Jurisprudence is the philosophy and theory of law. It is concerned primarily with what the law is and what it ought to be. That includes questions of how persons and social relations are understood in legal terms, and of the values in and of law. Work that is counted as jurisprudence is mostly philosophical, but it includes work that also belongs to other disciplines, such as sociology, history, politics and economics.
Philosophy of law is a branch of philosophy that examines the nature of law and law's relationship to other systems of norms, especially ethics and political philosophy. It asks questions like "What is law?", "What are the criteria for legal validity?", and "What is the relationship between law and morality?" Philosophy of law and jurisprudence are often used interchangeably, though jurisprudence sometimes encompasses forms of reasoning that fit into economics or sociology.
A statute of limitations, known in civil law systems as a prescriptive period, is a law passed by a legislative body to set the maximum time after an event within which legal proceedings may be initiated. In most jurisdictions, such periods exist for both criminal law and civil law such as contract law and property law, though often under different names and with varying details.
A will and testament is a legal document that expresses a person's (testator) wishes as to how their property (estate) is to be distributed after their death and as to which person (executor) is to manage the property until its final distribution. For the distribution (devolution) of property not determined by a will, see inheritance and intestacy.
A writ of prohibition is a writ directing a subordinate to stop doing something the law prohibits. This writ is often issued by a superior court to the lower court directing it not to proceed with a case which does not fall under its jurisdiction.
Legal positivism is a school of thought of analytical jurisprudence developed largely by legal philosophers during the 18th and 19th centuries, such as Jeremy Bentham and John Austin. While Bentham and Austin developed legal positivist theory, empiricism provided the theoretical basis for such developments to occur. The most prominent legal positivist writer in English has been H. L. A. Hart.
Legal realism is a naturalistic approach to law; it is the view that jurisprudence should emulate the methods of natural science, that is, it should rely on empirical evidence. Hypotheses must be tested against observations of the world.
Ronald Myles Dworkin was an American legal philosopher, jurist, and scholar of United States constitutional law. At the time of his death, he was Frank Henry Sommer Professor of Law and Philosophy at New York University and Professor of Jurisprudence at University College London. Dworkin had taught previously at Yale Law School and the University of Oxford, where he was the Professor of Jurisprudence, successor to philosopher H.L.A. Hart.
Legal formalism is both a descriptive theory and a normative theory of how judges should decide cases. In its descriptive sense, formalists maintain that judges reach their decisions by applying uncontroversial principles to the facts; formalists believe that there is an underlying logic to the many legal principles that may be applied in different cases. These principles, they claim, are straightforward and can be readily discovered by anyone with some legal expertise. Supreme Court Justice Oliver Wendell Holmes Jr., by contrast, believed that "The life of the law has not been logic: it has been experience". The formalist era is generally viewed as having existed from the 1870s to the 1920s, but some scholars deny that legal formalism ever existed in practice.
Lon Luvois Fuller was an American legal philosopher best known as a proponent of a secular and procedural form of natural law theory. Fuller was a professor of law at Harvard Law School for many years, and is noted in American law for his contributions to both jurisprudence and the law of contracts. His debate in 1958 with the prominent British legal philosopher H. L. A. Hart in the Harvard Law Review was important in framing the modern conflict between legal positivism and natural law theory. In his widely discussed 1964 book The Morality of Law, Fuller argues that all systems of law contain an "internal morality" that imposes on individuals a presumptive obligation of obedience. Robert S. Summers said in 1984: "Fuller was one of the four most important American legal theorists of the last hundred years".
Gertz v. Robert Welch, Inc., 418 U.S. 323 (1974), was a landmark decision of the US Supreme Court establishing the standard of First Amendment protection against defamation claims brought by private individuals. The Court held that, so long as they do not impose liability without fault, states are free to establish their own standards of liability for defamatory statements made about private individuals. However, the Court also ruled that if the state standard is lower than actual malice, the standard applying to public figures, then only actual damages may be awarded.
The slayer rule, in the U. S. law of inheritance, stops a person inheriting property from a person they murdered.
The plain meaning rule, also known as the literal rule, is one of three rules of statutory construction traditionally applied by English courts. The other two are the "mischief rule" and the "golden rule".
The mischief rule is one of three rules of statutory interpretation traditionally applied by English courts, the other two being the "plain meaning rule" and the "golden rule". It is used to determine the exact scope of the "mischief" that the statute in question has set out to remedy, and to guide the court in ruling in a manner which will "suppress the mischief, and advance the remedy".
"The Case of the Speluncean Explorers" is an article by legal philosopher Lon L. Fuller first published in the Harvard Law Review in 1949. Largely taking the form of a fictional judgment, it presents a legal philosophy puzzle to the reader and five possible solutions in the form of judicial opinions that are attributed to judges sitting on the fictional "Supreme Court of Newgarth" in the year 4300.
Hanna v. Plumer, 380 U.S. 460 (1965), was a decision by the Supreme Court of the United States, in which the Court further refined the Erie doctrine regarding when and by what means federal courts are obliged to apply state law in cases brought under diversity jurisdiction. The question in the instant case was whether Federal Rules of Civil Procedure governing service of process should yield to state rules governing the service of process in diversity cases. The Court ruled that under the facts of this case, federal courts shall apply the federal rule. The decision was drafted by John Hart Ely, who was then a law clerk for Earl Warren.
The Hart–Fuller debate is an exchange between the American law professor Lon L. Fuller and his English counterpart H. L. A. Hart, published in the Harvard Law Review in 1958 on morality and law, which demonstrated the divide between the positivist and natural law philosophy. Hart took the positivist view in arguing that morality and law were separate. Fuller's reply argued for morality as the source of law's binding power.
The Hart–Dworkin debate is a debate in legal philosophy between H. L. A. Hart and Ronald Dworkin. At the heart of the debate lies a Dworkinian critique of Hartian legal positivism, specifically, the theory presented in Hart's book The Concept of Law. While Hart insists that judges are within bounds to legislate on the basis of rules of law, Dworkin strives to show that in these cases, judges work from a set of "principles" which they use to formulate judgments, and that these principles either form the basis, or can be extrapolated from the present rules.
Henry Melvin Hart Jr. (1904–1969) was an American legal scholar. He was an influential member of the Harvard Law School faculty from 1932 until his death in 1969.
Law's Empire is a 1986 text in legal philosophy by Ronald Dworkin, in which the author continues his criticism of the philosophy of legal positivism as promoted by H.L.A. Hart during the middle to late 20th century. The book introduces Dworkin's Judge Hercules as an idealized version of a jurist with extraordinary legal skills who is able to challenge various predominating schools of legal interpretation and legal hermeneutics prominent throughout the 20th century. Judge Hercules is eventually challenged by Judge Hermes, another idealized version of a jurist who is affected by an affinity to respecting historical legal meaning arguments which do not affect Judge Hercules in the same manner. Judge Hermes' theory of legal interpretation is found by Dworkin in the end to be inferior to the approach of Judge Hercules.
