Which type of resolution requires a 75% majority for effectiveness in company meetings?

A special resolution is the correct choice as it requires a 75% majority for effectiveness in company meetings. This type of resolution is typically needed for significant decisions that affect the structure or operation of a company, such as amending the articles of association, changing the company name, or decisions concerning the winding up of the company.

The threshold of a 75% majority underscores the importance of these decisions, ensuring that a substantial proportion of stakeholders agree before a resolution can pass. This is a safeguard that adds a layer of consensus among shareholders, reflecting the gravity of the matters being voted on.

In contrast, an ordinary resolution typically requires only a simple majority — more than 50% of the votes cast. Written resolutions do not specifically refer to a majority percentage but rather allow shareholders to make decisions without a formal meeting by signing a document, which can speed up the decision-making process. Unanimous resolutions, as the name suggests, require 100% agreement, making them even more stringent than special resolutions and less common in practice.
