The benchmark for the GPI, insofar as it is relevant at all in the CCWG, is that it is in the GPI for ICANN to perform its mission, and _/only/_ its mission, properly. It is also in the GPI for ICANN to be accountable to its stakeholders. Can we agree on that? IMHO, that’s really all we need to say about the GPI.
I would agree. I'd also go further and suggest that this is in the public interest and the qualifier 'global' is entirely otiose. I cannot think that any public authority that is a member of the Governmental Advisory Committee could disagree with the proposition that "(a) it is in the /public interest/ for ICANN to perform its mission, and only its mission, properly. (b) It is also in the /public interest/ for ICANN to be accountable to its stakeholders." (Otherwise, it would not be part of the GAC, surely)
