The European Commission (Commission) has fined E.ON Energie AG (E.ON) for breaching a seal securing a room containing documents relevant to an inspection concerning suspected anti-competitive practices in the German electricity market. During a surprise inspection on 29 May 2006, the Commission sealed a room of documents for the night using a plastic film seal that displays a void sign if it has been tampered with. The seal displayed the void sign the following morning. As the documents contained in the sealed room had not yet been listed, the Commission was unable to ascertain whether documents had been removed by E.ON. Independent experts refuted E.ON’s claim that the seals may be faulty. The level of the fine is intended to demonstrate the seriousness of the Commission’s concern over the infringement.
