European Union – Pension. A national rule, such as that at issue in the main proceedings, pursuant to which the 20% supplement to a total permanent incapacity pension was suspended during the period in which the beneficiary of that pension received a retirement pension in another member state or in Switzerland, constituted a provision on reduction of benefit for the purposes of art 12(2) of Regulation (EC) No 1408/71. The Court of Justice so ruled in proceedings concerning the decision of the applicant National Institute for Social Security, Spain, to suspend the payment of the supplement to the respondent's total permanent incapacity pension because he had been in receipt of a Swiss retirement pension.
