The foregoing discussion yields the following results: (1) " Public order " is synonymous with public safety and tranquillity : it is the absence of disorder involving breaches of local significance in contradistinction to national upheavals, such as revolution, civil strife, war, affecting the security of the State; (2) there must be proximate and reasonable nexus between the speech and the public order; (3) section 3, as it now stands, does not establish in most of the cases comprehended by it any such nexus; (4) there is a conflict of decision on the question of severability in the context of an offending provision the language whereof is wide enough to cover restrictions both within and without the limits of constitutionally permissible legislation; one view is that it cannot be split up if there is possibility of its being applied for purposes not sanctioned by the Constitution and the other view is that such a provision is valid if it is severable in its application to an object which is clearly demarcated from other object or objects falling outside the limits of constitutionally permissible legislation; and (5) the provisions of the section are so inextricably mixed up that it is not possible to apply the doctrine of severability so as to enable us to affirm the validity of a part of it and reject the rest.
