The legal system is pretty much the same as the last two games. You don't need to learn about the real life court system to get any ideas of what to expect; this game pretty much speaks for itself. As with the last game, each case after the first has 2 trial days. Your goal in each case is to find the truth and save your clients, but mess up too much and it's GAME OVER.
