Is it a true statement that should Obummer be found to be ineligible to hold the office of the President that everything he did while in office would immediately become null and void?
But how can it stand if he signed it into law illegally?
So FReaking what? A President is not crowned, he takes office on January 20th at noon, after being duly elected. Taking the oath is a requirement, that must be accomplished *before* he can exercise the powers of that office, just as being a Natural born citizen, being 35 or over, and having resided in the US for 14 years are requirements. Taking that oath doesn't unbind him from the Constitutional requirements for holding his office. What if it was found that he was only 30 years old? Or had lived in the US for only 10 years? I'm not saying those things are true, but they would invalidate his election if proved in a court. The House couldn't impeach him because He would not be, or have ever been, President, since he did not meet the Constitutional requirements to hold that office.
Presidents can be affected by Courts while in office, President Clinton was compelled to testify in court, just like any other person may be, and he was later fined $25,000, and disbarred in Arkansas, all while still in office. (Although the initial disbarment, pursuant to a "plea bargin" came the day before he left office. The original disbarrment action had been brought by a committe of the Arkansas Supreme Court. Later, in October of 2001, he was disbarred by the US Supreme Court, probably based on the disbarment in Arkansas)
