Pension entitlement for Appellate Board members balanced with option to forego pension and subscribe to contributory provident fund. The rules substitute the leave regime, permitting earned leave, half pay leave with commutation for medical reasons, extraordinary unpaid leave within term limits, and encashment of earned leave at term end subject to an overall cap. They introduce a pension entitlement for members except where removed, set pension accrual on a periodic basis with an aggregate cap aligned to High Court Judges, and create a time limited election to forego pension to subscribe to a Contributory Provident Fund; those entering office after the specified date may only opt for the Provident Fund.
