In the case of a society formed for no purpose of gain, the liability of members of the committee for a debt incurred on behalf of the society, resolves itself into a question of agency, or authority given by each of them. All members authorising any officer of the society to overdraw upon the account of the society at its bankers are liable for future further overdrafts until they revoke such authority. Members also who have notice of the existence of an overdraft, whether by the appearance, in the society’s accounts, of a charge of interest by its banker, or otherwise, and who do not protest or actually dissent, are also liable.
