Intention (criminal law)In criminal law, intent is a subjective state of mind (mens rea) that must accompany the acts of certain crimes to constitute a violation. A more formal, generally synonymous legal term is scienter: intent or knowledge of wrongdoing. Intent is defined in English law by the ruling in R v Mohan [1976] QB 1 as "the decision to bring about a prohibited consequence" (malum prohibitum). A range of words represents shades of intent in criminal laws around the world.
Mens reaIn criminal law, mens rea (ˈmɛnz_ˈreːə; Law Latin for "guilty mind") is the mental state of a defendant who is accused of committing a crime. In common law jurisdictions, most crimes require proof both of mens rea and actus reus ("guilty act") before the defendant can be found guilty. The standard common law test of criminal liability is expressed in the Latin phrase actus reus non facit reum nisi mens sit rea, i.e. "the act is not culpable unless the mind is guilty".
Cause of actionA cause of action or right of action, in law, is a set of facts sufficient to justify suing to obtain money or property, or to justify the enforcement of a legal right against another party. The term also refers to the legal theory upon which a plaintiff brings suit (such as breach of contract, battery, or false imprisonment). The legal document which carries a claim is often called a 'statement of claim' in English law, or a 'complaint' in U.S. federal practice and in many U.S. states.
Strict liabilityIn criminal and civil law, strict liability is a standard of liability under which a person is legally responsible for the consequences flowing from an activity even in the absence of fault or criminal intent on the part of the defendant. Under the strict liability law, if the defendant possesses anything that is inherently dangerous, as specified under the "ultrahazardous" definition, the defendant is then strictly liable for any damages caused by such possession, no matter how careful the defendant is safeguarding them.
Proximate causeIn law and insurance, a proximate cause is an event sufficiently related to an injury that the courts deem the event to be the cause of that injury. There are two types of causation in the law: cause-in-fact, and proximate (or legal) cause. Cause-in-fact is determined by the "but for" test: But for the action, the result would not have happened. (For example, but for running the red light, the collision would not have occurred.) The action is a necessary condition, but may not be a sufficient condition, for the resulting injury.
Legal fictionA legal fiction is a fact assumed or created by courts, which is then used in order to help reach a decision or to apply a legal rule. The concept is used almost exclusively in common law jurisdictions, particularly in England and Wales. A legal fiction typically allows the court to ignore a fact that would prevent it from exercising its jurisdiction by simply assuming that the fact is different. In cases where the court must determine whether a standard has been reached, such as whether a defendant has been negligent, the court frequently uses the legal fiction of the "reasonable man".
DefamationDefamation, at a first approximation, is any form of communication that can injure a third party's reputation. This can include all modes of human-understandable communications: gestures, images, signs, words. It is not necessarily restricted to making assertions that are falsifiable, and can extend to concepts that are more abstract than reputation - like dignity and honour. For a communication to be considered defamatory, it must be conveyed to someone other than the defamed.
Medical malpracticeMedical malpractice is a legal cause of action that occurs when a medical or health care professional, through a negligent act or omission, deviates from standards in their profession, thereby causing injury or death to a patient. The negligence might arise from errors in diagnosis, treatment, aftercare or health management. An act of medical malpractice usually has three characteristics. Firstly, it must be proven that the treatment has not been consistent with the standard of care, which is the standard medical treatment accepted and recognized by the profession.
Law of agencyThe law of agency is an area of commercial law dealing with a set of contractual, quasi-contractual and non-contractual fiduciary relationships that involve a person, called the agent, that is authorized to act on behalf of another (called the principal) to create legal relations with a third party. Succinctly, it may be referred to as the equal relationship between a principal and an agent whereby the principal, expressly or implicitly, authorizes the agent to work under their control and on their behalf.
CulpabilityIn criminal law, culpability, or being culpable, is a measure of the degree to which an agent, such as a person, can be held morally or legally responsible for action and inaction. It has been noted that the word, culpability, "ordinarily has normative force, for in nonlegal English, a person is culpable only if he is justly to blame for his conduct". Culpability therefore marks the dividing line between moral evil, like murder, for which someone may be held legally responsible, and a randomly occurring event, like naturally occurring earthquakes or naturally arriving meteorites, for which no human can be held responsible.
