Supreme arrogance

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.

By now, it’s well-known that Congress can change the size, and thus the composition, of the Supreme Court by simple legislation. Court-packing, as it’s been called since 1937, when President Franklin Roosevelt unsuccessfully attempted to circumvent a hostile court by expanding its membership, is a deeply controversial practice.

Critically, but less widely understood, the Constitution also grants Congress the power to strip the Supreme Court of its jurisdiction over specific matters.

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.

Justice Felix Frankfurter, an FDR appointee, noted that “Congress need not give this Court any appellate power; it may withdraw appellate jurisdiction once conferred and it may do so even while a case is sub judice.” Chief Justice Warren Burger, whom President Richard Nixon placed on the bench, agreed, writing that Congress could pass simple legislation “limiting or prohibiting judicial review of its directives.”

No less than the executive and legislative branches, the judiciary — particularly, the Supreme Court — is limited in just how much power it can exert. But only if Congress and the president exercise their right to check its power.

"...shall hold their offices during good behavior."

Sam and Clarence have definitely stepped outside that boundary.

Hey, maybe Trump capitalizes according to whatever rules the framers were using.

...but hey, do what you want...you will anyway.
