  To the extent that a duty of obedience is included in the concept of political authority, there can be different forms of obedience on the part of subjects. This implies a very distinct dimension of political authority. When a political authority issues a command and the subject has a duty to obey, what is the nature of this duty? One might have a duty to obey a command merely because it commands the subject to do something that is just and any alternative action would be unjust. Here the duty to obey would depend on the content of the command. Commands that are unjust or perhaps even commands that require actions that are not exclusively just may not involve duties at all.
