As a decision can be appealed on a point of law, the appeal is limited in the first instance. However, a person must obtain the leave of the relevant court. Obviously in such circumstances, the judge who heard the case will not have found in favour of the plaintiff. The person who takes the case should be able to appeal. As matters stand, the judge who rejected his or her case can also refuse to allow an appeal.
