The choices of trial tactics made at the criminal trial may affect the result of the civil action. For example, a man named deBrouwer who was found guilty of assault causing bodily harm against a man named Weber. At his civil trial, he attempted to plead self-defense. He argued that, as he had not led evidence in his defense on the criminal charges, the issue of self-defense had not been considered by the criminal court. The judge presiding at the civil case struck out his statement of defense and ordered that he file an amended statement of defense that stated that he did not take issue with what was decided by the criminal court. See Weber v. deBrouwer, 2009 BCSC 1613.
Other cases have held, however, that a court should usually have something more than a simple certificate at conviction to rely upon. See Smith v. Doucette, 2005 NSSC 327.
