The Universal House of Justice is the supreme governing institution of the Bahá'í Faith. It is a legislative institution with the authority to supplement and apply the laws of Bahá'u'lláh, the founder of the Bahá'í Faith, and exercises a judicial function as the highest appellate institution in the Bahá'í administration. The institution was defined in the writings of Bahá'u'lláh and `Abdu'l-Bahá, Bahá'u'lláh's successor, and was officially established in 1963.
