Actually, for denying a child of a foreign diplomat is a citizen, they could have relied on Wong Kim Ark. A decision that rejects Vattel. BTW - Vattel never mentioned NBC in his writings. It wasn’t MISTRANSLATED that way until 10 years AFTER the US Constitution was written! Vattel used the word “indigenes” - the indigenous people. Not NBC.
Mr Rogers,
Actually, he used the word, “naturels” also. But the fact that “naturels” isn’t identical to “indigenes” is good here: He’s staking out that there is a third type of person, that includes “indigenes” (those whose people are indigenous to a nation) and excludes naturalized citizens, and that is someone who is a “natural-born citizen” despite not being indigenous.
