Regarding Seniority of Direct Recruits

Respected Sir, a state govt undertaking had advertised for the post of group A officer who has worked in a supervisor or managerial capacity for the period of 5 years. I was working with a nationalised bank and got selected to state govt undertaking after fulfilling eligible criteria and cracking written and interview. I secured 3rd rank out of 15. There was a clause in appointment letter to join within 30 days otherwise seniority will be as per joining date. Since, I was working as Deputy Manager in nationalised bank I requested state government undertaking to allow extension in joining time got approval of the same. Accordingly I joined after gettiing relieved from bank after 45 days from the date of appointment order. Now the state govt undertaking has placed me on 15th no in seniority as I could not join within 30 days. Now I request you to provide me with the courts judgement where a meritorious candidate joins late due to the reliveing issue from the previous employer and seniority of the person remains in a sequence of a merit
