Excellent analysis. The Constitution gives the Congress explicit authority to limit the jurisdiction of the Federal judiciary, and it is high time that they did.

However, limiting the power of the Supreme Court itself would likely take a Constitutional Amendment. The authority of Congress is limited to federal courts lower than the Supreme Court.

To wit: The judicial power of the United States, shall be vested in one Supreme Court, and in such inferior courts as the Congress may from time to time ordain and establish. Article 3, Sec. 1

The implication is that the Supreme Court does not fall under the purview of the Congress.
