that the upgradation scheme was introduced and the benefit was given to police personnel only prospectively and his claim on the basis of G.O.Ms.No.844, Home (Pol.V) Department dated 3.6.97 and another G.O.Ms.No.937, Home (Pol.III) Department dated 21.7.98 cannot be accepted retrospectively. Having given upgradation to similarly placed Grade I Police Constables, Head Constables and Special Sub Inspectors of Police retrospectively pursuant to the orders passed by this Court, there is nothing wrong in giving the same benefit to the petitioner. Therefore, the negation of the petitioner's prayer on the ground that the upgradation scheme was introduced and the benefit was given only prospectively and it cannot be given retrospectively, is untenable and unjustified, he pleaded.
