688Where an exculpatory document has not been communicated, it is settled case-law that the undertaking concerned must establish that its non-disclosure was able to influence, to its detriment, the course of the procedure and the content of the Commission’s decision. It is thus sufficient for the undertaking to show that it would have been able to use the exculpatory documents for its defence, in the sense that, if it had been able to rely on them during the administrative procedure, it would have been able to invoke evidence which was not consistent with the inferences made at that stage by the Commission and therefore could have had an influence, in any way at all, on the assessments made by the Commission in any decision, at least as regards the gravity and duration of the conduct in which the undertaking was found to have engaged and, accordingly, the level of the fine. In that context, the possibility that a document that had not been disclosed might have had an influence on the conduct of the procedure and the content of the Commission’s decision can be established only after a provisional examination of certain evidence showing that the undisclosed documents might have had – from the aspect of that evidence – a significance which ought not to have been overlooked (see Aalborg Portland and Others v Commission, paragraph 371 above, paragraphs 74 to 76 and the case-law cited).
