If you consider that there has been a grave error in the judicial process and that this can be assumed to have affected the outcome of a case, you can lodge a complaint founded on grave procedural error. Simply put, a grave error in the judicial process means a very serious error by a court in applying the rules that govern the court’s handling of a process. One example is a party not having received case material that was significant in the trial.
The Supreme Court approves only a very small percentage of all grave procedural error complaints it receives.
