(1)In reckoning the service of a constable for the purposes of this Act, approved service in any other police force, or if he has served in more than one, then in each police force in which he served for not less than three years approved service, and from which with the written sanction of the chief officer of that force he removed to another force, or to the Royal Irish Constabulary, shall be reckoned as service in the Royal Irish Constabulary; and the length of service which a constable is entitled to reckon in the police force from which he removes shall be stated in the said written sanction, or shall otherwise be sent in writing by the chief officer of that force to the Inspector General of the Royal Irish Constabulary on the removal of the constable into the Royal Irish Constabulary. For the purposes of this Act, approved service shall mean such continuous service as may, after deduction, if any, for sickness, misconduct, or other cause, be established to the satisfaction of the police authority having the control of such police force, to have been diligent and faithful service.
(2)Where a constable with the knowledge of the Inspector General belongs to the army reserve, his absence when called out for training or for permanent service shall not prevent his service in the Constabulary being deemed to be continuous service for the purposes of this Act, and he shall be entitled on returning to the Constabulary after the end of such absence, to reckon any service which he was entitled to reckon at the commencement thereof.
