Legal Question in Criminal Law in California

Easily? NO. At all? Not likely. It would require a motion to the convicting court, showing substantial good cause to do so, and convincing the judge it should be done in the interests of justice, over the expected strong objections of the prosecutors. Again, unlikely to happen. However, if serious about hiring counsel to help you in this, and if this is in SoCal courts, feel free to contact me to discuss the facts and costs. .
