My two cents: given the breadth and complexity of modern law, a legal degree (or at least, a bar certification to practice law) should be mandatory for any judicial appointee.

I am currently in the final year of a law degree. When I started my degree, I already had degrees in medicine and information technology, and I'd just founded my third startup.

Despite the legal exposure I'd already obtained as a doctor and entrepreneur, it was humbling to realize just how much about the law I didn't know - not just in terms of actual laws, but also in terms of interpretation of the law as a technical discipline.

For sure, if I'd been appointed as a judge with only my (pre-law degree) experience, I'd have messed up in all sorts of basic and fundamental ways.
