§ 350.Legally protected health activities.

CPLR 350 is a single-section article, added at the end of 2025, that answers a choice-of-law question rather than a service or jurisdiction question. When a case heard in a New York court relates to legally protected health activity, a term defined in Criminal Procedure Law 570.17, New York law governs. The section overrides any general or special law, any common-law rule, and any conflict-of-law principle that might otherwise point a court toward applying another state's law.

Ordinarily, a New York court deciding which state's law applies to a dispute weighs factors like where the parties are located, where the conduct occurred, and what law the parties may have chosen for themselves. Section 350 replaces that balancing test, for this category of case, with a fixed rule: New York law applies. A choice-of-law clause pointing to another state, or a common-law doctrine that would otherwise favor another state's law, gives way.

The section reaches only cases and controversies heard in a New York court. It's part of a broader legislative package enacted in December 2025 responding to other states' attempts to use their own law, or their courts' process, to reach conduct connected to reproductive health care and gender-affirming care that's lawful in New York. Section 350 supplies the choice-of-law backbone for that package inside the CPLR itself, while the definition of what activity is protected lives in the Criminal Procedure Law.
