The NRO link above is to an update of the whole legal situation. This is about the best I've read.
Hat tip: Bill.
A further thought: as opined here previously, this case is only controversial because of the persistent denial of fact by Ms. Schiavo's husband, such as he is, his attorney, the judge, and others who are NOT disinterested parties, yet present themselves as such. It's a web of deceit. The free admission of facts for the record would spell the demise of these people.
