80.O ye Men of Justice!   ¶52
It has been elucidated in the writings of ‘Abdu’l-Bahá1 and Shoghi Effendi2 that, while the membership of the Universal House of Justice is confined to men, both women and men are eligible for election to Secondary and Local Houses of Justice (currently designated as National and Local Spiritual Assemblies).
