A challenge to a sale in execution, whether pending or completed, does not constitute a defence against a claim for eviction by the registered owner of property. Once a sale in execution has been confirmed by the Sheriff/Messenger of Court and transfer has been effected to the purchaser against payment of the purchase price, the registered owner is entitled to evict the former owner on the basis of ownership rights alone under the rei vindicatio principle. The registered owner need only prove ownership and that the defendant is in possession without consent - no further allegations are required. This is a real right enforceable against the world at large, and the court has no discretion to refuse eviction on grounds of equity, convenience, or pending challenges to the sale process, unless the sale is void ab initio (as opposed to merely voidable for irregularity). Any challenge to the regularity of a sale conducted under Magistrates' Court rules must be brought in the Magistrates' Court under the applicable rules, and the High Court will not inquire into such matters in eviction proceedings except on appeal from the Magistrates' Court decision.
