An application for the Commission to prescribe the measures necessary for the enforcement of a final decision of that Commission, accompanied, where appropriate, by a periodic penalty payment, may not be made, unless the authority concerned expressly refuses to enforce the decision, before the expiry of a period of three months from the date of notification of that decision.
Where the Commission has, in the decision whose enforcement is being pursued, set a time limit within which the authority concerned must take the enforcement measures it has prescribed, the request may not be submitted until that time limit has expired.
