4.Where uncertainty about the determination of the applicable legislation requires contacts between the institutions or authorities of two or more Member States, at the request of one or more of the institutions designated by the competent authorities of the Member States concerned or of the competent authorities themselves, the legislation applicable to the person concerned shall be determined by common agreement, having regard to Article 13 of the basic Regulation and the relevant provisions of Article 14 of the implementing Regulation.
Where there is a difference of views between the institutions or competent authorities concerned, those bodies shall seek agreement in accordance with the conditions set out above and Article 6 of the implementing Regulation shall apply.
5.The competent institution of the Member State whose legislation is determined to be applicable either provisionally or definitively shall without delay inform the person concerned.
6.If the person concerned fails to provide the information referred to in paragraph 1, this Article shall be applied at the initiative of the institution designated by the competent authority of the Member State of residence as soon as it is appraised of that person’s situation, possibly via another institution concerned.
