To succeed in a winding up application under s 206(g) of the Companies Act on 'just and equitable' grounds based on the quasi-partnership/deadlock principle, an applicant must establish: (1) proper standing as a 'contributory' under s 207(1), meaning shares held in their own name for at least six months of the preceding eighteen months; (2) existence of a quasi-partnership arrangement, being some express, tacit or implied arrangement creating partner-like obligations beyond ordinary corporate relationships, typically involving mutual confidence, participation in management, and restrictions on transfer of interests; (3) wrongful conduct or breach of such arrangement by other members destroying the special relationship; and (4) absence of adequate alternative remedies. A minority shareholder controlling their spouse's shares does not satisfy the contributory requirements. Mere breakdown of trust or personal relationships between shareholders in a small company, without proof of breach of special arrangements, is insufficient to justify winding up on just and equitable grounds.
