The United States District Court for the Middle District of Florida SHALL have jurisdiction
This establishes the judge can hear it, and he did.
the District Court SHALL determine de novo any claim of a violation of any right of Theresa Marie Schiavo within the scope of this Act
Notice that this DOES NOT direct the federal judge to try the entire case from the beginning, just rule on claims of rights violations without considering prior judgements on whether there were any rights violations. The Schindlers brought IIRC four claims of rights violations, all of which were reviewed de novo, all of which were rejected.
The District Court SHALL entertain and determine the suit without any delay or abstention in favor of State court proceedings,
And the judge did, likely stayed up all night doing it.
So, where did the federal judge violate anything?
It's not "let's read." It's "YOU read." The federal courts did NOT review DE NOVO. Quit spinning and do some reading. tutstar and I have already provided you with plenty; you've more than shown yourself ignorant to the facts. And it now appears you prefer being willfully ignorant and defending murderers and lawbreakers.
