This reinforces my idea that you should always go with an advisor who doesn't have this kind of clout. Not that you should have known this ahead of time or you did anything wrong, but I have heard sad stories from large labs enough to be thankful for avoiding them in the past, and it's the advice I will pass on in the future.
I think if you wanted to get at the actual problem and a solution to it, I would say the problem is sad narcissistic jerks aiming to become kings of their research kingdoms, and then they act as tyrants when they get a hold of large sums of grant money. That may be the experience some people have had.
A solution to this that you may like if you want more oversight may be to treat a research lab more like a corporation with a board of directors (I can hear the researchers recoiling) or some other governing body over the lab and the students itself. What do you think of that idea?
Rule by committee. So many examples of that working out great.
How about keeping the apprenticeship aspect just having more masters? One year of just comprehend exams, one year where you’re supposed to devote half your time to research with an advisor and half to comps, and three years where you work on six different projects with different advisors in six month chunks? Some of those will be written up as failures, but basically you end up with 3+ Master’s theses. That’s a great deal more love research academia than legal academia and they don’t seem to lack for scholarly work or impact.
We are apparently talking about very different kinds of professors at very different kinds of institutions.
Unless he were to actually commit a crime, I don't think there is anything my ex-boss could have possibly done which could have ended up with him being removed from his post. He was simply too important to the institution in terms of his reputation and his ability to attract external funding.
How he treated his students was really neither here nor there, as long as the money and the citations kept rolling in.
