Defense - sustany/dvg GitHub Wiki
A defense is an act of protecting one�s own interests. In common law, a defendant may use defenses to prevent or limit liability. A defense can either allege a failure to state a claim, or affirm the existence of a claim and present additional reasons that prevent the plaintiff or prosecutor from prevailing on a cause of action, a demand for relief, or otherwise obtaining the result requested. A defense can be founded on both factual and legal grounds.
