Update 9 February 2021 see also Gilles Cuniberti’s review here.
I earlier reviewed Szpunar AG’s Opinion in C‑641/18 Rina, on which the Court held on 7 May, confirming the AG’s view. Yannick Morath has extensive analysis here and I am happy to refer. Yannick expresses concern about the extent of legal discretion which agencies in various instances might possess and the impact this would have on the issue being civil and commercial or not. This is an issue of general interest to privatisation and I suspect the CJEU might have to leave it to national courts to ascertain when the room for manoeuvre for such agencies becomes soo wide, that one has to argue that the binding impact of their decisions emanates from the agencies’ decisions, rather than the foundation of the binding effect of their decisions in public law.
I was struck by the reference the CJEU made at 50 ff to the exception for the exercise of official authority, within the meaning of Article 51 TFEU.
