52. The scope of Section 144 CrPC enumerates the principles and declares the situations where exercise of rights recognised by law, by one or few, may conflict with other rights of the public or tend to endanger public peace, tranquillity and/or harmony. The orders passed under Section 144 CrPC are attempted to serve larger public interest and purpose. As already noticed, under the provisions of CrPC complete procedural mechanism is provided for examining the need and merits of an order passed under Section 144 CrPC. If one reads the provisions of Section 144 CrPC along with other constitutional provisions and the judicial pronouncements of this Court, it can undisputedly be stated that Section 144 CrPC is a power to be exercised by the specified authority to prevent disturbance of public order, tranquillity and harmony by taking immediate steps and when desirable, to take such preventive measures. Further, when there exists freedom of rights which are subject to reasonable restrictions, there are contemporaneous duties cast upon the citizens too. The duty to maintain law and order lies on the authority concerned and, thus, there is nothing unreasonable in making it the initial judge of the emergency. All this is coupled with a fundamental duty upon the citizens to obey such lawful orders as well as to extend their full cooperation in maintaining public order and tranquillity.
