Superior officer may perform duties imposed on subordinate officer

Every Police officer of rank superior to that of a Constable may perform any duty assigned by any law or by a lawful order to any officer subordinate to him and where any duty has been imposed on any subordinate, every superior officer, when it shall appear to him necessary, may aid such subordinate or supplement his duties or may issue any other order in supersession of his order or may prevent him in the performance of his duties whenever it shall appear to him necessary or expedient so to do for giving convenient effect to the law or for avoiding an infringement thereof.
