, and predominantly, examined whether the State structured the entity as a legally separate entity liable for its own judgment.”

Key Takeaways

For companies that contract with, compete against, insure, or litigate against state-created entities (think transit authorities, public benefit corporations, university systems, port authorities), Galette offers a clearer playbook:

• Expect more out-of-state litigation exposure for state-created corporations that operate across borders — particularly where statutes emphasize corporate form and “sue-and-be-sued” capacity.
• Statutory structure will lead the analysis. In diligence, disputes, and risk assessment, focus first on the entity’s enabling act: corporate powers, ability to contract and hold property, and — most importantly — who pays judgments.
• Contracting and claims strategy should adjust. Venue, forum-selection clauses, indemnities, insurance requirements, and limitations of liability matter more when the counterparty cannot reliably invoke sovereign immunity outside its home state.
• Watch for legislative responses. As the opinion notes, states can legislatively restructure entities (including formal assumption of liabilities) if they want different immunity outcomes going forward.
