no material to demonstrate that on 09.08.2019, when the DLC had held its meeting, vacancy for the year 2014-15 was available. Thirdly, it is not in dispute that the order dated 19.09.2016, dismissing the writ petition, i.e. W.P.(C) 4980/2016, filed by the petitioner for seeking compassionate appointment has attained finality as such the present writ petition is held to be barred by principles of res judicata as well as issue estoppel. Fourthly, it is not in dispute that as per ratio laid down in the case of Achyut Ranjan Das (supra), as on 09.08.2019, when DLC had held its meeting more than two years from the date of application had lapsed.

However, later on, the Three Judge Bench of the Supreme Court of India, in the case of N.C. Santhosh v. State of Karnataka & Ors., AIR 2020 SC 1401: (2020) 7 SCC 617: 2020 0 Supreme (SC) 237, after considering the case of Canara Bank (supra) and several other cases, held as follows:
