The applicant claimed to have purchased immovable property (Lot Number 17 Weirmouth Smallholdings) from joint sellers on 10 July 2014 for USD$70,000, having paid over 50% of the purchase price. The property was subsequently sold to the first respondent (Zimbabwe Housing Company), who obtained title. The applicant instituted multiple lawsuits attempting to assert his interests over the property: HC 1377/19 (default judgment for ejectment against applicant), HC 2042/19 (applicant's rescission application struck off as fatally defective), HMT 72-20 (applicant's suit dismissed on grounds of res judicata), and SC 93/21 (Supreme Court dismissed applicant's application for condonation). The applicant then brought the present application seeking registration of a caveat over the property to secure his interests pending another action (HC 5713/21) to obtain title. The first respondent raised a plea of res judicata as an objection in limine.
The first respondent's point in limine was upheld and the application was dismissed with costs.
The binding legal principles established are: (1) The doctrine of res judicata applies where there has been a final and definitive judgment by a competent court, and the three essential elements are satisfied: same parties (or their privies), same subject matter, and same cause of action. (2) These requirements must be interpreted expansively in appropriate cases, particularly where prior judgments sound both in personam and in rem, to permit issue estoppel even where strictly different relief is sought, provided the same underlying question arises in both cases. (3) The requirement of 'same parties' does not require an exact line-up of litigants; the addition of disinterested officials or nominal parties does not defeat the plea. (4) Where the relief sought (such as a caveat) is anchored on an underlying right that has already been definitively determined by a court, res judicata will apply notwithstanding that different relief is now sought. (5) A judgment founded purely on adjectival/procedural law without determining the merits does not constitute a final and definitive judgment for res judicata purposes, but where courts have made substantive findings on parties' rights, those constitute final determinations that estop further litigation.
The court noted the Supreme Court's previous observations about the applicant's litigious nature and the multiple court proceedings he had instituted (HC 1236/17, HC 8602/17, HC 1377/19, HC 2042/19, MUTP 3015-16/18, Mutare Magistrates Court 2102/17, and files before the anti-corruption court, Law Society of Zimbabwe and Judicial Service Commission). The court stated it would 'steer clear from temptation to further chastise applicant, in word or costs, for his recalcitrance' as the Supreme Court had already said and done enough on the matter. The court emphasized the public policy rationale that 'to allow litigants to plough over the same ground hoping for a different result will have the effect of introducing uncertainty into court decisions and will bring the administration of justice into disrepute.' These observations underscore judicial concern about vexatious litigation and abuse of court process.
This case demonstrates the robust application of the res judicata doctrine in Zimbabwean law to prevent vexatious litigation and ensure finality of judgments. It clarifies that: (1) the requirement of 'same parties' should be interpreted expansively, particularly where judgments sound in rem; (2) seeking different relief (e.g., a caveat versus ownership) does not necessarily constitute a different cause of action if the underlying right has been conclusively determined; (3) the addition of purely formal parties (like the Registrar of Deeds) does not defeat res judicata; and (4) courts will distinguish between procedural dismissals that do not address merits and substantive determinations that conclusively resolve parties' rights. The case reinforces the principle that litigants cannot circumvent final judgments by repackaging claims in different forms or adding nominal parties. It serves as a warning against persistent, unmeritorious litigation after rights have been definitively adjudicated.
