139It also follows from that case-law, moreover, that the application of general presumptions is essentially dictated by the requirement to ensure the correct functioning of the procedures in question and to ensure that their objectives are not compromised. Thus, the recognition of a general presumption may be based on the incompatibility of access to the documents in certain procedures with the proper conduct of those procedures and on the risk that the procedures may be undermined, it being understood that the general presumptions enable the integrity of the conduct of the procedure to be preserved by restricting interference by third parties (see, to that effect, judgment of 25 September 2014, Spirlea v Commission, T‑306/12, EU:T:2014:816, paragraphs 57 and 58, and Opinion of Advocate General Wathelet in Joined Cases LPN and Finland v Commission, C‑514/11 P and C‑605/11 P, EU:C:2013:528, points 66, 68, 74 and 76).
