Of the contracts entered into before adjudication some are still said to be void. A power of attorney is the best example of a void act of a lunatic.1 While in some of these cases it does not appear where the power was void originally, or whether it has been avoided, in others it clearly appears that the power is void. Thus a third person may raise the question of the validity of the power.2 Appointment of agents by means less formal than by power of attorney are generally held to be merely voidable.3
