Expert Testimony
An expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as an expert. The judge may consider the witness's specialized (scientific, technical or other) opinion about evidence or about facts before the court within the expert's area of expertise, to be referred to as an "expert opinion". Expert witnesses may also deliver "expert evidence" within the area of their expertise. Their testimony may be rebutted by testimony from other experts or by other evidence or facts. History The forensic expert practice is an ancient profession. For example, in ancient Babylonia, midwives were used as experts in determining pregnancy, virginity and female fertility. Similarly, the Roman Empire recognized midwives, handwriting experts and land surveyors as legal experts. The codified use of expert witnesses and th ...

Common Law
In law, common law (also known as judicial precedent, judge-made law, or case law) is the body of law created by judges and similar quasi-judicial tribunals by virtue of being stated in written opinions."The common law is not a brooding omnipresence in the sky, but the articulate voice of some sovereign or quasi sovereign that can be identified," ''Southern Pacific Company v. Jensen'', 244 U.S. 205, 222 (1917) (Oliver Wendell Holmes, dissenting). By the early 20th century, legal professionals had come to reject any idea of a higher or natural law, or a law above the law. The law arises through the act of a sovereign, whether that sovereign speaks through a legislature, executive, or judicial officer. The defining characteristic of common law is that it arises as precedent. Common law courts look to the past decisions of courts to synthesize the legal principles of past cases. '' Stare decisis'', the principle that cases should be decided according to consistent principled rules so ...

Injury
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts of ...

Blood Analysis
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test, are often grouped together into one test panel called a blood panel or blood work. Blood tests are often used in health care to determine physiological and biochemical states, such as disease, mineral content, pharmaceutical drug effectiveness, and organ function. Typical clinical blood panels include a basic metabolic panel or a complete blood count. Blood tests are also used in drug tests to detect drug abuse. Extraction A venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid (plasma) from the body for analysis. Blood flows throughout the body, acting as a medium that provides oxygen and nutrients to tissues and carries waste products back to the excretory systems for disposal. Conseq ...

Fingerprint
A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Moisture and grease on a finger result in fingerprints on surfaces such as glass or metal. Deliberate impressions of entire fingerprints can be obtained by ink or other substances transferred from the peaks of friction ridges on the skin to a smooth surface such as paper. Fingerprint records normally contain impressions from the pad on the last joint of fingers and thumbs, though fingerprint cards also typically record portions of lower joint areas of the fingers. Human fingerprints are detailed, nearly unique, difficult to alter, and durable over the life of an individual, making them suitable as long-term markers of human identity. They may be employed by police or other authorities to identify individuals who wish to conceal their identity, or to identify people who are incapacitated or deceased and ...

Jury
A jury is a sworn body of people (jurors) convened to hear evidence and render an impartiality, impartial verdict (a Question of fact, finding of fact on a question) officially submitted to them by a court, or to set a sentence (law), penalty or Judgment (law), judgment. Juries developed in England during the Middle Ages and are a hallmark of the English common law system. As such, they are used by the United Kingdom, the United States, Canada, Ireland, Australia, and other countries whose legal systems were derived from the British Empire. But most other countries use variations of the European Civil law (legal system), civil law or Islamic sharia, sharia law systems, in which juries are not generally used. Most trial juries are "petit juries", and usually consist of twelve people. Historically, a larger jury known as a grand jury was used to investigate potential crimes and render indictments against suspects. All common law countries except the United States and Liberia hav ...

Civil Law (common Law)
Civil law is a major branch of the law. Glanville Williams. ''Learning the Law''. Eleventh Edition. Stevens. 1982. p. 2. In common law legal systems such as England and Wales and the United States, the term refers to non- criminal law. The law relating to civil wrongs and quasi-contracts is part of the civil law, as is law of property (other than property-related crimes, such as theft or vandalism). Civil law may, like criminal law, be divided into substantive law and procedural law. The rights and duties of persons (natural persons and legal persons) amongst themselves is the primary concern of civil law. It is often suggested that civil proceedings are taken for the purpose of obtaining compensation for injury, and may thus be distinguished from criminal proceedings, whose purpose is to inflict punishment. However, exemplary damages or punitive damages may be awarded in civil proceedings. It was also formerly possible for common informers to sue for a penalty in civil procee ...

Crime
In ordinary language, a crime is an unlawful act punishable by a State (polity), state or other authority. The term ''crime'' does not, in modern criminal law, have any simple and universally accepted definition,Farmer, Lindsay: "Crime, definitions of", in Cane and Conoghan (editors), ''The New Oxford Companion to Law'', Oxford University Press, 2008 (), p. 263Google Books). though statutory definitions have been provided for certain purposes. The most popular view is that crime is a Category of being, category created by law; in other words, something is a crime if declared as such by the relevant and applicable law. One proposed definition is that a crime or offence (or criminal offence) is an act harmful not only to some individual but also to a community, society, or the state ("a public wrong"). Such acts are forbidden and punishable by law. The notion that acts such as murder, rape, and theft are to be prohibited exists worldwide. What precisely is a criminal offence is de ...

Perjury
Perjury (also known as foreswearing) is the intentional act of swearing a false oath or falsifying an affirmation to tell the truth, whether spoken or in writing, concerning matters material to an official proceeding."Perjury The act or an instance of a person’s deliberately making material false or misleading statements while under oath. – Also termed false swearing; false oath; (archaically forswearing." Like most other crimes in the common law system, to be convicted of perjury one must have had the ''intention'' (''mens rea'') to commit the act and to have ''actually committed'' the act (''actus reus''). Further, statements that ''are facts'' cannot be considered perjury, even if they might arguably constitute an omission, and it is not perjury to lie about matters that are immaterial to the legal proceeding. Statements that entail an ''interpretation'' of fact are not perjury because people often draw inaccurate conclusions unwittingly or make honest mistakes without ...

Penal Law
Criminal law is the body of law that relates to crime. It prescribes conduct perceived as threatening, harmful, or otherwise endangering to the property, health, safety, and moral welfare of people inclusive of one's self. Most criminal law is established by statute, which is to say that the laws are enacted by a legislature. Criminal law includes the punishment and rehabilitation of people who violate such laws. Criminal law varies according to jurisdiction, and differs from civil law, where emphasis is more on dispute resolution and victim compensation, rather than on punishment or rehabilitation. Criminal procedure is a formalized official activity that authenticates the fact of commission of a crime and authorizes punitive or rehabilitative treatment of the offender. History The first civilizations generally did not distinguish between civil law and criminal law. The first written codes of law were designed by the Sumerians. Around 2100–2050 BC Ur-Nammu, the Neo-S ...

Philosophy Of Action
Action theory (or theory of action) is an area in philosophy concerned with theories about the processes causing willful human bodily movements of a more or less complex kind. This area of thought involves epistemology, ethics, metaphysics, jurisprudence, and philosophy of mind, and has attracted the strong interest of philosophers ever since Aristotle's ''Nicomachean Ethics'' (Third Book). With the advent of psychology and later neuroscience, many theories of action are now subject to empirical testing. Philosophical action theory, or the philosophy of action, should not be confused with sociological theories of social action, such as the action theory established by Talcott Parsons. Nor should it be confused with activity theory. Overview Basic action theory typically describes action as intentional behavior caused by an ''agent'' in a particular ''situation''. The agent's ''desires'' and ''beliefs'' (e.g. my wanting a glass of water and believing that the clear liqui ...

Judge
A judge is a person who presides over court proceedings, either alone or as a part of a panel of judges. A judge hears all the witnesses and any other evidence presented by the barristers or solicitors of the case, assesses the credibility and arguments of the parties, and then issues a ruling in the case based on their interpretation of the law and their own personal judgment. A judge is expected to conduct the trial impartially and, typically, in an open court. The powers, functions, method of appointment, discipline, and training of judges vary widely across different jurisdictions. In some jurisdictions, the judge's powers may be shared with a jury. In inquisitorial systems of criminal investigation, a judge might also be an examining magistrate. The presiding judge ensures that all court proceedings are lawful and orderly. Powers and functions The ultimate task of a judge is to settle a legal dispute in a final and publicly lawful manner in agreement with substantial p ...

Tribunal
A tribunal, generally, is any person or institution with authority to judge, adjudicate on, or determine claims or disputes—whether or not it is called a tribunal in its title. For example, an advocate who appears before a court with a single judge could describe that judge as "their tribunal." Many governmental bodies that are titled as "tribunals" are described so in order to emphasize that they are not courts of normal jurisdiction. For example, the International Criminal Tribunal for Rwanda was a body specially constituted under international law; in Great Britain, employment tribunals are bodies set up to hear specific employment disputes. In many (but not all) cases, the word ''tribunal'' implies a judicial (or quasi-judicial) body with a lesser degree of formality than a court, in which the normal rules of evidence and procedure may not apply, and whose presiding officers are frequently neither judges, nor magistrates. Private judicial bodies are also often styled "trib ...
