Bzzzzt. Wrong.

The mere possibility that a question of federal law might arise is being sufficient to satisfy the "arising under"
jurisdictional authorization of Article III [Marbury v. Madison, 1 Cranch 137, 177 (1803), Chief Justice Marshall].
And THAT should have removed the insect-brain Pinellas Nazi Magistrate Judge.

You are correct about that part. If that was all Congress had done there would've been no problem. What they did was go a step further and dictate how the actual legal proceeding would be conducted in court. That's a violation of the separation of powers.
