In 1873, Baha'u'llah revealed the Kitab-i-Aqdas, the Most Holy Book, His book of laws. Here He established the institution of the House of Justice (bayt al-'adl). The Kitab-i-Aqdas states: 

The Lord hath ordained that in every city a House of Justice (bayt al-'adl) be established wherein shall gather counsellors to the number of Baha [i.e., nine], and should it exceed this number it does not matter ... It behoveth them to be the trusted ones of the Merciful among men and to regard themselves as the guardians appointed of God for all that dwell on earth. It is incumbent on them to take counsel together and to have regard for the interests of the servants of God, for His sake, even as they regard their own interests, and to choose that which is meet and seemly. [10] 

In the same book it is written: 

O ye Men of Justice! (rijal al-'adl) Be ye in the realm of God shepherds unto His sheep and guard them from the ravening wolves that have appeared in disguise, even as ye would guard your own sons. Thus exhorteth you the Counsellor, the Faithful. [11] 

There are other references in the Kitab-i-Aqdas to the House of Justice (bayt al-'adl) or the Place of Justice (maqarr al-'adl) which define its function and fix some of its revenues. In most cases, these references are not specific but refer to the general concept of a House of Justice rather than a particular institution. The Universal House of Justice has explained: 

In the Kitab-i-Aqdas Baha'u'llah ordains both the Universal House of Justice and the Local Houses of Justice. In many of His laws He refers simply to "the House of Justice" leaving open for later decision which level or levels of the whole institution each law would apply to. [12] 

Although the Kitab-i-Aqdas was revealed in 'Akka in 1873, it was withheld for some time by Baha'u'llah before it was distributed to the Baha'is of Iran. [13] 

It appears that it was not until 1878 that the Baha'is of Tehran received copies of the book and began to implement some of its laws in their personal lives. Upon reading the Kitab-i Aqdas, Mirza Asadu'llah Isfahani, a prominent Baha'i teacher living in Tehran, was particularly struck by the command of Baha'u'llah that a House of Justice should be established by the Baha'is in every city. 

Mirza Asadu'llah is an important figure in Baha'i history: he eventually married the sister of 'Abdu'l-Baha's wife; he was (as we shall see) one of the earliest Baha'i teachers sent to America by 'Abdu'l-Baha to instruct the new Western believers and he later accompanied 'Abdu'l-Baha on his travels in Europe. In any case, in 1878 he was the first to undertake the organization of a local House of Justice in Iran. He took the initiative to invite eight other prominent believers to form a body, responding to the laws of the Kitab-i Aqdas, which they referred to as bayt al-'adl (House of Justice) or bayt al-a'zam (the Most Great House). 

The organization of this first House of Justice was kept a secret, even from the believers. However, it met sporadically in the home of Mirza Asadu'llah for a couple of years. After consulting with this body, the prominent Baha'i men who had been invited to attend its meetings would seek to take action as individual Baha'i teachers that would implement its decisions. 

Around 1881, the Tehran House of Justice was reorganized and more members were added. The House adopted a written constitution and pursued its activities with more organization and vigour than before. The constitution mandated, however, that the meetings remain strictly confidential, hidden from the body of the believers. 

This constitution also assumes that the members of the House would all be men (aqayan). Naturally, considering the social conditions in Iran at the time, no other arrangement was possible. 

Some of the minutes of this early House of Justice survive today. It was a gathering of the older and more prominent Baha'i men of Tehran. Meetings were attended by invitation only, and at times included fourteen members or more. Eventually, this meeting came to be called the Consultative Gathering (majlis-i shur), while the house where the body met was referred to as the House of Justice (bayt al-'adl). 

These meetings sought to assist and protect the Baha'is through consultation on various problems. The House in Tehran sent Baha'i teachers to other cities in Iran to organize Houses of Justice there. Again, the decisions of the House were always carried out by individuals, and the consultations remained secret. 

The organization of this body eventually met with some controversy. One important Baha'i teacher, Jamal-i Burujurdi, who later - in the time of 'Abdu'l-Baha - would become a notorious Covenant-breaker, objected strongly to the organization of a House of Justice in Tehran. Because of these objections, the Baha'is involved on the House appealed to Baha'u'llah for guidance. Baha'u'llah replied with a Tablet in which He approved of the House of Justice and strongly upheld the principle of consultation in the Baha'i Faith. [14]
