I have a misdemeanor case and we won in both the first court and the appeal court. I want to understand what the procedure in the cassation court will be like. Will it be the same as the appeal court? Will the cassation court go over each and every piece of evidence like the appeal court? Or will the judge look at it only if there is any misapplication of law? How much time does it typically take in the court of cassation?
