At whatever time all the beloved of God in each country appoint their delegates, and these in turn elect their representatives, and these representatives elect a body, that body shall be regarded as the Supreme Baytu’l-’Adl (Universal House of Justice). 
(‘Abdu’l-Baha, from a Tablet, quoted by Shoghi Effendi in a letter dated May 12, 1925; ‘Baha’i Administration’)
