Social Security Court dismisses appeal; pension base calculated by retroactive valuation, not filing date comparison.

The Supreme Social Security Court dismissed the appellant's cassation appeal regarding the calculation of his pension base. The appellant argued that the base should be calculated by comparing the pension base index to the base amount valid at the time of the pension application. The court held that the base must be determined by valuing the original pension base according to rules in force up to the application date. Consequently, the court found the lower court's interpretation of the relevant statute correct and rejected the claim.
