The applicant, George Musanhu, is the brother of the late Aube Musanhu who died intestate in August 2006. The applicant sought to set aside a document titled "Confirmation of Customary Law Marriage Form" which confirmed the existence of a customary law union between the late Aube Musanhu and the first respondent, Chipo Munguma. The document was directed to the Director of Pensions and was confirmed by two relatives (Simon Musanhu and Joseph Musanhu) before Provincial Magistrate J. Mzinyathi. The applicant's position was that the first respondent was merely involved in an adulterous relationship with Aube during the currency of Aube's civil monogamous marriage to Patricia Chifuro, and that the confirmation was obtained through material misrepresentations. The late Aube left behind a sizeable estate including a resettlement farm and a house in Masvingo. The applicant argued that documentation relating to Aube's estate registered under DR 1179/10 showed he was a widower at the time of death (Patricia having died in October 2002), and that the first respondent fraudulently registered a parallel estate. The first respondent maintained she entered into an unregistered customary law union with Aube after Patricia's death and that the applicant was driven by greed to unlawfully wrest the estate from her.
The matter was referred to trial in terms of Rule 46(10)(b) of the High Court Rules, 2021, specifically for determination of whether the first respondent is the surviving spouse of the late Aube Musanhu who died on 7 August 2006. The papers filed of record were to stand as pleadings with no further pleadings required save as directed by the court. The court was to provide further directions as required by the parties. Costs were ordered to be in the cause.
For the defense of res judicata to succeed, there must have been prior litigation between the parties resulting in a final judgment or decision with final effect based on the merits of the point in issue. A magistrate's decision declining to exercise jurisdiction, and an appeal that is withdrawn before arguments are presented, do not constitute decisions on the merits that would render subsequent proceedings res judicata. The requirements for res judicata are: idem actor (same parties), idem reus (same defendant), eadem res (same subject matter), and eadem causa petendi (same cause of action). Where material disputes of fact arise in application proceedings that cannot be resolved on affidavit evidence alone, and where it would not be equitable to dismiss the application, the court may exercise its discretion under Rule 46(10)(b) to refer the matter to trial for determination of the disputed factual issues.
The court observed that the "Confirmation of Customary Law Marriage Form" directed to the Director of Pensions is a rudimentary attempt to establish the identity of persons who might have been customarily married to a deceased person, and that it is doubtful whether the form has any relevance outside the scope of disbursement of pension emoluments. The court noted that the form represents a quasi-judicial function performed by the magistrate (or potentially by a district administrator or chief). The court commented on the "internecine legal battles waged between the applicant and first respondent which battles are strewn across literally the entire spectrum of Zimbabwe's Court system" all having one underlying common denominator: the legitimacy of the second respondent's claim to being the surviving spouse of the late Aube Musanhu. The court remarked that the pitched legal battles were not surprising given that the late Aube left behind a sizeable estate, and the triumphant party would assume the right to that estate either as administrator or beneficiary or both.
This case is significant for its comprehensive treatment of the defense of res judicata in Zimbabwean law, particularly clarifying that a decision declining jurisdiction is not a decision on the merits that would bar subsequent litigation. The case also demonstrates the court's discretion in managing application proceedings where material disputes of fact arise, particularly the option of referring matters to trial under Rule 46(10)(b) of the High Court Rules. The case highlights procedural issues in confirming customary law marriages for purposes of pension benefits and the quasi-judicial nature of such confirmations. It illustrates the challenges in succession matters involving unregistered customary law unions and the importance of proper evidence in establishing marital status for succession purposes.
