27Consequently, in order to justify a refusal to grant access to a document whose disclosure has been requested, it is not sufficient, in principle, for the requested document to be covered by an activity mentioned in Article 4(2) of Regulation No 1049/2001. As a rule, the institution to which the request is addressed must also provide explanations as to how access to that document could specifically and actually undermine the interest protected by the exception or exceptions relied on (judgments of 1 July 2008, Sweden and Turco v Council, C‑39/05 P and C‑52/05 P, EU:C:2008:374, paragraph 49, and of 27 February 2014, Commission v EnBW, C‑365/12 P, EU:C:2014:112, paragraph 64). Moreover, the likelihood of that interest being compromised must be reasonably foreseeable and not purely hypothetical (judgment of 1 July 2008, Sweden and Turco v Council, C‑39/05 P and C‑52/05 P, EU:C:2008:374, paragraph 43).
