Actually, it did not overrule a Federal Court. While it is true that Wong Kim Ark did not make a ruling as to what a natural born citizen is, since it was not asked that, the dicta do include a very detailed basis as to why “born here” is sufficient. The Indiana court simply quoted that dicta and made what to it seemed a self-evident conclusion.
It is always possible that the decision could be overruled, but I think the chances of that are pretty close to zero. I know people don't want to believe that, but there's a reason the Supreme Court has passed on the chance to review any of these cases so far.
The Supreme Court will not address this case because they don’t have the authority to remove obama. While they could the define the meaning of Natural born citizen( as in minor vs happensett..CHILDREN WHOM PARENTS ARE U.S. citizens are Natural born)as a separate case,it can not include obama. If the “birther” movement wants to remove obama they need to get the Supreme Court to uphold their previous definitions of Natural Born Citizens. Then they would have the ability to force congress to void obama’s election. NO FIGHT WORTH FIGHTING IS EASY.
