retired subsequent to that date. In case of pensioners who retired prior to the specifed date, their pension would be computed afresh and would be payable in future commencing from the specifed date. No arrears would be payable. And that would take care of the grievance of retrospectivity. In our opinion, it would make a marginal diference in the case of past pensioners because the emoluments are not revised. The last revision of emoluments was as per the recommendation of the Third Pay commission (Raghubar Dayal Commission). If the emoluments remain the same, the computation of average emoluments under amended Rule 34 may raise the average emoluments, the period for averaging being reduced from last 36 months to last 10 months. The slab will provide slightly higher pension and if someone reaches the maximum the old lower ceiling will not deny him what is otherwise justly due on computation. The words "who were in service on 31st March, 1979 and retiring from service on or after the date" excluding the date for commencement of revision are words of limitation introducing the mischief and are vulnerable as denying equality and introducing an arbitrary fortuitous circumstance can be severed without impairing the formula. Therefore, there is absolutely no difculty in removing the arbitrary and discriminatory portion of the scheme and it can be easily severed.
