Requests from the group supervisor to other supervisory authorities
Article 251
The group supervisor may invite the supervisory authorities of the Member State in which a parent undertaking has its head office, and which do not themselves exercise the group supervision pursuant to Article 247, to request from the parent undertaking any information which would be relevant for the exercise of its coordination rights and duties as laid down in Article 248, and to transmit that information to the group supervisor. The group supervisor shall, when it needs information referred to in Article 254(2) which has already been given to another supervisory authority, contact that authority whenever possible in order to prevent duplication of reporting to the various authorities involved in supervision.
