Durable and resilient change means connecting the court expansion to something meaningful. In this case, it would involve looking back on history and returning to the concept that the SC has seats equivalent to the number of federal circuits.
It could be argued there is almost a precedent for this from the Judiciary Act of 1869, the last time the court size changed, and that’s held up after all this time.
Of course. Wikipedia would probably do a better job, but the idea behind it was that the smallest state by population serves as the baseline for representation within the House, which was originally intended to be based on population. At the time it was conceived, this was Wyoming.
This means that representation would be more accurately scaled to the population, so instead of rebalancing which states get larger shares of reps (CA, TX, FL, NY, etc) to accommodate the hard limit of 435, the House continues to grow to meet the demands of the populace. Under the rule, the House would grow well beyond 435 but it would mean one vote in Wyoming wouldn’t be worth roughly 68 votes in California, for example. Instead, CA would gain something like 17 reps and Wyoming would have 1.
Since the only outlined requirements for the House in the Constitution is that each state has one rep and there are not more than one rep per 30,000 citizens, this would require a repeal of the law capping the House at 435 (due to the physical constraints of the building!) and the passing of a new law to expand it. The Wyoming Rule was a proposal to do just that.
