Northern Mariana Islands
Capital: Saipan · Population: 47,329
Constitutional Basis
The CNMI became a U.S. commonwealth in 1978 through a Covenant with the United States. It is the only territory that negotiated its relationship with the U.S. The CNMI adopted its own constitution in 1978, which has been amended multiple times.
Legal System
The CNMI operates under a common law system established by the Covenant to Establish a Commonwealth (1975). Its constitution uniquely restricts land ownership to persons of NMI descent. Federal immigration law was extended to the CNMI in 2009, replacing the territory's own immigration system.
Court Structure
The CNMI judiciary consists of the Supreme Court of the CNMI, the Superior Court (trial court of general jurisdiction), and the Commonwealth Courts (limited jurisdiction). Federal cases are handled by the U.S. District Court for the NMI, with appeals to the Ninth Circuit.
