Section 4 (1) of the Act provides: "The Provincial Government or the District Magistrate, if satisfied with respect to any particular person that with a view to preventing him from acting in any manner prejudi cial to the public safety or the maintenance of public order it is necessary so to do, may, by order in writing, give anyone or more of the following directions, namely that such person . . . . . . . . . (c) shall remove himself from, and shall not return to, any area that may be specified in the order." , 530 Sub section (3) of the section lays down that "An order under sub section (1) made by the District Magistrate shall not, unless the Provincial Government by special order otherwise directs, remain in force for more than three months from the making thereof." The contention of the petitioner is that the restrictive provisions mentioned above, under which a person could be removed from a particular area or prohibited from returning to it are inconsistent with the fundamental right guaranteed by article 19 (1) (d) of the Constitution under which all citizens shall have the right "to move freely throughout the territory of India.
