Article 15 1

1.   The redressive measures referred to in Article 14 shall remain in force only as long as, and to the extent that, it is necessary in view of the persistence of the practice distorting competition and the ensuing injury. To that end, the review procedure set out in paragraphs 2, 3 and 4 of this Article shall apply. The Commission shall regularly provide a written report to the European Parliament and to the Council on the effectiveness and impact of redressive measures.
