The Supreme Court hasn’t referenced Roman law for determining the meaning of NBC, or for ANY citizenship determinations.
Somewhere in your studying, you should have found out we are not Romans...
“It is an established maxim that birth is a criterion of allegiance. Birth however derives its force sometimes from place and sometimes from parentage, but in general place is the most certain criterion; it is what applies in the United States; it will therefore be unnecessary to investigate any other.”
James Madison, The Founders’ Constitution (1789)
