Which resolution type is needed for the winding up of a company requiring over 75% approval?

The correct answer is the special resolution. In the context of winding up a company, a special resolution is typically required for decisions that significantly affect the company's structure or operations, including its dissolution. This type of resolution necessitates a higher threshold of approval — generally, at least 75% of the votes cast must be in favor for the resolution to pass.

Special resolutions are essential in corporate governance because they afford a level of protection for shareholders, ensuring that significant decisions are made with a strong consensus. The requirement for a higher majority helps to reinforce the legitimacy and community support of such pivotal actions as winding up a company, which can have major implications for all stakeholders involved.

Ordinary resolutions, on the other hand, only require a simple majority (over 50%) of votes, making them unsuitable for actions requiring greater consensus, such as winding up. Majority resolutions do not exist as a distinct category and typically refer to any decision passed by a simple majority. Class resolutions pertain to decisions made by a particular class of shareholders and are not relevant when discussing the overarching requirement for winding up a company. Thus, in matters of winding up that demand over 75% approval, a special resolution is the necessary type to consider.
