has no connection with the existing scheme, different considerations enter the decision making process. One such consideration may be the financial implications of the scheme and the extent of capacity of the employer to bear the burden. Keeping in view its capacity to absorb the financial burden that the scheme would throw, the employer would have to decide upon the extent of applicability of the scheme. That is why in Nakara's case this Court drew a distinction between continuance of an existing scheme in its liberalised form and introduction of a wholly new scheme; in the case of the former all the pensioners had a right to pension on uniform basis and any division which classified them into two groups by introducing a cut-off date would ordinarily violate the principle of equality in treatment unless there is a strong rationale discernible for so doing and the same can be supported on the ground that it will subserve the object sought to be achieved. But in the case of a new scheme, in respect whereof the retired employees have no vested right, the employer can restrict the same to certain class of retirees, having regard to the fact-situation in which it came to be introduced, the extent of additional financial burden that it will throw, the capacity of the employer to bear the same, the feasibility of extending the scheme to all retirees regardless of the dates of their retirement, the availability of records of every retiree, etc. It must be realised that in the case of an employee governed by the CPF scheme his relations with the employer come to an end on his retirement and receipt of the CPF amount but in the case of an employee governed under the pension scheme his relations with the employer merely undergo a change but do not snap altogether. That is the reason why this Court in Nakara's case (AIR 1983 SC 130) drew a distinction between liberalisation of an existing benefit and introduction of a totally new scheme. In the case of pensioners it is necessary to revise the pension periodically as the continuous fall in the rupee value and the rise in prices of essential commodities necessitates an adjustment of the pension amount but that is not the case of employees governed under the CPF scheme, since they had received the lump sum
