the eligibility criteria for pay up-gradation of Government Primary School, Middle School and High School Teachers in the senior and selection grade was laid down with effect from 01.06.2012. As per Clause 1(b) of the Notification, for the purpose of counting of eight (8) years service in the entry grade, services rendered in Adhoc/Deficit service continued by regularization into Government Service without any break shall be counted as qualifying service. The Notification dated 19.07.2013 was followed by a Corrigendum dated 02.07.2014 (Annexure - 14) by which, besides the services rendered in Adhoc and Deficit, the service rendered under the CSS continued by regularization came to be incorporated. Therefore, it is the case of the petitioners that they are eligible to count the services rendered by them under the SSA (CSS) for their pay up-gradation. The service particulars of the petitioners have been indicated in the form of a chart in paragraph No. 7 of the writ petition.
