Explanation:

The Supreme Court upheld the Centre’s one rank, one pension (OROP) scheme for the armed forces.

• The Bench held, “We find no constitutional infirmity in the OROP principle as defined in the government’s communication of November 7, 2015, on the implementation of the pension scheme.”
• The OROP scheme stipulated that benefits would be effective for pensioners from the cut-off date of July 1, 2014. Pensions of past pensioners would be refixed on the basis of pensions of retirees in the calendar year 2013.
• The Centre had promised that pensions of “all pensioners would be protected.” Finally, the scheme mandated the re-fixation of pension every five years.
• The judgment dealt with a petition filed by the Indian Ex-Servicemen Movement, complaining that pensioners of the same rank, who were a “homogeneous class”, were arbitrarily being given varying pensions under the OROP scheme.
• The amount of pension, they argued, should be uniform across armed forces personnel who retired with the same rank. They contended that the OROP had created a separate class among the personnel equally situated in rank and length of service. However, the court did not accept the argument.

Hence both statements are correct.
