A local stand-up comedian once quipped, "Why do we even have <lowest-level court>? They're always wrong!" It stuck with me because then I read the news and realised they were right! The lowest level court rulings very often get overturned when challenged in higher level courts. Of course, even later, I realised it's just selection bias. Cases are not brought before higher level courts unless in those specific case someone is fairly sure they can get the verdict overturned.
