In July 2014, the plaintiff entered into an agreement of sale with the second and third defendants (represented by the fourth defendant via power of attorney) for the sale of Lot Number 17 Weirmouth Smallholdings, measuring 7.2769 hectares. The first defendant facilitated the sale as an estate agent. In February 2016, the second and third defendants entered into another sale agreement over the same property with the fifth defendant, also facilitated by the first defendant, after alleged cancellation of the first agreement. The plaintiff alleged he was never notified of the cancellation and that the second sale was fraudulent and invalid. The plaintiff had previously sought a declaratur in the Mutare High Court to nullify the second sale, but his application was dismissed. His application for condonation of late noting of an appeal against that judgment was also dismissed by the Supreme Court. Despite these adverse rulings, the plaintiff instituted fresh proceedings seeking essentially the same relief.
The plaintiff's claim was dismissed with costs on an attorney and client scale against the plaintiff in favour of the defendants.
Where a matter has been finally and definitively determined by a competent court involving the same parties, same subject matter and same cause of action, the doctrine of res judicata operates as an absolute bar to the re-institution of proceedings seeking the same relief. The doctrine applies not only to the ratio decidendi itself but also to issues necessarily determined as part of the ratio decidendi (issue estoppel). Where the Supreme Court has pronounced definitively that an intended appeal has no prospects of success, a party cannot circumvent that determination by instituting fresh proceedings in the High Court on the same issues.
The court expressed strong disapproval of the plaintiff's highly litigious conduct, noting that he had been involved in a plethora of court matters despite extant court orders against him and despite the property having been transferred to the third respondent in 2016 to his knowledge. The court endorsed the Supreme Court's emphasis on the need for finality in litigation and the impropriety of dragging respondents to court on unsustainable claims. The court noted that an analysis of whether the claim disclosed a cause of action would be superfluous once res judicata had been established.
This case reinforces the strict application of the doctrine of res judicata in Zimbabwean law and the principle of finality in litigation. It demonstrates that parties cannot circumvent unfavourable judgments by simply instituting fresh proceedings on the same issues between the same parties. The case also illustrates that res judicata applies not only to the ratio decidendi of a judgment but also to issues decided as part of that ratio. The award of costs on the higher attorney and client scale serves as a deterrent against vexatious and abusive litigation, particularly where a litigant persists in bringing claims that have already been definitively determined by the courts, including the apex court.
