Trespass Ab Initio
Trespass Ab Initio — A Detailed Analysis
1. Meaning / Definition
Trespass Ab Initio literally means “trespass from the beginning.”
It is a legal doctrine in property law which states that:
“A person who enters land lawfully under some legal authority (e.g., a lease, licence, or court order) but subsequently exceeds or abuses that authority, is considered to have been a trespasser from the outset.”
Essence:
Initial entry may be lawful.
Misuse or abuse of authority converts lawful entry into a continuing trespass from the very beginning.
2. Principles of Trespass Ab Initio
Initial Lawful Entry
The entry on the property must initially be lawful (e.g., by a court order, license, or legal possession).
Abuse of Authority
The entrant must abuse the authority under which they entered.
Examples include excessive force, wrongful eviction, illegal use, or exceeding the scope of the order.
Conversion into Trespass
The moment the lawful authority is abused, the law treats the person as if they were a trespasser from the start (ab initio).
Purpose
Protects the property owner from misuse of legal power.
Discourages authorities or licensees from exceeding lawful rights.
3. Common Examples
Police/Officer Example
A police officer enters a house under a warrant for a search.
If the officer uses the opportunity to loot or damage property beyond the search, entry becomes trespass ab initio.
Tenant / Licensee Example
A tenant has lawful possession of a rented property.
If the tenant damages or illegally occupies parts of the property outside lease terms, he may be treated as trespasser ab initio.
Court Orders / Attachment Example
Bailiffs executing a court decree must act within authority.
Excessive or wrongful seizure may render their entry trespass ab initio.
4. Case Law Illustrations
R. v. Amratlal (1907)
Police officer entered premises lawfully but detained goods not authorized by warrant.
Court held: Trespass ab initio applies; officer’s entry treated as trespass from beginning.
Garner v. Strickland (1932)
Tenant lawfully in possession exceeded terms of lease by damaging property.
Court held: Lawful possession converted into trespass ab initio.
Regal (Hastings) Ltd. v. Gulliver (1942)
Directors used company authority for personal gain beyond authority.
Though corporate context, principle: exceeding lawful authority converts initial action into breach of trust/trespass equivalent.
State / Police Authority Cases
Courts in India and UK have repeatedly held that unauthorized acts by lawfully authorized officers make their acts void ab initio (treated as trespass from start).
5. Distinction from Ordinary Trespass
| Feature | Ordinary Trespass | Trespass Ab Initio |
|---|---|---|
| Initial Entry | Always unlawful | Initially lawful |
| Abuse of Authority | Not required | Must exceed authority |
| Legal Effect | Trespass begins at entry | Trespass treated as from the beginning |
| Purpose | Protect property against unauthorized entry | Protect property against abuse of lawful power |
6. Relevance in Modern Law
Police and Administrative Actions

8. Exam-Oriented Key Points

Doctrine discourages misuse of legal rights or public office powers.
Recognized in both common law and Indian law jurisprudence.
Leading principle: Abuse of power invalidates initial legality.
Case laws: R. v. Amratlal (1907), Garner v. Strickland (1932), Regal (Hastings) Ltd. v. Gulliver (1942).
