What Is a Criminal Appeal and Why You Need a Lawyer
If you’ve been convicted of a criminal offence, a criminal appeal gives you the chance to ask a higher court to review your case. You can challenge the conviction, the sentence, or both, depending on your circumstances.
A skilled criminal appeal lawyer looks for legal errors made during your trial such as mistakes in applying the law, mishandling of evidence, or unfair procedures. Some appeals proceed automatically, while others require permission from the court, and in certain cases, the Crown may also appeal.
