Summarize the following court judgment. tition No. 215 of 1989. (Under Article 32 of the Constitution of India.) M.S. Gujral	 Ms. Kirti Misra and B .B. Sawhney for the Petitioners. G.B. Pari	 O.C. Mathur	 Ms. Meera and section Sukumaran for the Respondents. The Judgment of the Court was delivered by K. RAMASWAMY	 J. This writ petition under article 32 filed on behalf of about 450 erstwhile employees of M/s. Burmah Shell retired between May 1	 1979 and December 1984	 is for a mandamus or direction to the respondents to restore full pension (which had been commuted) to the petitioner Nos. 2 to 5 and others similarly situated upon the expiry of 12 1/2 years from date of retirement in case of those retired prior to April 1985 and after 11 1/3 years to those retired prior to April 1	 1985 from their respective dates of retirement. They claim that though in their previous Writ Petition No. 590/87 disposed of by a Division Bench of this Court on May 11	 1988 of which one of us (Ranganath Misra	 J.) was a member	 a hike in the pension effective from May 1	 1988 was granted. Consideration of the present relief had been left over for a later period. Admittedly	 the petitioners in Writ Petition No. 590/87 sought two reliefs	 namely	 (i) restora tion of the commuted portion of the pension	 and (ii) en hancement of pension or par with the pensioners of the Hindustan Petroleum Corporation Limited	 for short 'HPCL '. During the course of hearing	 claim for the 964 first relief was given up and submission was confined to the second relief. This Court accepted the contentions of the petitioners and ordered a seizeable hike in the pension. The relief in this writ petition squarely covers relief No. 1 of Writ Petition No. 590/87. But the ground on which the peti tioners have again come before the Court within a short spell is that their hope of the respondent 's sister concern	 namely	 HPCL	 restoring commuted portion of pension to its pensioners has been smashed as it has deferred its decision on the issue till 1992. Their learned counsel contends that in Common Cause & Ors. vs Union of India	 ; this Court upheld the 15 years formula and directed that the commuted portion of the pension should be restored to all the civil servants as well as the armed forces personnel of the Central Government effective from April 1	 1985. It is maintained that as principle the same would be applicable to the petitioners as well. The respondents	 it is claimed	 have to bear an additional liability of only a sum of Rs.1	02	41	635 out of its huge profits without in any manner affecting its functioning. When the employees of the Central Govt. and other Public Sector Undertakings are receiving the same benefits	 the denial thereof to the petitioners is arbitrary	 unjust and unfair and offends article 14 of the Constitution. There is no scheme in vouge in other Public Sector Undertakings like commuted pension scheme except in HPCI. Though HPCL has postponed action in this regard till 1992	 the petitioners are not precluded to approach this Court for redressal and the previous decision does not operate as res judicata. This Court having accorded in equity benefits of pension	 which is a legal right of the petitioner	 the relief also may be granted to the petition ers. Shri Pai	 learned counsel for the respondents	 has resisted all these contentions. The short question is wheth er it is a fit case for interference and issue of a direc tion to the respondents to give the relief as prayed for. Admittedly	 the petitioners claimed this relief in Writ Petition No. 590/87. This Court after appropriate considera tion held that a sizeable hike in pension would meet the ends of justice. Admittedly	 Burmah Shell has a unique scheme known as "Burmah Shell India Pension Fund" with its own rules. This Court held that the retired personnel would be entitled to a hike in pension at par with pensioners of HPCL. Admittedly	 HPCL has not accorded to its pensioners the relief of restoration of the commuted portion of pension after the expiry of 15 years. The order passed by this Court is as recent as May 11	 1988. After such a short time lag and in the absence of any substantial change in the posi tion	 in our considered view	 it is not desirable to enter tain the claim for restoration of commuted pen 965 sion. Admittedly	 the petitioners are governed by a special scheme	 which is not at par with Government employees or the other Public Sector Undertakings. In all fairness Shri Pai also has stated that as and when HPCL revises its scheme the petitioners would be entitled to the same benefits. Grant or ' the relief at this stage would create disparity between the personnel who receive pension from HPCL and the re spondents. We find sufficient justification in the conten tion of Shri Pai. So we do not feel justified that it would be appropriate to interfere and grant the relief as prayed for. The writ petition is accordingly dismissed	 but without costs. G.N. Petition dismissed.

Some of the erstwhile employees of Burmah Shell	 in an earlier writ petition	 claimed restoration of the commuted portion of pension and enhancement of pension on par with the pensioners of Hindustan Petroleum Corporation Limited	 (HPCL). At the time of hearing	 the claim for restoration of the commuted portion of pension was given up. This Court accepted the claim of the petitioners as regards enhancement of pension and ordered a sizeable hike in the pension. The present writ petition claims the same relief which was given up at the time of hearing of the earlier writ petition	 viz.	 restoration of commuted portion of pension. Admitted ly	 HPCL had deferred its decision till 1992 in this regard. On behalf of the petitioners it was contended that though	 HPCL has deferred its decision till 1992	 the peti tioners were not precluded from approaching this Court and that the earlier decision did not operate as res judicata. On behalf of the respondents it was contended that as soon as HPCL revises its scheme the petitioners would also be entitled to the benefit thereof and that grant of the relief earlier would create disparity between the persons who receive pension from HPCL and those from the Respondent. Dismissing the writ petition	 this Court	 HELD: 1.1. It would be inappropriate to interfere and grant the relief as prayed for at this stage since that would create disparity between the personnel who receive pension from Hindustan Petroleum Corporation Ltd. and the respondent Corporation. [965B] 963 1.2. This Court has already held that the retired per sonnel of Burmah Shell would be entitled to a hike in pen sion at par with pensioners of HPCL. (W.P. No. 590/87 decid ed on 11.5. 1988). HPCL has not accorded to its pensioners the relief of restoration of the commuted portion of pension after the expiry of 15 years. The order passed by this Court is as recent as May 11	 1988. After such a short time lag and in the absence of any substantial change in the posi tion	 it is not desirable to entertain the claim for resto ration of commuted pension. The petitioners are governed by a special scheme	 which is not at par with Government em ployees or the other Public Sector Undertakings.
