"7. No doubt, the above said Rule 5 stipulates other qualification such as Vaigai Dam (Bhavanisagar) Training as mandatory. However, unless the appellants depute the respondents for such training at the appropriate time, they could not be expected to complete the same. The respondents, who are the employees, may not compel the appellants to depute them for the training. The alleged non completion of the training by the writ petitioners/respondents herein within the stipulated period of not their fault and the same cannot be put against them, dis-entitling them for getting their promotion. It is also pointed out that the juniors to the respondents have marched ahead of them by getting a promotion. Therefore, the contention of the learned State Government Counsel that a person can be promoted based on merit and ability apart from seniority and the departmental promotion committee alone is competent to recommend the person fit for promotion cannot be accepted."
