An application or summons issued against an entity that is not a legal or natural person (lacking legal personality) is null and void ab initio. A housing scheme, being merely a scheme run by a union rather than a separate juristic person, cannot sue or be sued in its own right. There can be no cause of action in an application involving effectively only one party due to improper citation. An employee or official of an entity cannot be joined as a party to proceedings absent privity of contract or other legal basis establishing a cause of action against them personally. An application for review must comply with the requirements of sections 26-27 of the High Court Act and Order 33 of the High Court Rules, including the requirement under Rule 257 to state shortly and clearly the grounds upon which review is sought.
