If Fukinos declaration is valid then it follows that she saw/knows Obamas parents, mother and father, were USA citizens. That doesnt fit with Obamas declaration of who his father was.
Current US law defines a “Citizen of the United States at birth” as “a person born in the United States and subject to the jurisdiction thereof.” No court has ever ruled that there is a distinction between a “natural born citizen” and a “Citizen of the United States at birth.”
If there was such a distinction, there is no way that the Chief Justice of the United States would have agreed to administer the Oath of Office to an ineligible president-elect.
In my experience with law, codification cannot nullify the law. In this case the law is the words of the Constitution which explicitly demands a “natural born citizen’.
My understanding is that the SCOUSA has never specifically heard arguments on eligibility because of the standing issue. It could well be that justices in their own privy do not agree with doubts as to eligibility.
A’citizen of the USA’ is not,at least by wording, identical to a’natural born citizen of the USA. , and
I have references to prominent judges and office holders since mid 1800s who have made distinction for natural born citizen being of place and parents. I’ll check as to court opinions.
AS to the Chief Justice of USASC being infallible in administering the oath, I was appalled that the oath was made twice because of error during the first; which error it seems to me should have been publicly corrected and not in a private ceremony. My scepticism of judges does not agree with your trust in them.
