10. The first respondent is now working in a Government School having been selected and appointed on 16.12.2012 and joined duty on 17.12.2012. For a brief period of 2 years 3 months and 3 days from 14.09.2010 to 16.12.2012, the first respondent was working in the second respondent – School, which is an Aided Minority Educational Institution. On account of the minority status, the educational agency, which is established and adminstering the second respondent – School is not required to obtain prior approval of the Government to fill up vacancy caused on account of resignation, retirement or death of the existing incumbent. Therefore, the Corporate Management, namely, Bishop of Tuticorin / Management of R.C.Schools, Tuticorin Diocese, had issued appointment order, dated 13.09.2010 and the first respondent was posted in the second respondent – School. The first respondent did not agitate his rights before submitting his resignation and getting relieved from the second respondent – School. Much after his retirement, the first respondent sought to wake up a closed issue by submitting his representation for the first time on 12.06.2015. In Paragraph No.4 of the affidavit filed in support of the writ petition, the first respondent would state that the representation dated 12.06.2015 was a reminder. However, the copies of the alleged earlier representations, dates of the alleged earlier representations have not been mentioned. Therefore, we can safely conclude that for the first time, the first respondent sent a representation on 12.06.2015 requesting the second appellant to reckon his services rendered by him in the second respondent – School for the period from 14.09.2010 to 16.12.2012 and disburse salary. This was rightly rejected by the second appellant by proceedings, dated 27.07.2015, on the ground that the first respondent's appointment was not approved by the Department. It is thereafter the first respondent filed the writ petition challenging the order dated 27.07.2015 as also the proceedings, dated 21.05.2012, by which the proposals sent by the Management for approval of appointment of the first respondent was returned. Thus, the facts will clearly demonstrate that the attempt of the first respondent is belated and cannot be entertained and it is barred by laches and no explanation has been set forth.
