Where a billeting requisition has been produced to the chief officer of police for the area specified in the requisition he shall, on the demand of the officer commanding any portion of the regular air force, or on the demand of an officer or airman authorised in writing by such an officer commanding, billet on the occupiers of premises falling within the last foregoing section, being premises at such place in that area as may be specified by the officer or airman by whom the demand is made, such number of persons or vehicles as may be required by that officer or airman, not exceeding the number specified in the requisition.

Without prejudice to the provisions of the next following section, a chief officer of police shall exercise his functions under this section in such manner as in his opinion will cause least hardship to persons on whom billeting may take place.

A chief officer of police may to such extent and subject to such restrictions as he thinks proper authorise any constable, or constables of any class, to exercise his said functions on his behalf, and the foregoing provisions of this section shall apply accordingly.
