In law, strict liability is a standard for liability which may exist in either a criminal or civil context. A rule specifying strict liability makes a person legally responsible for the damage and loss caused by his/her acts and omissions regardless of culpability (including fault in criminal law terms, typically the presence of mens rea). Under strict liability, there is no requirement to prove fault, negligence or intention. Strict liability is prominent in tort law (especially product liability), corporations law, and criminal law.

False imprisonment is an act punishable under criminal law as well as under tort law. (Cornell Law School)

obligation; duty. Broadly speaking, the words are synonymous in referring to what a person is required to do or refrain from doing—or for the performance or nonperformance of which the person is responsible. But there are connotative nuances. An obligation is normally an immediate requirement with a specific reference .

A duty may involve legal compulsion and immediacy, but the word carries an overlay of a moral or ethical imperative . More specifically, duty = (1) that which one is required to do or refrain from doing, esp. as occupant of some position, role, or office; or (2) any one of a complex of rights and standards of care imposed by a legal relationship. Sense 2 appears primarily in tort law, in which writers use duty only to mean that there could be liability. (Garner’s Dictionary of Legal Usage)

An omission is a failure to act, which generally attracts different legal consequences from positive conduct. In the criminal law, an omission will constitute an actus reus and give rise to liability only when the law imposes a duty to act and the defendant is in breach of that duty. In tort law, similarly, liability will be imposed for an omission only exceptionally, when it can be established that the defendant was under a duty to act. (Wikipedia)
