Section 10 of Act V of 1861 absolutely forbids any police officer from taking up any employment whatever other than his duties under that Act, save with the express and written permission of the Inspector General. Such permission has been given generally so as not to debar police officers from engaging in casual literary work, to the extent allowed under the Government Servants Conduct Rules, from serving as examiners, or from engaging in an honorary capacity in the work of charitable, religious, or social organizations. The Inspector-General has the right, however, to withdraw his permission in any case in which , in his opinion, the interests of Government are prejudiced. The restrictions imposed by Section 10 of the Police Act are binding on police officers throughout their service, whether on leave or duty.
