The first respondent (Sybeth Musengezi) instituted proceedings under HC5687/21 challenging the ascendancy of President Emmerson Mnangagwa to the presidency of ZANU PF following "Operation Restore Legacy" in November 2017. He claimed that the special session of the Central Committee convened on 19 November 2017 was ultra vires the party's constitution and sought to set aside the resolutions. The first applicant is a trust registered in Zimbabwe consisting of several non-governmental organisations aimed at achieving democracy, rule of law and constitutionalism. The second applicant is a private citizen and trustee of the first applicant, who is also a member of ZANU PF. The applicants sought to be joined to the pending proceedings, alleging that the first respondent fraudulently assumed membership of ZANU PF and that they have a direct and substantial interest in the outcome. The first respondent opposed the joinder, arguing that the trust was improperly constituted, that the applicants lacked substantial interest and locus standi, and that the party's interests were already sufficiently protected.
