“10. It is apparent that there is a policy of the Railways to grant regularization to these fresh face substitutes. We need not refer to all the circulars issued in this behalf, but a perusal of the documents especially those filed as additional documents clearly show that the Railways has a policy of regularizing these fresh face substitutes. This, in our opinion, is a clear indicator that while making appointment of fresh face substitutes, the field of choice should be wide and all citizens who are qualified and eligible should be given a chance to take part in the selection process. Though these appointments may be termed as short term appointments, the facts placed on record reveal that thousands of fresh face substitutes have been regularized and have become employees of the Railways because of the policy of the Railways. It is, therefore, imperative that while appointing fresh face substitutes, a transparent system of appointment is followed. It would be much better if the Railways follows the regular system of appointment rather than making appointments on ad hoc basis of fresh face substitutes. However, as and when exigencies of service require that fresh face substitutes have to be appointed, then also the field of choice cannot be limited only to those who have undergone their apprenticeship training with the Railways since that would patently violate Article 14 and 16 of the Constitution of India depriving those who have not undergone apprenticeship training with the Railways of an equal opportunity for applying for these posts.
