Disn1issing the appeal to this Court, HELD : (1) Unless a person has a right to a post, an order of reversion from that post cannot amount to dismi~al or removll within the meaning of Art. 331 and, a person gets a right to a post only when he is substantively appointed to it. Therefore, if the appointments of the appellants were officiating appojntments of either type mentioned in F. R. 9(19), the revision to State Civil Service \VOuld not attract Art. 311.

(2) Since the appointees to the Cadre posts in the Indian Administrative Service \Vere appointe<l under r. 9 of the Indian Administrative Service (Cadre) Rules, the appointments could not have been made in any capacity other than in an officiating capacity. [587 H-588 A] (3) As regards the other appellants also though the order of appointment does not indicate that the appointments were in officiating capacity, the fact that they retained their lien in their posts in the State Civil Services shows that that 1hey were not appointed substantively to the senior duty posts but only in an officiating capacity.
