Title:
Civil_disobedience

Context:
Civil disobedience is usually defined as pertaining to a citizen's relation to the state and its laws, as distinguished from a constitutional impasse in which two public agencies, especially two equally sovereign branches of government, conflict. For instance, if the head of government of a country were to refuse to enforce a decision of that country's highest court, it would not be civil disobedience, since the head of government would be acting in her or his capacity as public official rather than private citizen.

Question:
What group of people cannot be part of civil disobedience?
