May 30. On this date in 1930, Shoghi Effendi addressed a letter to an NSA stating "To accept the Cause without the administration is like to accept the teachings without acknowledging the divine station of Bahá'u'lláh. To be a Bahá'í is to accept the Cause in its entirety. To take exception to one basic principle is to deny the authority and sovereignty of Bahá'u'lláh, and therefore is to deny the Cause."

(Letter to a National Spiritual Assembly, 30 May 1930)

In 1951, Shoghi Effendi, as Guardian, appointed members to the International Bahá’í Council, naming Mason Remey as the Council's President and describing it as an embryonic international House of Justice.
When Shoghi Effendi passed away in 1957 without having appointed a successor Guardian, as confirmed by a "Unanimous Proclamation of the 27 Hands of the Cause of God", the Hands of the Cause of God elected from among their own nine individuals who would serve as Custodians to help lead the transition of the International Bahá’í Council, into the Universal House of Justice.
In 1961 the International Bahá’í Council was changed to an elected body, with members of all National Spiritual Assemblies voting.
In 1963, the first Universal House of Justice was elected, and its members are elected every five years by members of each Bahá'í National Spiritual Assembly in the world. In practice, the Bahá’í electoral system most closely resembles council democracy as it still exists in Cuba, wherein individuals elect Local Spiritual Assemblies, who then elect National Spiritual Assemblies, who then elect the Universal House of Justice. With no politicking or partisanship allowed, there is little turnover in leadership and Universal House of Justice members almost invariably serve until retirement or death. New members are currently generally elected from the appointed institutions of the Bahá’í administration, particularly the International Teaching Centre. In fact, all of the current members of the Universal House of Justice previously served as members of the International Teaching Centre. In council democracies, these career bureaucrats were known as the nomenklatura.
With the eventual passing of the individual Hands of the Cause of God appointed by Shoghi Effendi and without a Guardian to appoint additional Hands, the Universal House of Justice saw the need for developing an institution for the purpose of performing the Hands' function of protection and propagation of the Faith.
In 1968 the Continental Board of Counselors was formed. The Counselors appoint Auxiliaries collectively referred to as Auxiliary Boards in smaller regional areas, who in turn appoint their own Assistants to work in localities.
Auxiliary Board Members for Protection are charged with watching over the security of the Bahá’í Faith, and Auxiliary Board Members for Propagation are responsible for working with the grassroots on the global Plans established by the Universal House of Justice. Originally, members of the Auxiliary Boards were appointed by and served under the Hands of the Cause of God who directed their efforts worldwide. The first members of the Auxiliary Boards were appointed in 1954, and they were divided into five distinct geographical regions
In 1973 the administrative branch called the Institution of the Counselors was formed. Also in 1973, the International Teaching Centre was first formed by the Universal House of Justice, and originally consisted of the 17 Hands of the Cause still living at that time, plus three Counsellor members. The number of Counsellor members was raised to four in 1979, to seven in 1983, and finally to the current nine in 1988. The Counsellor members of the International Teaching Centre are appointed by the Universal House of Justice to five-year terms that begin shortly after the International Convention and election of the Universal House of Justice.
