Briefly explain the doctrine of 'ultra vires' under the Companies Act.
Ultra means 'beyond' or 'in excess of’ and vires means 'powers'. Thus, ultra vires means an act or transaction beyond or in excess of the powers of the company. An act or transaction shall be ultra vires if - - act or transaction is not permitted or authorised by the Companies Act, 2013; - it falls outside the object clause of memorandum; and - its achievement is not incidental to the attainment of main objects. Effects of ultra vires transactions:- (i) An act which is ultra vires the company is void(invalid) and has no legal effect. (ii) the company can not fulfill the ultra vires contract. (iii) Even approval of an ultra vires contract by the whole body of shareholders does not make an ultra vires contract valid .
