Thanks, but to nitpick a bit, it seems to be a statement by the director of the Health Dept. of Hawaii. and does not seem to be an official policy statement by the State of Hawaii. Or it may be. I'm confused by it, especially where she states that he is a natural born citizen. What exactly determines that?
It's an official statement by the State of Hawaii, because the Director is an agent of that state, in the capacity the director fills and is the one in charge of the Department that directly handles the original records dealing with the birth certificate and also issues the "certified copy" of a birth certificate to whomever needs a legal copy.
You can't get too much more offiical than that, at least for a public statement. For a court, you can get more "official" -- simply by printing out the "certified copy" and whatever other records they may request.
But, again -- the department that would issue/print those very records, is that same department that made that official statement to the public.
Now, consider if the statement had been made in another department, one that did not directly handle the records, and a department that had nothing to do with issuing the "certified copy" when requested by a court -- would that other department be "more official" for the State of Hawaii than this one?
Well, I think you can tell, right away, that if this statement had been issued by another department, the first thing that would have been said is "How does that other department know this, when they don't even handle the records, they don't maintain the records, they are not responsible for the records and they do not even issue the certified copy of the records to a court for an official copy!" ... I think you can see what I mean, if some other department had done that ... :-)
As far as who makes that determination of who is a natural born citizen ... well when all is said and done -- it's going to be the Supreme Court who makes that final determination for this case -- if -- they ever get around to it -- which is doubtful.
BUT, if the Supreme Court hasn't gotten around to making that final determination -- I guess one lawyer is just as good as the next lawyer for making such a statement -- and the State of Hawaii does employ lawyers for vetting important official statements (as all states do).
So, the "interim answer" for who makes that determination as to what is meant by "natural born citizen" in the Constitution -- it's a lawyer who is employed by the State of Hawaii, making that statement (you can bet they had lawyers all over that statement... :-) ...). And for the "final answer" as for who makes that determination -- it's the Supreme Court who says what the Constitution means in regards to Obama and this issue of his "natural born status".
