The Nanticoke Lenni-Lenape Tribal Nation, which claims its history has been rewritten in New Jersey in recent years, is a recognized American Indian tribe, a state appeals court has ruled.

The tribe said in its lawsuit that the state violated its rights under the state constitution and common law when, in 2012, the Attorney General’s Office told the federal government that the state did not recognize the Nanticoke Lenni-Lenape as a tribal nation. It claimed that decision would harm its ability to conduct business and receive government grants and contracts.
