""The law of res judicata deals with all of the circumstances in which parties are barred from litigating an issue because of the result of previous litigation. It pervades many areas of the law, both civil and criminal. In the area of criminal law, both double jeopardy and res judicata play a role. Double jeopardy is concerned with how many times the state can prosecute someone for the same offence.There has been an explosion of interest in res judicata in recent years and it is now one of the most rapidly expanding areas of Irish law. This unique book provides an exhaustive guide to this difficult but crucial area of the law.""
