Do you know a woman who is being abused? A legal rights handbook
Can he make excuses to defend himself?
Your partner has the right to decide whether or not to testify. If he chooses to testify, the Crown Attorney will be able to ask him questions. He might try to defend his actions by saying that you started the fight or that he was drunk. This will not excuse his criminal behaviour. He cannot say he was acting in self-defence if he could have protected himself with less force than he used.
It is up to the judge to decide if your partner is guilty.
