43Having regard to the nature of the interests protected in the context of a proceeding under Article 81 EC, the conclusion reached in the preceding paragraph of this judgment applies regardless of whether the application for access concerns a proceeding which has already been closed or a proceeding which is pending. The publication of sensitive information concerning the economic activities of the undertakings involved is likely to harm their commercial interests, regardless of whether a proceeding under Article 81 EC is pending. Furthermore, the prospect of such publication after that proceeding is closed runs the risk of adversely affecting the willingness of undertakings to cooperate when such a procedure is pending (see, by analogy, Commission v Éditions Odile Jacob, cited in paragraph 26 above, paragraph 124).
