Civil Service Personnel Rule 45

45. A service personnel shall normally be promoted rank by rank without jumping step. However, in case of the service personnel organizations need to appoint external persons to a post to which they are not authorized to directly appoint a person according to the work nature or the specified qualification for the post, they initially appoint him to the post to which they are authorized to appoint directly and he may be promoted to the suitable post within one year if his performance is satisfactory. If the post is of the gazetted officer, the approval shall be obtained from the Union Civil Service Board after consultation under rule 14 (b).
