have the regard for all peoples and safe-guard their honour. Later, ʻAbdu'l-Bahá, Baháʼu'lláh's son and successor, in his Will and Testament, elaborated on its functioning, its composition and outlined the method for its election. He wrote that the Universal House of Justice would be under Baháʼu'lláh's protection, that it would be freed of error, and that obedience to it would be obligatory. ʻAbdu'l-Bahá first used the term "Universal House of Justice" to distinguish the supreme body from those local 'Houses of Justice' to be established in each community, and the secondary 'Houses of Justice' (current Baháʼí national spiritual assemblies). He also stated that the institution's decisions could be by majority vote, but that unanimous decisions were preferred, and that it would be elected by the members of the secondary Houses of Justice. He also confirmed Baháʼu'lláh's statements that although women and men are spiritually equal, membership on the Universal House of Justice would be confined to men, and that the wisdom behind this decision would become apparent in the future (see Baháʼí Faith and gender equality). While both ʻAbdu'l-Bahá and Shoghi Effendi, heads of the religion after Baháʼu'lláh, considered establishing the Universal House of Justice, they both declined to do so. Shoghi Effendi's reason was due to his belief in the weakness of the existing Baháʼí institutions — there were a very limited number of national spiritual assemblies and local spiritual assemblies. Thus during his lifetime, Shoghi Effendi prepared for the election of the Universal House of Justice, by establishing a strong administrative structure at the local and national levels. In 1951 when there were 9 National Spiritual Assemblies, Shoghi Effendi appointed members to the International Baháʼí Council, and described it as an embryonic international House of Justice. After Shoghi Effendi's unexpected death in 1957, the Hands of the Cause directed the affairs of the religion and announced that the election of the Universal House of Justice would occur in 1963 at the end of the Ten Year Crusade, an international teaching plan instituted by Shoghi Effendi. In 1961 the International Baháʼí Council was changed to an elected body, with members of all National Spiritual Assemblies voting for its members. Then in April 1963, the first Universal House of Justice was elected, six years after the passing of Shoghi Effendi, by 56 National Spiritual Assemblies. The date of the election coincided with the completion of the Ten Year Crusade and
