Congress doesn't have the Constitutional authority to order a de novo review. Any move by Congress to tell the Courts how to conduct in-court procedures is a direct violation of the Constitution.

Huh? Here's the relevant clause:

In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make.

The Congress can make any exception and regulation of appellate review they so desire.

[Crackingham]

The Congress can make any exception and regulation of appellate review they so desire.

Absolutely false, that passage grants them the power to apply exceptions and regulations to jurisdiction only, not appellate review. Appellate review is not jurisdiction. Those things are completely separate.

[ContraryMary]

That clause deals with jurisdiction only. It does not give Congress the right to tell the Courts HOW to conduct in-court procedures.
