53.2. Despite any provision to the contrary, a retired public service employee may, without having to undergo the qualification process, be re-appointed under this Act to a position in the same class as the class he belonged to before retiring or to any other position with less stringent conditions of eligibility for which a deputy minister or a chief executive officer has recognized him as having the necessary skills. Such a re-appointment is only possible to meet a temporary need and where the person’s particular expertise and experience are required. The Conseil du trésor prescribes the terms and conditions of such a re-appointment, which may only be for a fixed term.
