(7)Given the exceptional character of the possibility for the resolution authority to exclude a liability or class of liabilities from bail-in under Article 44(3) of Directive 2014/59/EU, the resolution authority's assessment must be well founded. Where such exclusions would imply the use of the resolution fund, the resolution authority should provide a solid explanation on the exceptional circumstances leading to the exclusion. This explanation is essential for the Commission to be able to fulfil its mandate under Article 44(12) of Directive 2014/59/EU, pursuant to which the Commission must decide, within 24 hours of the notification by the resolution authority of the decision to exclude certain liabilities, whether it should prohibit or request amendment to the proposed exclusion. The explanation provided to the Commission by the resolution authority should be proportionate, and the need for expedience as warranted by the circumstances specific to the case should be taken into account.
