The federal courts and the Supreme Court all need an overhaul. The circuit courts have actually needed an overhaul for years because of workload issues. I think these courts were last adjusted when the US had a population of around 220 million. Our population is now over 330 million and population shifts have changed the workloads for several courts, making cases take years for resolution, sometimes more than five years, which is not justice.
We most likely need more justices on some circuit courts and perhaps fewer or no changes on others, such as those that cover rural states that have lost population. We might even need to add a couple of new circuit courts to balance the populations covered.
As for the Supreme Court, they have been doing far too much ruling through docket cases, partially because they take so few cases for full review. I believe the court should be expanded to 13 justicesone for each of our 13 federal circuit courts. Even if the number of circuit courts is expanded, one justice could most likely handle two of the courts with less populous states rather than expanding the SC to 15.
Obviously, we need the House and Senate to do this, and if we keep the majority it needs to happen next year to give time for a bunch of new appointments. I remember reading some time ago that an analysis of the workloads in some of the busiest circuit courts had already been made (not the one Biden ordered), with requests for additional justices. Im sure each of those courts has an idea for how many justices they need.
The will to do this by Congress is a big question mark.
