11.1 Learned advocate further submits that realizing the wrong interpretation or wrong classification made, the KPCL negotiated with the remaining employees and settled the revision of pension in terms of the government order, however, effective from 04.05.2017. The modification of the KPCL order in conformity with the order of the government would be evidence that the understanding of the KPCL of the government order and the introduction of another class of employees was justifiably incorrect. It is submitted that the KPCL having accepted the revision of pension to other employees similarly placed and retired during the same period, on parity, the petitioners/respondent Nos. 3 to 9 are entitled to a revised pension in terms of the government order.
