An important key there is judicial reform. “Reigning in” federal judges is less important that firing many of them. While typically this could be done through impeachment, that is very rare. So an alternative means is the restructuring of the federal judiciary.
This primarily takes two persons, the chairmen of the house and senate judiciary committees. They should consider everything from enlarging the Supreme Court from 9 to 13, and many other structural changes.
And importantly, the zinger is to retire a LOT of radical federal judges by reordering their courts so they no longer have jobs.
They can also kill off much of the “high profit” legal gambits, like class action suits, malpractice, and liability, by limiting the amount lawyers can get in fees. By doing this they could crush a huge number of Barratry oriented leftist legal schemes.
They can repeal the ACLU subsidy of allowing legal costs in lawsuits involving religion. This has been a bounty to scoundrels, mostly suing schools over petty religious expressions.
They can also streamline the death penalty both at the federal level and in federal appeals from the states. These would in no way make the system unfair, just make it so that federal judges opposed to the death penalty cannot drag out such cases for decades.
Without looking at my handy dandy pocket Constitution on my desk, I think it would take a Constitutional Amendment to limit their terms and/or enforce them to judge by "original intent", which is THE biggest problem with the Supreme Court and State courts regarding their own State Constitutions, not to mention appellate regional courts. Talk about a run on sentence.
There is no solution other than a Constitutional Amendment, and I'm all for it. The USSC has TOO much power and so often make their decisions within their own bias and past ill-conceived precedence rather than "original intent".
Personally, I think the the Executive Branch should have more limitations even more than the Judiciary Branch. Third on my list after "term limits" and "reduced Congressional sessions.
