The Use of Force as a Plea of Necessity

Article 2(4) of the UN Charter contains a general prohibition of the use of force. Articles 42 and 51 authorize departures from this prohibition in two circumstances: Security Council authorization and self-defense. These two circumstances are conceptualized as justifications. They provide for legally-warranted departures from the general rule. As a result, a justified use of force is not wrongful. Justifications are different from excuses where the action remains wrongful, but the wrongdoer may be released from responsibility for the wrongdoing.
