(63)Member States should ensure that when an undertaking is required by Union law to have elements of its sustainability reporting verified by an accredited independent third party, the report of the accredited independent third party should be made available either as an annex to the management report or by any other publicly accessible means. Such making available of that report should not pre-empt the outcome of the assurance opinion of which the third-party verification should remain independent. It should not entail any duplication of work between the auditor or the independent assurance services provider that expresses the assurance opinion and the accredited independent third party.
