I think the issue you described is present in most all legal systems.
Also, certain aspects are a necessary evil (right to appeal is sacred, as is serious consideration). Money and pingpinging however are valid complaints.
Also, I'd rather have my justice slow (when there's no immidiate harm) and done by humans than by AI. If nothing else, humans can be held accountable. Alternatives cannot. And luckily, the enlightened were on the right track with the model legal system they built.
