There are apparently a couple articles out there ranking California’s courts, and its Supreme Court, tops in the nation . . . whatever that means. I say “apparently” because I have to take others’ words for it. I’m way too busy to read the articles themselves.
One nugget I gleaned in my quick skim of the more recent article: while the first study ranked California’s Supreme Court #1 in influence on other states, a survey by the U. S. Chamber of Commerce (PDF download) rated the California court system as a whole as only 44th best (or 7th worst, depending on how you look at it) in the nation. Go figure.
