Where an institution is failing or likely to fail, national resolution authorities should have at their disposal a minimum harmonised set of resolution tools and powers. Their exercise should be subject to common conditions, objectives, and general principles. Once the resolution authority has taken the decision to put the institution under resolution, normal insolvency proceedings should be excluded except if they need to be combined with the use of the resolution tools and at the initiative of the resolution authority. Member States should be able to confer on the resolution authorities powers and tools in addition to those conferred on them under this Directive. The use of those additional tools and powers, however, should be consistent with the resolution principles and objectives as laid down in this Directive. In particular, the use of such tools or powers should not impinge on the effective resolution of cross-border groups.
