Jurisprudence – From Latin: The term “jurisprudence” means the “science of law”. Statutes articulate the bland rules of law, with only rare reference to factual situations. The actual application of these statutes to facts is left to judges who consider not only the statute but also other legal rules which might be relevant to arrive at a judicial decision; hence, the “science”. Thus, jurisprudence” has come to refer to case law, or the legal decisions which have developed and which accompany statutes in applying the law against situations of fact.
