A historical case for court packing and jurisdiction stripping, from Politico Magazine:

Acting in concert, the president and Congress may shape both the size and purview of the court. They can declare individual legislative measures or entire topics beyond their scope of review. It’s happened before, notably in 1868, when Congress passed legislation stripping the Supreme Court of its jurisdiction over cases related to federal writs of habeas corpus. In the majority decision, Chief Justice Salmon P. Chase acknowledged that the court’s jurisdiction was subject to congressional limitation. Subsequent justices, over the past century, have acknowledged the same.

That’s the brilliance of checks and balances. In the same way that Congress or the Supreme Court can rein in a renegade president, as was the case during Watergate, the president and Congress can place checks on an otherwise unconstrained court, if they believe the justices have exceeded their mandate.
