For an affidavit to be valid in motion proceedings in Zimbabwe, the commissioner's stamp must clearly identify both the person before whom the oath is taken and the office or capacity in which they act as commissioner of oaths. Mere reference to the enabling legislation (Justices of the Peace and Commissioners of Oaths Act) without specifying the commissioner's designation is insufficient. The failure to indicate the commissioner's specific capacity (e.g., legal practitioner, magistrate, police officer) renders the affidavit void ab initio and incurably defective. Without a valid founding affidavit, there is no valid application before the court. This defect cannot be cured by subsequent explanation or inference.
