Courts are usually the last vestiges of authoritarian power in democracies, having to rely on the authority of life-long (and politically) appointed supreme court judges after all recourses have been tried and done (which for you may not be many if you don’t have a wealth of cash), and they are at their worst when tied to money, power, and lack of public transparency. Most countries don’t even have jury systems in their courts and you can’t represent yourself within it. The predominance of mafias in Italy and their spread internationally is more than a hint of how ineffective and biased they can be.
