114It follows from that case-law that the Commission may assume that the infringement – or the participation of an undertaking in the infringement – has not been interrupted, even if it has no evidence of the infringement in relation to certain specific periods, provided that the various actions which form part of the infringement pursue a single purpose and are capable of falling within the framework of a single and continuous infringement; and where the undertaking concerned has not relied on indicia or evidence establishing that, on the contrary, the infringement, or its participation in it, has not been pursued during those periods.
