Ummm...did you read all the way to the last paragraph?
Michael's lawsuit also seeks a removal of Terri's feeding tube for the third time. The Schindlers' petition asks the judge to allow them to be appointed Terri's guardian in place of Michael.
If this were merely a dispute over the constitutional separation of powers, you might be right.
But the lawsuit includes yet another demand for Terri's death by starvation. The Schindlers do indeed have a dog in that fight.
BTW, in the event that the Schindlers prevail tomorrow (I know the courts are stacked against them, but the Florida statutes make clear that sexual cohabitation with anyone other than a spouse is grounds for removal of guardianship--even when such cohabitation doesn't constitute adultery against the ward) would Michael still have a legitimate case? Or would he no longer be a party to this matter?
