“The infallibility of the Universal House of Justice…has not been made dependent upon the presence in its membership of the Guardian of the Cause.”

The infallibility of the Universal House of Justice, operating within its ordained sphere, has not been made dependent upon the presence in its membership of the Guardian of the Cause. Although in the realm of interpretation the Guardian’s pronouncements are always binding, in the area of the Guardian’s participation in legislation it is always the decision of the House itself which must prevail. This is supported by the words of the Guardian: “The interpretation of the Guardian, functioning within his own sphere, is as authoritative and binding as the enactments of the International House of Justice, whose exclusive right and prerogative is to pronounce upon and deliver the final judgment on such laws and ordinances as Bahá’u’lláh has not expressly revealed. Neither can, nor will ever, infringe upon the sacred and prescribed domain of the other. Neither will seek to curtail the specific and undoubted authority with which both have been divinely invested.

“Though the Guardian of the Faith has been made the permanent head of so august a body he can never, even temporarily, assume the right of exclusive legislation. He cannot override the decision of the majority of his fellow-members, but is bound to insist upon a reconsideration by them of any enactment he conscientiously believes to conflict with the meaning and to depart from the spirit of Bahá’u’lláh’s revealed utterances.”

However, quite apart from his function as a member and sacred head for life of the Universal House of Justice, the Guardian, functioning within his own sphere, had the right and duty “to define the sphere of the legislative action” of the Universal House of Justice. In other words, he had the authority to state whether a matter was or was not already covered by the Sacred Texts and therefore whether it was within the authority of the Universal House of Justice to legislate upon it. No other person, apart from the Guardian, has the right or authority to make such definitions.
