The respondent was employed by the appellant as a sales and marketing manager in 2008. On 1 June 2010, he was moved to operations as a manager, which he regarded as a demotion. He reported the matter to a labour officer and after failed conciliation, the matter was referred to arbitration. On 11 October 2011, the arbitrator ordered the appellant to suspend the demotion and negotiate a new contract, and separately ordered that the respondent be paid a bonus equivalent to 30% of his salary. The appellant appealed against the bonus award. Whilst that appeal was pending, the respondent approached an arbitrator for quantification of damages. The court a quo quantified damages on 4 July 2014, including amounts related to bonus. The appeal against the merits of the bonus award was subsequently successful, with the appeal court determining that the appellant was not liable to pay the respondent a bonus. Despite this, the court a quo proceeded to quantify the unpaid bonus and related damages, ordering payment of $31,134.86 as bonus shortfall and $23,022.16 as damages.
The appeal was allowed with costs. Paragraphs 3 and 4(b) of the judgment a quo were set aside.
A judgment on liability will always take precedence over and, where necessary, trump a judgment quantifying damages, not because of any ranking of courts but because liability naturally and logically precedes quantification to complete the cause of action under the law of damages. Damages are not payable in a vacuum - they rest on an obligation which gives content to the liability. In the absence of an established obligation, there can be no competent order for the payment of damages even if quantification was done prior to a determination of liability. Where liability and quantification are determined at different times, the judgment on liability will precede and be binding on the court seized with quantification. Once a court has finally determined an issue, the court becomes functus officio and loses authority and competence to adjudicate on the matter again. Judgments belong to courts as institutions, not to individual judges, and are binding on the entire court regardless of how it is constituted. A court hearing an appeal on quantum does not have jurisdiction to determine the merits of liability when that issue is properly before another court.
Makarau JA made observations about the challenges that emerge from parties pursuing the same issue before different judges who may each be seized with different aspects of their appeals, resulting in divergent judgments from the same court. The Court also noted in passing that sentiments denoting personal claims to judgments by individual judges are misplaced, as judgments belong to the institution and not to the individuals who constitute the court. The judgment also commented on the misapplication of the principle of stare decisis, noting that the situation before the court a quo was not an instance where the doctrine applied, as it was not a case of one court of parallel jurisdiction being called upon to adopt or apply a principle discovered by an earlier court, but rather the same court making pronouncements at different times on two components of the same cause of action.
This case is significant in Zimbabwean jurisprudence (and potentially instructive for South African law given similar legal principles) as it clarifies the relationship between judgments on liability and quantification of damages. It establishes that where liability and quantification are determined at different times by different constitutions of the same court, the judgment on liability takes precedence and is binding on the court seized with quantification. The case also reinforces the principle that judgments belong to the court as an institution, not to individual judges, and that once a court has determined an issue, it becomes functus officio on that matter. The judgment emphasizes the logical sequence that must be followed in the law of damages: liability must first be established before quantification can competently proceed. It also clarifies the limits of a court's jurisdiction when hearing an appeal on quantum - such a court cannot simultaneously determine the merits of liability when that issue is properly before another court.
