Désobéissance civile et libéralisme

Can citizen disobey the law, coming from the will of the majority and the decision of the legitimately elected parliament, merely because it seems to them unjust ? Opposing the conservative thought, which defends the establish order et condemns any transgression, contemporary liberal thought provided a defense of the democratic legitimacy of civil disobedience. However, the rawlsian and habermasian justifications of civil disobedience seems very moderated when compared to the political thought of disobedient activists themselves, namely Gandhi, Martin Luther King Jr. and Howard Zinn. This unknown « disobedient thought » reveals the shortcomings and assumptions of the liberal concept of civil disobedience.
