Introduction
Conversion is a civil wrong involving movable property. It occurs when a person wrongfully deals with another’s goods in a way that is inconsistent with the owner’s (or rightful possessor’s) rights and thereby deprives that person of possession or use of the goods.
In simple terms: if A wrongfully takes, keeps, uses, sells, destroys, or otherwise treats B’s goods as if they were his own, A may be liable for conversion.
Meaning of Conversion
Conversion is an intentional dealing with another person’s movable property that seriously interferes with that person’s right to possess it.
The focus is not usually on whether the defendant intended to cause harm, but on whether the defendant intentionally exercised control over the goods in a manner inconsistent with the claimant’s rights.
Essential Elements
The main elements of conversion are:
- Movable property: The subject matter must ordinarily be identifiable movable property or goods.
- Right to possession: The claimant must have a legal right to immediate possession of the goods.
- Wrongful interference: The defendant must exercise control or deal with the goods inconsistently with the claimant’s rights.
- Intentional act: The interference must generally be a voluntary act. It is not necessary to prove an intention to commit a legal wrong.
- Deprivation or serious interference: The conduct must substantially interfere with the claimant’s possession or rights.
- Damage: The claimant must establish the loss or interference caused by the conversion, for which an appropriate remedy may be granted.
Common Forms of Conversion
Conversion may take several forms:
| Form of Conversion | Meaning |
|---|---|
| Taking | Wrongfully taking another person’s goods. |
| Detention | Wrongfully retaining goods after the right to retain them has ended. |
| Wrongful sale | Selling another person’s goods without authority. |
| Wrongful transfer | Transferring goods to another person in denial of the owner’s rights. |
| Wrongful use | Using another person’s goods in a substantially inconsistent manner. |
| Destruction | Wrongfully destroying another person’s goods. |
| Refusal to return goods | A wrongful refusal to return goods to a person entitled to immediate possession. |
Conversion and Trespass to Goods
Although the expressions are sometimes used interchangeably, a useful distinction exists:
- Trespass to goods generally involves a direct and wrongful interference with another’s possession of movable property.
- Conversion is a more serious interference involving an exercise of dominion or control over the goods inconsistent with the claimant’s rights.
Example: Merely touching or moving another’s goods without lawful authority may constitute trespass. Selling, destroying, or wrongfully retaining the goods is more likely to constitute conversion.
Who Can Sue?
A person who has a better right to immediate possession of the goods may bring an action for conversion.
The claimant need not always be the absolute owner. A person having lawful possession or a superior right to possession may also have a claim.
Who Can Be Sued?
Any person who wrongfully exercises control over another’s goods may potentially be liable.
Liability may arise even where the defendant mistakenly believed he had a right to deal with the goods, because conversion focuses on the wrongful interference with the claimant’s possessory rights rather than the defendant’s intention to commit a legal wrong.
Defences
Depending on the facts, the following may provide a defence:
- Consent or authority of the owner or person entitled to possession.
- Lawful possession or lawful authority to deal with the goods.
- Claim of right, where legally recognised.
- Abandonment of the property by its owner.
- Statutory authority or other legal justification.
- Lack of sufficient interference to constitute conversion.
- In appropriate cases, innocent delivery or dealing may affect liability or the remedy.
Remedies
The principal remedies for conversion include:
- Damages: Compensation for the value of the goods and the loss suffered.
- Return of the goods: Where appropriate, the claimant may seek recovery of the goods.
- Compensation for consequential loss: Additional loss flowing from the conversion may be recoverable where legally recognised and properly proved.
Important Indian Judicial Principles
Indian courts have applied the principles of conversion in cases involving wrongful interference with movable property.
- In D. Saxena v. Balram Prasad Sharma (2000) 7 SCC 264, the Supreme Court considered the nature of a lawyer’s lien over a client’s files and held that case files are not goods over which such a lien could be claimed in the circumstances. The decision illustrates the importance of determining the nature of the property and the legal right claimed over it.
- In A. Mathai v. K. V. S. & Co. (2017) 5 SCC 362, the Supreme Court discussed principles relating to conversion and wrongful dealing with property, emphasising that liability depends upon the nature of the interference with another person’s rights.
- In Fouldes v. Willoughby (1841) 8 M & W 540, the English court held that merely removing another person’s goods, without exercising ownership or control over them, did not amount to conversion, though it could constitute trespass to goods.
- In Kuwait Airways Corporation v. Iraqi Airways Co. [2002] 2 AC 883, the House of Lords held that wrongful possession and dealing with another’s aircraft as one’s own amounted to conversion. These cases show that conversion requires a substantial interference with another person’s right to possess or control movable property.
Simple Examples
- A takes B’s laptop without permission and sells it → conversion.
- A borrows B’s camera with permission but refuses to return it after being lawfully asked → may amount to conversion.
- A destroys B’s furniture deliberately without legal authority → conversion.
- A finds goods belonging to B and wrongfully treats them as his own → may constitute conversion.
Conclusion
Conversion protects a person’s possessory and proprietary rights over movable property. It occurs when someone wrongfully exercises control over another’s goods in a manner inconsistent with the rights of the person entitled to them. Taking, selling, destroying, transferring, or wrongfully retaining goods are common examples.
The central question is simple: Has the defendant dealt with the goods in a way that seriously interferes with the claimant’s right to possess them? If so, the law may provide a remedy through damages, recovery of the goods, or other appropriate relief.
