## Facts

- A Mercedes-Benz was stolen from an auto dealer.
- The dealer’s insurer, Liberty Mutual Insurance Company, paid the theft loss and became subrogated to the dealer’s rights to the vehicle.
- Theodore Zadlo brought the Mercedes to Richard Iacomini’s garage, falsely representing that he owned the car.
- Iacomini performed substantial repair work and retained the vehicle, seeking payment for repairs and storage.
- Police later determined the vehicle was stolen and notified Iacomini and Liberty Mutual.
- Liberty Mutual demanded possession; Iacomini refused to release the car unless compensated.
- Liberty Mutual filed a replevin action in district court and obtained a writ of replevin; the court also ordered Liberty Mutual to hold the vehicle for at least 90 days to allow Iacomini to file an action for repair costs.
- Within the 90-day period, Iacomini sued Liberty Mutual in superior court and moved to specify/amend his claim to add unjust enrichment; the trial court denied the motion.
- Iacomini appealed, challenging (1) the refusal to recognize a lien and (2) the denial of his effort to assert unjust enrichment.

## Issues

1. Whether a statutory motor vehicle mechanic’s lien under RSA 450:1–2 can attach against the true owner (or subrogated insurer) when repairs were ordered by a non-owner of a stolen vehicle without the owner’s knowledge or consent.
2. Whether a common-law mechanic’s lien can arise against the true owner under the same circumstances.
3. Whether the repairman may pursue equitable relief (unjust enrichment/restitution and possibly an equitable lien) based on improvements to the owner’s property.
4. Whether the trial court abused its discretion by denying a timely motion to add an unjust-enrichment claim when the court had provided a 90-day window to assert such a claim.

## Decision

- The court held that no statutory mechanic’s lien arose because statutory requirements must be strictly met and a lien cannot be created against an owner without the owner’s knowledge, acquiescence, or consent.
- The court held that no common-law mechanic’s lien arose because such liens require owner authorization or consent, which is absent when repairs are commissioned by a possessor of stolen property.
- The court ruled that equitable relief based on unjust enrichment may be available if the owner (or subrogated insurer) received a benefit that would be unconscionable to retain without compensation.
- The court concluded the trial court abused its discretion by denying Iacomini’s motion to specify/amend to assert unjust enrichment when filed within the 90-day period contemplated by the earlier order.
- The judgment was affirmed in part and reversed in part, and the case was remanded to permit litigation of the unjust-enrichment theory.

## Legal Principles

- Statutory liens are strictly construed; the claimant must satisfy the statute’s requisites.
- Under RSA 450:1–2, a motor vehicle repair lien cannot be created against the owner without the owner’s knowledge, acquiescence, or consent.
- A common-law mechanic’s lien for repairs arises only if the owner (or an authorized person) requested or consented to the work; no such lien arises against the owner of a stolen vehicle repaired at the request of an unauthorized possessor.
- Statutory motor vehicle liens supplement, rather than replace, common-law mechanic’s lien doctrines.
- A court may order restitution for unjust enrichment in the absence of contract when a defendant received a benefit that would be unconscionable to retain.
- In unjust enrichment, damages focus on the value of the benefit received by the defendant, not the plaintiff’s cost.
- An equitable lien may be imposed to prevent unjust enrichment for the increased value conferred on the owner’s property.

## Conclusion

A garageman who repairs a stolen vehicle at a non-owner’s request acquires no statutory or common-law lien against the true owner or its subrogated insurer absent owner consent, but the repairman may pursue restitution for unjust enrichment (and potentially an equitable lien) measured by the benefit conferred; denying a timely amendment to plead unjust enrichment within a court-ordered filing window is an abuse of discretion.
