Here the author discusses the grounds of civil disobedience in a constitutional democracy. He comments on the conditions under which we may, by civil disobedience, properly oppose legally established democratic authority. He argues that in a reasonably just democratic regime, civil disobedience, when it is justified, is normally to be understood as a political action which addresses the sense of justice of the majority in order to urge reconsideration of the measures protested and to warn that in the firm opinion of the dissenters the conditions of social cooperation are not being honored.
