Criminal law is the body of law that relates to crime. It regulates social conduct and proscribes threatening, harming, or otherwise endangering the health, safety, and moral welfare of people. It includes the punishment of people who violate these laws. Criminal law differs from civil law, whose emphasis is more on dispute resolution and victim compensation than on punishment.
A tort, in common law jurisdictions, is a civil wrong which unfairly causes someone else to suffer loss or harm resulting in legal liability for the person who commits the tortious act, called a tortfeasor. Although crimes may be torts, the cause of legal action is not necessarily a crime as the harm may be due to negligence which does not amount to criminal negligence. The victim of the harm can recover their loss as damages in a lawsuit. In order to prevail, the plaintiff in the lawsuit must show that the actions or lack of action was the legally recognizable cause of the harm. The equivalent of tort in civil law jurisdictions is delict.
Legal injuries are not limited to physical injuries and may include emotional, economic, or reputational injuries as well as violations of privacy, property, or constitutional rights. Torts comprise such varied topics as auto accidents, false imprisonment, defamation, product liability, copyright infringement, and environmental pollution (toxic torts). While many torts are the result of negligence, tort law also recognizes intentional torts, where a person has intentionally acted in a way that harms another, and in a few cases (particularly for product liability in the United States) "strict liability" which allows recovery without the need to demonstrate negligence.
Implied consent is consent which is not expressly granted by a person, but rather inferred from a person's actions and the facts and circumstances of a particular situation (or in some cases, by a person's silence or inaction). The term is most commonly encountered in the context of United States drunk driving laws.
Informed consent is a process for getting permission before conducting a healthcare intervention on a person. A health care provider may ask a patient to consent to receive therapy before providing it, or a clinical researcher may ask a research participant before enrolling that person into a clinical trial. Informed consent is collected according to guidelines from the fields of medical ethics and research ethics. This term was first used in a 1957 medical malpractice case by Paul G. Gebhard.
An informed consent can be said to have been given based upon a clear appreciation and understanding of the facts, implications, and future consequences of an action. In order to give informed consent, the individual concerned must have adequate reasoning faculties and be in possession of all relevant facts at the time consent is given. Impairments to reasoning and judgment which may make it impossible for someone to give informed consent include such factors as basic intellectual or emotional immaturity, high levels of stress such as PTSD or as severe mental retardation, severe mental illness, intoxication, severe sleep deprivation, Alzheimer's disease, or being in a coma.
