Artikel 13

1. Except for benefits in respect of invalidity, old age, survivors or occupational disease which are paid by the institutions of two or more Contracting Parties in accordance with the provisions of Article 29 or of Article 47, sub-paragraph (b), this Convention shall not confer or maintain entitlement to several benefits of the same nature or to several benefits to one and the same period of compulsory insurance.
2. Provisions in the legislation of a Contracting Party for the reduction, suspension or suppression of benefits where there is overlapping with other benefits or other income, or because of an occupational activity, shall apply also to a beneficiary in respect of benefits acquired under the legislation of another Contracting Party or in respect of income obtained, or occupation followed, in the territory of another Contracting Party. This rule shall not, however, apply to benefits of the same nature payable in respect of invalidity, old age, survivors or occupational disease by the institutions of two or more Contracting Parties in accordance with the provisions of Article 29 or of Article 47, sub-paragraph (b).
