At the end of a court case, a decision on whether someone is guilty or innocent is made. If a court decides that the defendant is guilty, it proceeds to look at different details of the case to determine the punishment for the crime which may include fines or jail time. When this process is over, the person must begin to serve out their punishment.
Even while someone is in jail, they have a last chance to have their conviction overturned so that they can return to the life that the led before. Criminal appeals court will grant each convicted person at least one appeal on their case and usually no more than one. It is important that these people prepare for these appeals well since they might not get another chance.
