Compliance with Rule 5(2) of the Companies (Winding Up) Rules, which requires service of the petition and notice of set down upon the respondent company before the hearing of an application for provisional winding up, is mandatory. Rule 247(3) of the High Court Rules does not dispense with this requirement - it only governs the form, content, publication and service of the provisional order once made, and enshrines the company's right to be heard on the return day for confirmation. A respondent company must not be deprived of the opportunity to oppose the grant of a provisional winding up order before it is made, given the serious consequences that flow from such an order including diminution in personal status and removal of control over assets. A provisional winding up order obtained without compliance with mandatory service requirements is improperly obtained and must be set aside.
