A resolution of the members (or of a class of members) of a private company must be passed—
as a written resolution in accordance with Chapter 2, or
at a meeting of the members (to which the provisions of Chapter 3 apply).
A resolution of the members (or of a class of members) of a public company must be passed at a meeting of the members (to which the provisions of Chapter 3 and, where relevant, Chapter 4 apply).
Where a provision of the Companies Acts—
requires a resolution of a company, or of the members (or a class of members) of a company, and
does not specify what kind of resolution is required,
what is required is an ordinary resolution unless the company's articles require a higher majority (or unanimity).
Nothing in this Part affects any enactment or rule of law as to—
things done otherwise than by passing a resolution,
circumstances in which a resolution is or is not treated as having been passed, or
cases in which a person is precluded from alleging that a resolution has not been duly passed.
