Show me where the Constitution defines natural-born citizen. Show me where the law defines it. You can't.
What the Ark case said was that a child born in the U.S. was a citizen from the moment of birth, regardless of the nationality of the parents. The Constitution defines only two forms of citizenship - natural born and naturalized. So if you're not naturalized - one who has become a citizen by act of law and not circumstances of birth - then you are natural born. Regardless of whether you call it natural born, citizen at birth, citizen by birth, they all mean the same thing.
I dont have to show you where it is defined. The Court should rule on the definition of the term at the time of the adoption of our Constitution and it hasn’t as of yet. Your case did not address the requirements for POTUS under the Constitution at all.
Actually the Constitution doesn't define either category and therein lies the problem.
Also, just because the Constitution mentions two categories of citizenship it doesn't preclude other categories from exitsting.
However, the Framers and Law of Nations both define natural born as a child born of two citizens.
I’m sure you have already seen this, but read the last 3 paragraphs of the article and you will know what the founders meant.
