Samuel Alito, The Wall Street Journal, July 28, 2023:
Congress did not create the Supreme Court. [The Constitution did]. I know this is a controversial view, but I’m willing to say it: No provision in the Constitution gives them the authority to regulate the Supreme Court—period.
In the other corner, the United States Constitution, 1787, Article III, Section 2, Clause 2:
In all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party, the supreme Court shall have original Jurisdiction. 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.
