I don't get the outrage.
This is law. It takes ten years of practice just to really scratch the surface in one small area of law. Arbitrary compulsive retirements (such freedom) serve only to cause brain and experience drain that cannot be easily made up.
Add to that, most people retire when they should all on their own. Maybe sometimes they need a little push from colleagues. Very rarely does it rise to the level of publis inquest and a forced competency exam.
This time it seems it did, and look! It's happening. What's the real problem? Why is throwing the baby out with the bath water seen as a legit solution?
I prefer government officials, and especially judges and senators, to have real experience. Most elders are not senile old coots, especially not those who spent their lifetime in a career that by nature is as daily taxing on memory and recall as is the law. Some say the law is a study and a practice in memory. The best trial lawyers usually have the best memory. Add to that the extensive amount of reading and writing trial attorneys and judges do. It's not like this judge has been clocking out from a show-up job every day at 5 pm and then doom scrolling or binging Netflix.
I would say of the judges I've been before including some elderly federal judges in a senior or retired judge, or magistrate sort of role, have been some of the most knowledgeable, most efficient judges I've argued to, especially at the appellate level, where all they do (in theory) is jurisprudence, logical and policy reasoning, and interpretation, the most mentally demanding sort of law practice.
