The petitioner seeks quashing of the Circular dated 29.10.1991 (Annexure P-10) whereby the respondents have taken into account only the regular service while reckoning 8/16 years of service for the purposes of granting the proficiency step up. The petitioner also seeks a mandamus to direct the respondents to count the work-charge service for the afore-said service benefits. In view of the decision of the Hon'ble Supreme Court in The Punjab State Tubewell Corporation Workers Union versus The State of Punjab and others, 2008 (5) SLR 684 as well as a recent decision of the Hon'ble Supreme Court in Punjab State Electricity Board and others versus Jagjiwan Ram and others (2009) 3 SCC 661, no case to issue the desired direction is made out.
