It seems to me that since the Judicial branch of our Government, and especially referencing the decisions in cases in Federal Court, are where 'the Buck Stops', than that is where government reform should be concentrated:
No law or rule or regulation survives unless the Courts enforce it.
Further, the State Courts, and Laws, eventually bend to the Findings of the Federal Courts. The CONSTITUTION which underpins our government and rights and way of life depends on this process.
But there is a weakness in the present structure. Keeping this short, the fact that the United States Supreme Court is overwhelmed with cases leaves a big gap in the guidance needed to keep the country working within the precepts of the CONSTITUTION. That Honored Tribunal hears about 1% of the cases that hit the Bench each year, and the other Constitution questions go unanswered. This built in uncertainty reverberates all the way down to individual cases in every court and effects even how attorneys behave and enrich themselves.
Most efforts to effect the problem involve placing properly minded Judges in vacated Federal Court offices, mostly at the District court level. There are some 30,000 of them with life long positions, and little Supreme Court guidances on new matters. Each US President attempts to fill vacancies with like-minded persons. Its patch-work, and very susceptible to allowing deviation from proper civil rights to become entrenched over time (Stare-decisis) uncorrected by Supreme Court.
Alternatively, Article III of the CONSTITUTION describes that Congress can establish courts below the Supreme Court as needed.
I propose that a solution to the issue can be having Congress establish a fourth layer of Courts between the Supreme Court and the Circuit Courts. The duty would be to take up the slack for the Supreme Court and hear cases that would otherwise be neglected. The same courts might also be empowered to selectively review decisions of lower courts.
This would trickle down to make all litigation more predictable.
