Erie doctrineThe Erie doctrine is a fundamental legal doctrine of civil procedure in the United States which mandates that a federal court called upon to resolve a dispute not directly implicating a federal question (most commonly when sitting in diversity jurisdiction, but also when applying supplemental jurisdiction to claims factually related to a federal question or in an adversary proceeding in bankruptcy) must apply state substantive law. The doctrine follows from the Supreme Court landmark decision in Erie Railroad Co.
Duty of careIn tort law, a duty of care is a legal obligation that is imposed on an individual, requiring adherence to a standard of reasonable care to avoid careless acts that could foreseeably harm others, and lead to claim in negligence. It is the first element that must be established to proceed with an action in negligence. The claimant must be able to show a duty of care imposed by law that the defendant has breached. In turn, breaching a duty may subject an individual to liability.
Ratio decidendiRatio decidendi (Latin plural rationes decidendi) is a Latin phrase meaning "the reason" or "the rationale for the decision". The ratio decidendi is "the point in a case that determines the judgement" or "the principle that the case establishes". In other words, ratio decidendi is a legal rule derived from, and consistent with, those parts of legal reasoning within a judgment on which the outcome of the case depends. It is a legal phrase which refers to the legal, moral, political and social principles used by a court to compose the rationale of a particular judgment.
Construction lawConstruction law is a branch of law that deals with matters relating to building construction, engineering, and related fields. It is in essence an amalgam of contract law, commercial law, planning law, employment law and tort. Construction law covers a wide range of legal issues including contract, negligence, bonds and bonding, guarantees and sureties, liens and other security interests, tendering, construction claims, and related consultancy contracts.
LawyerA lawyer is a person who practices law. The role of a lawyer varies greatly across different legal jurisdictions. A lawyer can be classified as an advocate, government lawyer, attorney, barrister, canon lawyer, civil law notary, counsel, counselor, solicitor, legal executive, or public servant — with each role having different functions and privileges. Working as a lawyer generally involves the practical application of abstract legal theories and knowledge to solve specific problems.
Legal technicalityThe term legal technicality is a casual or colloquial phrase referring to a technical aspect of law. The phrase is not a term of art in the law; it has no exact meaning, nor does it have a legal definition. In public perception, it typically refers to "procedural rules that can dictate the outcome of a case without having anything to do with the merits of that case." However, as a vague term, the definition of a technicality varies from person to person, and it is often simply used to denote any portion of the law that interferes with the outcome desired by the user of the term.
Law reportLaw reports or reporters are series of books that contain judicial opinions from a selection of case law decided by courts. When a particular judicial opinion is referenced, the law report series in which the opinion is printed will determine the case citation format. Historically, the term reporter was used to refer to the individual persons who actually compile, edit, and publish such opinions. For example, the Reporter of Decisions of the Supreme Court of the United States is the person authorized to publish the Court's cases in the bound volumes of the United States Reports.
Decretum GratianiThe Decretum Gratiani, also known as the Concordia discordantium canonum or Concordantia discordantium canonum or simply as the Decretum, is a collection of canon law compiled and written in the 12th century as a legal textbook by the jurist known as Gratian. It forms the first part of the collection of six legal texts, which together became known as the Corpus Juris Canonici. It was used as the main source of law by canonists of the Roman Catholic Church until the Decretals, promulgated by Pope Gregory IX in 1234, obtained legal force, after which it was the cornerstone of the Corpus Juris Canonici, in force until 1917.
Child supportChild support (or child maintenance) is an ongoing, periodic payment made by a parent for the financial benefit of a child (or parent, caregiver, guardian) following the end of a marriage or other similar relationship. Child maintenance is paid directly or indirectly by an obligor to an obligee for the care and support of children of a relationship that has been terminated, or in some cases never existed. Often the obligor is a non-custodial parent. The obligee is typically a custodial parent, a caregiver, or a guardian.
Friedrich Carl von SavignyFriedrich Carl von Savigny (21 February 1779 – 25 October 1861) was a German jurist and historian. Savigny was born at Frankfurt am Main, of a family recorded in the history of Lorraine, deriving its name from the castle of Savigny near Charmes in the valley of the Moselle. Left as orphan at the age of 13, Savigny was brought up by a guardian until, in 1795, he entered the University of Marburg, where, though in poor health, he studied under Professors Anton Bauer and Philipp Friedrich Weiss, the former a pioneer in the reform of the German criminal law, the latter distinguished for his knowledge of medieval jurisprudence.
