It is no surprise that when someone is found guilty of a criminal offence they are rarely happy. A successful appeal of a conviction or sentence has to be grounded on an error of law. Did the trial judge apply the law incorrectly? Did the judge give the jury the wrong law? That the complainant was lying or the officer had it in for you, may not be enough to overturn the decision. If you wish to appeal the sentence, the question is whether the sentence that was given to you was very high, that it did not take into account mitigating facts, that is facts that were positive about you, such as you pled guilty, that you turned your life around after you were charged or that you made restitution, or your sentence was higher than your co-accused.
These are some of the issues that may support an appeal. However, an appeal court may not overturn the conviction and/or sentence despite these legal issues.
