2. Ask for a new trial. If you believe that you have new evidence that could change the outcome of your case, you can ask the judge for a new trial. The judge will consider whether the new evidence is material (i.e., relevant and likely to change the outcome of the case) and whether it could not have been discovered with reasonable diligence before the trial. If the judge finds that the new evidence meets these requirements, he or she can order a new trial.
3. Seek post-conviction relief. If you have already been convicted of a crime, you can seek post-conviction relief from the court. This can include a variety of remedies, such as a new trial, a reduced sentence, or even release from prison. Post-conviction relief is typically only available if you can show that you have been denied a fundamental constitutional right.
