The Commission may, by decision, impose periodic penalty payments in order to compel an undertaking to stop an infringement of competition rules in accordance with an earlier decision. In such a case, a daily amount is fixed which has to be paid for every day the infringement continues after the date stipulated in that decision. The Commission enjoys the same power where an undertaking refuses to supply complete and correct information that has been requested by decision or to submit to an investigation which has been ordered by decision.
