Which term describes the illegal confinement of a person without their consent?

The term that describes the illegal confinement of a person without their consent is false imprisonment. This involves restraining an individual's freedom of movement without legal authority or the person's consent. It can occur through physical barriers, such as locking someone in a room, or through threats or intimidation that prevent a person from leaving a location.

False imprisonment does not require the use of force; rather, it is based on the lack of consent and the unlawful nature of the confinement. The focus is on the violation of personal liberty, where an individual is detained against their will.

Other terms in the list, while related to unlawful control or confinement, do not specifically fit the legal definition of false imprisonment. Kidnapping involves the unlawful taking away or transportation of a person against their will, often with the intent to hold them for ransom or exert some similar form of control. Assault refers to causing fear of imminent harm in another, and unlawful detainment can be a broader term that may include acts similar to false imprisonment but might not capture the legal specificity that false imprisonment provides.
