1. Ex-Servicemen Contributory Health Scheme - Services of all the appointees like the petitioners, initially appointed for a period of 12 months, could be renewed, subject to good performance and existence of work warranting such extension - The record of the case shows that the petitioners' work and conduct has not been up to the mark - Posts in question are contractual in nature and as per the Scheme, are required to be filled up only on contractual basis - This part of the Scheme is not under challenge by the petitioners - That being so, posts, which are contractual in nature, would necessarily be filled up through employees, to be appointed on contract.
