+1 to Mathias's point here. EU access-to-document type cases don't necessarily impact the ownership of IP / question of whether something is PD.
While I've not fully analysed the copyright question for this particular scenario - or even had time to fully digest the new CJEU ruling (and what follows cannot be considered WMF's position on anything), I see that the deletion discussion was already closed as a Speedy Keep. So since things are moving pretty quickly, I'll just note for now that the European Commission seems to take the position that the mere inclusion of international standards (drafted by third parties, not by or for the European Commission) into EU law does not result in that standard being released to the PD. This is discussed here [1].
I have found an example: inclusion of IFRS accounting standards into EU law; see Recital 14 here [2] ("
The copyright, the database rights, and any other intellectual property
rights in the IFRS and related interpretations issued by the
International Financial Reporting Interpretations Committee are owned by
the IFRS Foundation. A copyright notice should therefore be included in
the Annex to this Regulation."). The copyright notice that it refers to appears in the Annex to that law[3], and is worded: "
Reproduction allowed within the European Economic Area. All existing rights reserved outside the EEA, with the exception of the right to reproduce for the purposes of personal use or other fair dealing. Further information can be obtained from the IASB at www.iasb.org"
