Articles 6, 50, 51(3) and 52 to 59 shall apply mutatis mutandis to persons covered by a special scheme for civil servants.

However, if the legislation of a competent Member State makes the acquisition, liquidation, retention or recovery of the right to benefits under a special scheme for civil servants subject to the condition that all periods of insurance be completed under one or more special schemes for civil servants in that Member State, or be regarded by the legislation of that Member State as equivalent to such periods, the competent institution of that State shall take into account only the periods which can be recognised under the legislation it applies.

If, account having been taken of the periods thus completed, the person concerned does not satisfy the conditions for the receipt of these benefits, these periods shall be taken into account for the award of benefits under the general scheme or, failing that, the scheme applicable to manual or clerical workers, as the case may be.

Where, under the legislation of a Member State, benefits under a special scheme for civil servants are calculated on the basis of the last salary or salaries received during a reference period, the competent institution of that State shall take into account, for the purposes of the calculation, only those salaries, duly revalued, which were received during the period or periods for which the person concerned was subject to that legislation.
