Consequently, their pay was fixed in the revised scale of Rs. 500. 00 being the minimum in the revised scale. It was, however, ordered that they would be entitled to next increment not on their normal date of increment in the lower scale but after completion of twelve months of service in the revised scale, that is, with effect from 1/01/1981.

The service rendered in the lower scale cannot be counted for earning increment in the higher scale.
