The third respondent in the writ petition, Kerala State Electricity Board, is the appellant. The first respondent/writ petitioner was an employee of the KSEB. He is entitled to get gratuity at the rate payable under the Kerala Service Rules. At the time of his retirement, claiming that he is entitled to get the Gratuity at the rate provided under the Payment of Gratuity Act, he moved the statutory authority. The said authority by Ext.P1 order directed to pay Gratuity amount of Rs.3,50,000/- with 10% interest from 01.07.03 to the writ petitioner. The KSEB, after depositing the principal amount, filed an appeal before the appellate authority. The appellate authority dismissed the appeal by Ext.P2 order.
