 It is easy to see why this constitutes an attractive way of justifying civil disobedience, since it justifies it by appeal to the same values that ground the pro tanto duty to obey the law. On the other hand, as Simmons notes, if there is no general duty to obey the law, there would seem to be no presumption in favor of obedience and thus no special need for a justification of civil disobedience; obedience and disobedience would stand equally in need of justification (Simmons 2007: ch 4).
