In summary judgment proceedings, particularly in eviction matters, a defendant must demonstrate a bona fide defence by alleging specific facts with sufficient clarity and completeness that, if established, would enable them to succeed. Vague generalities and conclusory allegations not substantiated by solid facts are insufficient to defeat summary judgment. A person who has lost ownership of property through a judicial sale cannot resist eviction merely on the basis of pending appeals, review applications, or criminal investigations, unless and until ownership is restored by court order. An innocent purchaser who acquires property at a duly advertised public auction conducted by the sheriff, pays the purchase price, and obtains transfer is entitled to the protection of the law and can enforce their rights of ownership, including eviction of former owners.
