How about this, did the court throw the cast out because there is not such person as Soetoro? That would have been the easiest route to go but if they didn’t then such a person exists. If Soetoro exists, then the usurper used other names which is not what he swore to on his bar application. That also brings into question the adoption and the Indonesian citizenship again.
Why would that be the easiest route, or even necessary? The judge had no problem finding reasons to dismiss the case without even going into whether the defendants name was Obama or Soetoro. The original ruling is here.
