If the judgment has taken effect, reversing the case is an application for retrial, which is also called a complaint. The appeal was lodged with the court of first instance. If you are not satisfied with the judgment of the court of first instance, you can appeal to a higher court. Generally speaking, the appeal should have new evidence or new defense reasons, otherwise the appeal will be difficult and the probability of cassation will be below 5%.
