The Commission shall decide that a Member State shall repeal an extension of the rules decided on by that Member State pursuant to Article 125f(1):
where it finds that the extension in question to other producers excludes competition in a substantial part of the internal market or jeopardises free trade, or that the objectives of Article 33 of the Treaty are endangered;
where it finds that Article 81(1) of the Treaty applies to the rules extended to other producers. The Commission’s decision with regard to those rules shall apply only from the date of such a finding;
where it finds after checks that this subsection has not been complied with.]
