Engineer long back, though the exact date of promotion has not been disclosed. The petitioner was recruited directly in the respondent Board from the open market as Trainee Engineer. At the time of his first promotion to the post of Assistant Engineer, he could have sought relaxation in experience in view of his past experience as Trainee Officer in the Corporation, but since he has already been promoted, therefore, now at this stage, he cannot claim for counting of the said period, particularly when he has been further promoted to the post of Executive Engineer. Actually, the petitioner wanted to count the said service period in the Corporation towards his seniority in the respondent Board. Admittedly, this benefit cannot be granted to the petitioner, as he was directly appointed as Trainee Engineer from open market. The service rendered on a post in a different organisation cannot be counted for the purpose of seniority on the subsequent post where the appointment was made by direct recruitment under a different employer. Thus, the claim of the petitioner has been rightly rejected by the respondent Board.
