The Kitáb-i-Aqdas - The Most Holy Book
Index term: term used non-specifically by Bahá'u'lláh, under House(s) of Justice
n42.
the House of Justice
In referring to the House of Justice in the Kitáb-i-Aqdas, Bahá'u'lláh does not always explicitly distinguish between the Universal House of Justice and the Local House of Justice, both of which institutions are ordained in that Book. He usually refers simply to "the House of Justice", leaving open for later clarification the level or levels of the whole institution to which each law would apply.
In a Tablet enumerating the revenues of the local treasury, 'Abdu'l-Bahá includes those inheritances for which there are no heirs, thus indicating that the House of Justice referred to in these passages of the Aqdas relating to inheritance is the local one.
