Article 2
Initiation of an infringement procedure 1. No more than one infringement procedure shall be initiated against the same undertaking based on the same facts. For this purpose, no decision on whether or not to initiate an infringement procedure shall be taken by the Executive Board of the ECB or by the competent national central bank until they have informed and consulted with one another. 2. Prior to a decision to initiate an infringement procedure, the ECB and/or the competent national central bank may request from the undertaking concerned any information relating to the alleged infringement. 3. Either the Executive Board of the ECB or the competent national central bank, as the case may be, shall, upon request, be entitled to assist and cooperate with the other in carrying out the infringement procedure, in particular by transmitting any information that may be deemed relevant. 4. Unless otherwise agreed between the parties concerned, any communication between the ECB or the competent national central bank, as the case may be, and the undertaking concerned shall be conducted in the official Community language (or in one of the official Community languages) of the Member State in whose jurisdiction the alleged infringement has occurred.
