(47)Requisite majorities should be established by national law to ensure that a minority of affected parties in each class cannot obstruct the adoption of a restructuring plan which does not unfairly reduce their rights and interests. Without a majority rule binding dissenting secured creditors, early restructuring would not be possible in many cases, for example where a financial restructuring is needed but the business is otherwise viable. To ensure that parties have a say on the adoption of restructuring plans proportionate to the stakes they have in the business, the required majority should be based on the amount of the creditors' claims or equity holders' interests in any given class. Member States should, in addition, be able to require a majority in the number of affected parties in each class. Member States should be able to lay down rules in relation to affected parties with a right to vote which do not exercise that right in a correct manner or are not represented, such as rules allowing those affected parties to be taken into account for a participation threshold or for the calculation of a majority. Member States should also be able to provide for a participation threshold for the vote.
