And "determining" that a child born to an alien parent is in fact a "Natural Born Citizen" came from what SCOTUS holding?
As I've said several times, there is no SCOTUS holding either way, but there is a strong, well-considered dictum, supported by much historical eveidence, that a child born on U.S. soil to two alien parents is a natural born citizen, and the Indiana court followed that-- which is what any court would do.
