(78)Ensuring that resolution authorities have the same resolution tools and powers at their disposal will facilitate coordinated action in the event of a failure of a cross-border group. Further action, however, is necessary to promote cooperation and prevent fragmented national responses. To agree to a group resolution scheme when resolving group entities, resolution authorities should therefore be required to consult each other and cooperate in resolution colleges. To provide for a forum for discussion and reaching such agreement, resolution colleges should be established around the core of the existing colleges of supervisors through the inclusion of resolution authorities and the involvement of competent ministries, EIOPA and, where appropriate, authorities responsible for the insurance guarantee schemes. Resolution colleges should not be decision-making bodies, but platforms facilitating decision-making by national authorities, while it should be for the national authorities concerned to take the joint decisions.
