Prior to this, respondent No. 2 S. L. Gupta was also appointed as a Temporary Engineer on an ad hoc basis w.e.f. May 19, 1969 by calling his name through the Employment Exchange i.e. subsequent to the coming into force of the Class II Rules. Their appointments were dehors the rules to meet the exigencies of service.
