I have no idea. Who owns it? Who decides what is published?
Are the writers appointed or just hires off the street?
Unlike a newspaper the council is largely made up of appointees of the Pope. I think that would justify saying what they write reflects his views, hence, “the Vatican”.
But like any other committee, they don't always reflect the views of the person who appointed them.
But whether they do or don't, this document has no binding teaching authority on anyone, and Cdl. Turkson made that quite clear by using words like "contribution" and "suggestion". It's a position paper wherein the council expresses an opinion on things. If it were the Pope's opinion and he wanted people to think of it that way, it would have been issued over his signature.
The skeptical can further tell that I'm right in saying that it has no binding authority by looking at Fr. Z's blistering rejection of it. Fr. Z's orthodoxy is hard to impeach.
