The learned Judges of the Himachal Pradesh High Court who heard these two Writ Petitions and other Writ Petitions jointly found that Dr. Jiwan Lal, Dr. S.P. Kapoor and Dr. (Mrs.) Damyanti Kapur were appointed as Deputy Directors of Health Services on ad hoc basis in July 1975 and January 1976 respectively after the Rules came into force on 19.1.1974, that it has not been contended by them that they had been appointed in accordance with the Rules or after relation of the Rules, that Dr. Jiwan Lal, Dr. (Mrs.) Damyanti Kapur and Dr. S.P. Kapoor were specifically appointed 1053 on ad hoc basis and that, therefore, Dr. Jiwan Lal and Dr. (Mrs.) Damyanti Kapur cannot claim right to the post of Deputy Directors of Health Services or to seniority on the basis of their ad hoc appointments, though they can add the period of such appointment in the matter of experience for promotion and confirmation in view of the addition of notice to Rule 9 of the Rules.
