1. Where the application of this Regulation, or the delegated or implementing acts adopted pursuant thereto, requires major changes to be made to a Member State’s national statistical system, the Commission may grant, by means of implementing acts, duly justified derogations to the Member State, for a maximum duration of 1 year for data with a quarterly periodicity, of 2 years for data with an annual periodicity, and of 4 years for data with a multiannual periodicity. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 13(2). The relevant Member State shall submit a duly justified request to the Commission within 3 months of the date of entry into force of this Regulation or the delegated or implementing acts adopted pursuant thereto. When granting the derogations, the Commission shall take into account the comparability of Member States’ statistics and the timely calculation of the required representative and reliable European aggregates. The Commission shall also ensure that the requirements related to statistics, metadata and quality covered under this Regulation that were previously covered under the repealed regulations continue to be met without interruption.
2. Where a derogation remains justified at the end of the period for which it was granted, the Commission may adopt an implementing act granting a further derogation for a maximum period of 1 year. The relevant Member State shall submit a request setting out the reasons and detailed grounds in support of such an extension to the Commission not later than 6 months before the end of the period of validity of the derogation granted pursuant to paragraph 1.
