The question of regularizing the service of the appellant in the facts of this case and in view of the law laid down in Secretary, State of Karnataka vs. Uma Devi (3) reported in (2006) 4 SCC 1, does not arise. However, the appellant cannot be denied salary for the period he has discharged duties as an Assistant Teacher and / or for the period during which the respondents have utilized his services. Having said so, regard is also had to the Divison Bench judgment of this Court in Harendra Ch. Nath vs. State of Tripura and Others, reported in 2013 (2) GLT 1094, whereby recovery of arrear salary was restricted to a period of 3 (three) years prior to the date of filing of the writ petition. In the instant case, the writ petition seeking arrear salary was instituted on 08.10.2013. Therefore, in view of Harendra Ch. Nath (supra), the appellant would be entitled to receive arrear salary only from the three year period prior to the date of institution of the WP(C) 6225/2013. In other words, the appellant cannot claim arrear salary beyond three years before the filing of the writ petition.
