The general meeting of a company is generally convened by a resolution of the board of directors. A meeting is also convened when:
Required to do so by members holding minimum one tenth of the paid voting up share capital of the company
A notice of resignation is placed along with a statement stating the circumstances that must be brought to the notice of the company and a signed requisition.
A meeting has to be convened within 21 days of the requisition and 28 days of giving the notice. Therefore, unless a meeting can be held at a short notice, the directors will be required to convene a meeting at the latest within 11 days after the receipt of the requisition. If the Articles are quiet, then 2 or more members, who are holding not less than one tenth of the issued share capital, may convene a meeting. If adequate number of directors is not available to hold a board meeting, then a single member can also convene it. The courts in UK have an extraordinary power to convene board meetings when it becomes impossible to hold one by the board of directors.
