In the Vietnamese judicial system, there are two avenues for reviewing a court's final judgment. Under the current procedural legislation, if such judgment can be shown to be based on a serious error of law, it can go through the process of cassation, where the judgment will be reviewed and possibly annulled due to the material error in the procedure. If, on the other hand, new evidence or facts are discovered that could have affected the outcome of the case, the case can be retried.
