Australian Securities Commission v Marlborough Gold Mines Ltd

The Australian Securities Commission (ASC) appealed to the High Court of Australia against a decision concerning Marlborough Gold Mines Ltd. The dispute centred on the ability of a company to alter its memorandum of association.

The High Court was required to determine whether a company's memorandum of association, which defines its status and the liability of its members, could be altered by the company. This involved considering the effect of sections 115 and 117 of the Corporations Law and the fundamental principles of company law regarding the constitution of a company.

The Court's reasoning was grounded in the principle that a company's memorandum of association, upon incorporation, serves as its fundamental and unalterable law, unless the governing statute expressly permits such alteration. This principle, as articulated in cases like *Ashbury Railway Carriage and Iron Co v Riche*, establishes that companies are incorporated for specific objects and purposes as expressed in their memorandum, and their powers are limited accordingly. The Court noted that this principle applies to companies incorporated under the Corporations Law, akin to statutory corporations whose powers are defined by their founding legislation.
