are bound by the Notification No. CSR/27/13 which provides for final time limit of 10(ten) years from the year of Registration of the candidates to clear all three Parts of the Examination. The fact that the petitioners were registered in 2010 would make no difference to the petitioners being bound by the said Notification. The facts in Pijush Kanti Mallick(supra) were entirely different. In that case, the petitioner had taken admission in B.Com.(Hons) in 2011-12 academic session and had cleared both Parts I and II Examinations in 2016 and was, however, disallowed from writing the Part-III Examination by the guidelines framed by the University Grants Commission on 15th October, 2015. In this case, the Notification of the Calcutta University cannot be by-passed at the instance of any student of the University. Further, since this court has passed orders rejecting similar prayers of petitioners in other matters, hence there is no compelling reason for this court to take a different view in the present case. The petitioners in an earlier matter unsuccessfully challenged the order passed in the writ before the appeal court.
