The Baha'i Administrative Order Working in groups effectively requires some kind of organization. Therefore, Baha'u'llah provided for an administrative order at the local, national and international levels to guide the Baha'i World after His passing. Houses of Justice The Baha'i Administrative Order is organized into Houses of Justice of nine members each. The Local House of Justice is elected by the believers in the local community. The National House of Justice is elected by delegates at a national convention. The Universal House of Justice, the supreme international body in the administrative order, is elected by the National Houses at a world convention. The Universal House of Justice is authorized to rule on any aspect of the Faith not expressly revealed in Baha'i scriptures. This hierarchy of elected representative bodies constitutes the administrative wing of the Baha'i Order.
