The Selection Grade and Special Grade is given to the employee on completion of 10 years and 20 years of service respectively. The case of the petitioner is that the he has not been granted selection grade and special grade from due date and the benefit of Government instructions issued by G.O.Ms.No.1381 dated 5.10.90 has not extended to him. 5. As the representation filed by the petitioner was not answered, the petitioner has approached this Court with a prayer for issuance of a Writ in the nature of Mandamus to grant selection grade and special grade to the petitioner from the due date with consequential benefit of refixing of seniority as per revised pay scale. 6.

Therefore, request of the petitioner for grant of grade of Head Master cannot be allowed to him. 8. There is force in this contention of the learned Government Advocate. 7.
