and power to do it in any way that a natural person could do it. However, references to corporate capacity and powers have not quite been consigned to the dustbin of legal history. In many jurisdictions, directors can still be liable to their shareholders if they cause the company to engage in businesses outside its objects, even if the transactions are still valid as between the company and the third party. And many jurisdictions also still permit transactions to be challenged for lack of "corporate benefit", where the relevant transaction has no prospect of being for the commercial benefit of the company or its shareholders. As artificial persons, companies can only act through human agents. The main agent who deals with the company's management and business is the board of directors, but in many jurisdictions other officers can be appointed too. The board of directors is normally elected by the members, and the other officers are normally appointed by the board. These agents enter into contracts on behalf of the company with third parties. Although the company's agents owe duties to the company (and, indirectly, to the shareholders) to exercise those powers for a proper purpose, generally speaking third parties' rights are not impugned if it transpires that the officers were acting improperly. Third parties are entitled to rely on the ostensible authority of agents held out by the company to act on its behalf. A line of common law cases reaching back to Royal British Bank v Turquand established in common law that third parties were entitled to assume that the internal management of the company was being conducted properly, and the rule has now been codified into statute in most countries. Accordingly, companies will normally be liable for all the act and omissions of their officers and agents. This will include almost all torts, but the law relating to crimes committed by companies is complex, and varies significantly between countries.
