Winding up by Tribunal: Part I of the Companies Act governs Tribunal-initiated company liquidations under the amended provision. Section 270 provides that the provisions of Part I apply to the winding up of a company by the Tribunal, making the Part I winding-up framework operative for Tribunal-initiated liquidations. The section was later substituted by legislative reforms, replacing an earlier text that identified modes of winding up and applied the Act's winding-up provisions to each mode.
