The controversy over Supreme Court nominee Brett Kavanaugh is a time to consider modifying the Judiciary Act of 1789, and end lifetime terms, and change to a maximum of 18 years on the Court for any future Supreme Court Justice.
It would insure in the future that we would have two Supreme Court appointments in any Presidential term, with the limit insuring turnover, rather than locking in a one sided Supreme Court, which can distort constitutional law and interpretation in a detrimental fashion.
Right now, in 2018, we have the danger of locking in a five member right wing Court that could last for 20-30 years, and the Court should, ideally, be a balanced Court, with some liberals, some moderates, and some conservatives, which normally was the way it was most of our history, but now seems a distant dream.
While there is an argument for longer terms, based on specific Justices being considered significant and admired by many, it still makes sense that we have a maximum of 18 years on the Court, and that way, the likelihood of having Justices at advanced ages, in the late 70s and early 80s, is much less likely to occur.
And one must realize that since most Justices come in modern times from the Circuit Courts, it means the average Justice would have a long judicial career, and if coming from an executive or legislative branch background, rare but has occurred in the past, that a Justice’s total career in public service will have been a long one.
