Such a proposal isn’t unconstitutional, nor even that radical. There’s nothing sacred about the number nine, which isn’t found in the constitution and instead comes from an 1869 act of congress. Congress can pass a law changing the court’s size at any time. That contrasts it with other potentially meritorious reform ideas, like term limits, which would require amending the constitution and thus are unlikely to succeed. And countries, with much smaller populations, have much larger high courts. In 1869, when the number nine was chosen, the U.S. was roughly a tenth of its current size, laws and government institutions were far smaller and less complex, and the volume of cases was vastly lower. Supreme Court enlargement only seems radical because we have lost touch with the fundamentals of our living, breathing constitution. The flawed debate over court-packing is an opportunity to reexamine our idea of what a Supreme Court is, and some foundational, and wrong, assumptions.
