1. Core Legal Answer & Context: False imprisonment is a tort that protects an individual's right to personal liberty. It is defined as the complete deprivation of a person's liberty without lawful justification. The statement correctly asserts that while physical confinement is a common form of false imprisonment, it is not the only form. Psychological boundaries or restraint, where a person is made to believe they are not free to leave, can also constitute this tort.

The key elements of false imprisonment are:

• Complete restraint of liberty: The plaintiff must be totally deprived of their freedom of movement in all directions, not just partially obstructed.
• Without lawful justification: The restraint must be unlawful; if there's legal authority (e.g., lawful arrest), it's not false imprisonment.
• Awareness of restraint (debated): While some older cases suggested awareness was necessary, modern jurisprudence, particularly in England, holds that awareness is not strictly essential, though it can be relevant to damages.

Psychological restraint occurs when the plaintiff submits to the defendant's authority or believes, reasonably, that they are not free to leave, even without physical barriers. This can involve threats (express or implied) of force, arrest, or other forms of coercion that compel the plaintiff to stay.

2. Relevant Statutes and Sections: False imprisonment is a common law tort in India, largely uncodified. Principles are derived from English common law and applied by Indian courts. There are no specific statutes or sections in India that define this tort.

3. Important Landmark Cases:

• Bird v Jones (1845) (English): This case established that the restraint must be total. The plaintiff was prevented from going forward on a public highway but was free to go in other directions. The court held that this was not false imprisonment because his liberty was not completely restricted. This case highlights the 'complete restraint' element.
• Meering v Grahame-White Aviation Co. Ltd. (1919) (English): This crucial case affirmed that knowledge of the imprisonment is not essential. The plaintiff was questioned in a room, unaware that two works policemen were stationed outside to prevent him from leaving. The court held that he was falsely imprisoned, stating, "It is a tort of unlawfully depriving a person of his freedom of movement, and it is not necessary that the plaintiff should know that he is being imprisoned." This case strongly supports the idea of psychological restraint, where the plaintiff is not physically confined but is not free to leave due to the defendant's actions or authority.
• Grainger v Hill (1838) (English): In this case, the defendant threatened to arrest the plaintiff if he did not sign a document. The plaintiff signed under duress. The court held that this constituted false imprisonment, as the plaintiff submitted to the defendant's authority due to the threat, even without physical force. This is a clear example of psychological restraint leading to false imprisonment.

4. Clear Conclusion: The critical examination reveals that the statement is largely accurate. While physical barriers are a straightforward way to establish false imprisonment, the tort extends beyond mere physical confinement. Psychological boundaries, where a person is compelled to remain due to submission to authority, threats, or a reasonable belief that they are not free to leave, are indeed sufficient to constitute false imprisonment. The essence of the tort lies in the complete deprivation of liberty without lawful justification, irrespective of whether that deprivation is achieved through physical force or psychological coercion. Cases like Meering and Grainger v Hill underscore this broader interpretation, emphasizing the protection of personal liberty in its fullest sense.
