Section 731(b) in Police Regulations, Bengal , 1943
(b)Private arrivals. - (i) It is not possible to lay down hard and fast instructions but it should be remembered that the Hon'ble Ministers are entitled to receive the courtesy due to them even when their arrivals and departures are private. Ordinarily on such occasions the Deputy Inspector-General at Range headquarters and the Superintendent at district headquarters should make a point of meeting the Hon'ble Minister. The guiding consideration should be whether the officer's absence would be remarked upon as indicating lack of respect or attention to the Hon'ble Minister.
