The said application was considered by the Managing Committee and it was resolved that the aforesaid Smt.

It has further been recorded in the said resolution that the petitioner be allowed to continue her service against lien for another year with effect from September 26, 1996 and that petitioner be reappointed against lien for another year. The Secretary was directed to make proper arrangement for submitting necessary papers for taking prior permission from the DIS (SE), Nadia, for allowing the petitioner to continue her service against the vacancy lien (second year w.e.f. September 26, 1996). Upon such application having been made by the School authorities DIS (SE), however, accorded approval to the petitioner continuing for a period of 6 months in the said leave (lien) vacancy w.e.f. October 1, 1996. The petitioner was accordingly informed of the same by the Managing Committee that she has been appointed Assistant Teacher with effect from October 1, 1996 for 6 (six) months vide leave lien of Smt. Bandana Das (annexure 'P12') dated November 26, 1996.
