In course of time a vacancy arose in the post of the Upper Division Clerk in the Department of Museums •,md Zoos. One M. S. Pillai was the scniormost Lower Division Clerk in that Department but when the post of promotion was offered to him he declined it on the ground <>f ill-health. The appellant was next in order of seniority amongst the Lower Division Clerks in the Department of Museums n:.icl Zoos and since her rank and lien in that Department were maintained, she was offered the post of the Upper Division Clerk. She conveyed her inability to accept that post for the time being and thereupon the !st respondent, who was next in order of seniority, was appointed provisionally as an Upper Div;s;nn Clerk. His appointment was made w;thout prejudice to the claims of the senior~ in the Department of Museums and Zoos. On the retirement of M. S. Pillai, a permanent \•aeancy in the post of the Upper Division Clerk arose in the Department of Museums a:.id Zoos. On July 6, 1970 the appellant, who was working in the Department of Agriculture, conveyed her willingness to accept that post. By an order dated March 18, l 971 she was appointed as an Upper Division Clerk -and later on May 3, 1971 she was further promoted as a Senior Superinte.idertt. Both of these appointments as also the order by which his representation was rejected by the Government, were challenged in the Writ Petition by the 1st respondent.
