Joel Simon Silonda v Vusumuzi Nkomo

On 26 January 2010, the plaintiff (Joel Simon Silonda), aged 94 at trial, sold 10 acres of land (part of 100 acres of Lot 5A, Umguza District) to the defendant (Vusumuzi Nkomo) for US$10,000 initial payment with further instalments due. At the time of signing, there was no subdivision permit as required by section 40 of the Regional, Town and Country Planning Act [Chapter 29:12], rendering the agreement null and void from inception. The defendant paid a total of US$19,550 toward the agreement and, believing the sale was valid, made substantial improvements to the property including constructing two houses, installing electricity, flushing a borehole, and other developments valued at approximately US$90,000-US$97,833. The parties later fell into dispute, with the plaintiff seeking eviction, rentals, and holding over damages, while the defendant counterclaimed for compensation for improvements made in good faith.

• Whether the agreement of sale was null and void for non-compliance with sections 39(1)(b)(i) and 40 of the Regional, Town and Country Planning Act
• Whether the plaintiff was entitled to reasonable rentals arising from the defendant's occupation of the property
• Whether the defendant had been unjustly impoverished and the plaintiff unjustly enriched as a result of improvements made by the defendant on the property
• Whether the defendant, as a bona fide possessor, had a lien entitling him to compensation before eviction
• The quantum of compensation due to the defendant for improvements

1. The purported Deed of Sale dated 26 January 2010 in respect of a portion of Umguza 100 Acre, Lot 5A is confirmed to be null and void for want of compliance with the mandatory provisions of the Regional, Town and Country Planning Act [Chapter 29:12]. 2. The plaintiff's claim for payment of reasonable rentals and holding over damages is dismissed with costs. 3. The plaintiff is ordered to pay the defendant the sum of US$125,000 being compensation for improvements effected by the defendant on the plaintiff's property. 4. Prescribed interest is to be levied on the amount from 24 June 2015 to date of full payment. 5. The plaintiff is to pay costs of suit.

1. An agreement for the sale of land that has not been subdivided in accordance with a permit granted under section 40 of the Regional, Town and Country Planning Act [Chapter 29:12] is null and void ab initio and unenforceable, as it violates the prohibition in section 39(1)(b)(i) of the Act. 2. A void sale agreement cannot be converted into or read as a lease agreement to justify claims for rentals where the parties clearly intended and executed a sale, not a lease. 3. Where a defendant has been unjustly impoverished by making improvements on another's property pursuant to a void contract, and the plaintiff has been unjustly enriched thereby, the general enrichment action is available if all prerequisites are met: (a) the defendant must be enriched; (b) the enrichment must be at the expense of another with causal connection between enrichment and impoverishment; (c) the enrichment must be unjustified; (d) the enrichment must not fall within classical enrichment actions; and (e) there must be no positive rule of law refusing the action. 4. A bona fide possessor who has effected useful improvements on land in good faith believing they had purchased it has a real lien over the property, entitling them not to be evicted without compensation for the value added by the improvements. 5. The usefulness of improvements must be measured in terms of added value to the property, not on the basis of whether the owner requires the structures for personal use.

The court made several important obiter observations: 1. Courts should not label witnesses as liars during cross-examination as the ultimate determination of credibility is the prerogative of the trier of fact after considering all evidence. 2. Defects in pleadings may be cured by overwhelming evidence supporting the claim, particularly where the substance of the claim is clearly understood by all parties. 3. Courts have an obligation to "do justice between man and man" and their decisions must not encourage parasitic tendencies where one party seeks to benefit unfairly from another's expenditure. 4. The principle that courts will not enforce illegal contracts may be relaxed where public policy demands it, particularly in cases involving collateral or connected transactions that do not amount to indirect attempts to enforce the illegal contract (referencing Jajbay and Cassim 1939 AD 537). 5. The court emphasized that a legal practitioner properly trained in law is assumed to know how to frame questions for cross-examination, and a lay litigant has no control over that process and cannot be held responsible for counsel's cross-examination strategy. 6. The court expressed concern about preventing parties from being rendered destitute and homeless through strict application of legal formalities where they have acted in good faith.

This case is significant in Zimbabwean (and by extension South African) jurisprudence for its comprehensive application of unjust enrichment principles in the context of invalid land sale agreements. It reinforces the strict enforcement of statutory subdivision permit requirements under land planning legislation, confirming that agreements made in violation of section 39(1)(b)(i) and section 40 of the Regional, Town and Country Planning Act are void ab initio and unenforceable. The judgment importantly illustrates how courts will invoke equitable principles to prevent unjust enrichment even where the underlying contract is illegal or void, particularly where one party has acted in good faith. The case establishes that a bona fide possessor who makes improvements in good faith has a real lien over the property, entitling them to compensation before eviction. It also demonstrates that usefulness of improvements is measured by added value to the property, not the owner's subjective need for the structures. The judgment serves as a warning against parties entering land sale agreements without proper subdivision permits and highlights the court's willingness to protect innocent parties from being rendered destitute through application of strict legal formalities.
