Explain the Doctrine of Ultra Vires.

The word 'ultra' means beyond and the word 'vires' means powers. In the case of a company whatever is not stated in the memorandum as the objects or powers is prohibited by the doctrine of ultra vires. As a result, an act which is ultra vires is void, and does not bind the company. Neither the company nor the contracting party can sue on it. Also, as stated earlier, the company cannot make it valid, even if every member assents to it. The general rule is that an act which is ultra vires the company is incapable of ratification. An act which is intra vires the company but outside the authority of the directors may be ratified by the company in proper form [Rajendra Nath Dutta v. Shilendra Nath Mukherjee, (1982). The doctrine of ultra vires was first enunciated by the House of Lords in a classic case, Ashbury Railway Carriage and Iron Co. Ltd. v. Riche, (1878) L.R. 7 H.L. 653. The memorandum of the company in the said case defined its objects thus: "The objects for which the company is established are to make and sell, or lend or hire, railway plants to carry on the business of mechanical engineers and general contractors." The rule is meant to protect shareholders and the creditors of the company. If the act is ultra vires (beyond the powers of) the directors only, the shareholders can ratify it. If it is ultra vires the articles of association, the company can alter its articles in the proper way and thereby such acts can be duly ratified.
