“What happens if someone doesn't want to tell the court what they know”
If you were a witness in a trial, you used to have to follow certain rules about giving evidence. However, these rules have changed. The old law that talked about what happened if a witness refused to give evidence doesn’t apply anymore. It was removed on 1 July 2013. This means that if you’re asked to be a witness now, different rules might apply. If you want to know more about being a witness today, you should look at newer laws or ask a lawyer.
