The High Council existed within the framework of the New Republic and served as an important entity. One of its responsibilities involved accepting updates from the New Republic Observers, a governmental organization tasked with looking into possible governmental misconduct. Furthermore, it wielded considerable influence over diplomatic affairs and military deployments.
Composed of prominent figures from the New Republic Senate, including the Chief of State, the High Council convened on raised, curved platforms located at the Senate's far end. Prominent members of the High Council during the Caamas Document Crisis were Ponc Gavrisom, Leia Organa Solo, Borsk Fey'lya, and Sien Siev. In that period, the majority of the High Council was against the continued relationship with the Smugglers' Alliance, and at least three council members adopted a position against the Bothan species.
It is conceivable that it served as a partial model for the subsequent High Council within the Galactic Alliance.
