You've not stated an argument I can understand for your claim of unconstitutionality. You cite Art III for the proposition, I think that the federal courts have power unrelated to Congress's power to authorize it, which is simply not what it says. Here, however, we are dealing with a state court decision, and Congress is using the same Art. III power it has to establish these courts, to expand their jurisdiction, and you say that's not constitutional. Yet, Congress does this all the time. Look at the federal rules for civil procedure, as a simple example. And if there is federal authority, Congress is a legitimate branch of government and is certainly free to legislate in this regard. And the 8th and 14th amendments, as well as Art. III, are the basis for their action. Calling it a private bill is meaningless and of no consequence constitutionally. And then, to top it off, you argue for, or someone does, judicial review, presumably to explain the courts' right to have the final say, when judicial review is nowhere to be found in the federal constitution. You can't have it both ways.
