Regulation (EEC) No 1247/92 shall not provide any entitlement for periods prior to 1 June 1992.

The periods of residence and periods of employment or of selfemployment completed on the territory of a Member State before 1 June 1992 shall be taken into consideration for the determination of rights acquired under the provisions of Regulation (EEC) No 1247/92.

Subject to paragraph 1, a right shall be acquired pursuant toRegulation (EEC) No 1247/92 even where it relates to a contingency that occurred before 1 June 1992.

All special non-contributory benefits which have not been awarded or which have been suspended by reason of the nationality of the person concerned shall, on the application of the person concerned, be awarded or resumed with effect from 1 June 1992, provided that the rights previously determined have not given rise to a lump-sum payment.

The rights of persons to whom a pension was awarded prior to 1 June 1992, may, on the application of the persons concerned, be reviewed, taking account of the provisions of Regulation (EEC) No 1247/92.

If an application referred to in paragraph 4 or 5 is submitted within two years from 1 June 1992, the rights acquired pursuant to Regulation(EEC) No 1247/92 shall have effect from that date, and the provisions of the legislation of any Member State concerning the forfeiture or limitation of rights may not be invoked against the persons concerned.

If an application referred to in paragraph 4 or 5 is submitted after the expiry of the two-year period after 1 June 1992, rights which have not been forfeited or which are not time-barred shall have effect from the date onwhich the application was submitted, except where more favourable provisions of the legislation of any Member State apply.

The application of Article 1 of Regulation (EEC) No 1247/92 may not result in the withdrawal of benefits which are awarded before 1 June 1992 by the competent institutions of the Member State under Title III of Regulation(EEC) No 1408/71 to which Article 10 of the latter Regulationis applicable.

The application of Article 1 of Regulation (EEC) No 1247/92 may not result in the rejection of an application for a special noncontributory benefit awarded as a supplement to a pension, which was submitted by the person concerned who had satisfied the conditions for the award of this benefit before 1 June 1992, even where the person concerned resides on the territory of a Member State other than the competent Member State, provided that the application for the benefit is submitted within a period of five years starting from 1 June 1992.

Not with standing the provisions of paragraph 1, any special noncontributory benefit, granted as a supplement to a pension, which has not been awarded or which has been suspended by reason of the residence of the person concerned on the territory of a Member State other than the competent Member State shall, on the application of the person concerned, be awarded or resumed with effect from 1 June 1992, in the first case from the date on which the benefit should have been awarded, and in the second case on the date of suspension of the benefit.

Where special non-contributory benefits as referred to in Article 4 (2a) of Regulation(EEC) No 1408/71 may, during the same period and for the same person, be granted pursuant to Article 10a of that Regulation by the competent institution of the Member State in the territory of which that person is resident and pursuant to paragraphs 1 to 10 of this Article by the competent institution of another Member State, the person concerned may only aggregate those benefits up to the limit of the highest amount of the special benefit he could claim under one of the legislations in question.

The detailed rules of application of paragraph 11, and in particular the application, with regard to the benefits referred to in that paragraph, of the clauses for reduction, suspension or abolition provided for under the legislation of one or more Member States and the allocation of the differential additional amounts shall be set by decision of the Administrative Commission on Social Security for Migrant Workers and, where appropriate, by common accord of the Member States concerned or their competent authorities.
