Question 1
Nadia returned from vacation to find that a neighbor had taken her lawn mower from her shed and used it to mow his lawn. The mower was back in the shed, but the starter cord was frayed and the mower would not start. Nadia had to pay $60 to replace the cord. Nadia sued the neighbor.
Which claim is most strongly supported by these facts?
- Negligence, because the neighbor failed to exercise reasonable care in operating the mower and damaged it.
- Conversion, because the neighbor took the mower from Nadia's shed and used it without permission.
- Private nuisance, because the neighbor interfered with Nadia's use of her property and caused her to incur repair costs.
- Trespass to chattels, because the neighbor intentionally used Nadia's mower and caused damage to it. (correct answer)
Explanation: When you see a claim involving interference with someone's personal property, you're in the realm of intentional torts—specifically, the difference between conversion and trespass to chattels. The key distinction is the severity of the interference. Conversion requires a serious, substantial deprivation—like destroying the item or keeping it permanently—while trespass to chattels covers lesser interferences that still cause damage or dispossession. Here, the neighbor intentionally took and used the mower without permission, and his use caused a specific, repairable harm (the frayed cord). That fits trespass to chattels perfectly: an intentional interference with your right to possess the chattel, resulting in actual damage.
The negligence claim fails because the neighbor's act was intentional, not careless—he deliberately used the mower. Conversion is too strong: he returned it, and the damage was minor, so the interference wasn't serious enough to justify a forced sale of the property. Private nuisance involves interference with the use and enjoyment of land, not personal property like a lawn mower, and the facts don't show an ongoing or substantial disturbance of your property interest.
Your takeaway: when a tort involves intentional use of someone else's chattel plus damage, ask how severe the interference was. If it's temporary and repairable, it's trespass to chattels; if it's essentially a "taking" that deprives the owner of the chattel's value, it's conversion. Watch for the word "intentional" to rule out negligence.
Question 2
State Oil operates a refinery that has for years released noxious fumes over the town of Eastbrook. Many residents, including Lena, suffer headaches and keep windows closed. Lena, a commercial beekeeper two miles downwind, has lost 15% of her hives and significant honey production because of the fumes. Lena sues State Oil for damages, alleging a public nuisance. Section 4 of the Model Public Nuisance Remedies Act provides: '(a) A public nuisance is an unreasonable interference with a right common to the general public. (b) A private person may maintain an action for damages for a public nuisance only if the person has suffered injury of a kind different in kind, not merely in degree, from the injury suffered by the general public. (c) An injury that results from the exercise of a right common to the general public, such as the right to breathe clean air, is not different in kind merely because it is more severe.'
Which of the following is Lena's best argument for satisfying the special-injury requirement?
- Her injury is to her commercial beekeeping property and livelihood, not merely to the air she breathes, so it is different in kind from the public's generalized harm. (correct answer)
- The fumes interfere with a right common to the general public, and the refinery's conduct is unreasonable.
- Her headaches are more frequent and severe than those of other residents, so her injury is greater in degree.
- The fumes have caused the death of her bees by physically invading her land, making the nuisance a trespass as well.
Explanation: Whenever you see a private action for public nuisance, your first step is to apply the special-injury rule: the plaintiff must show harm different in kind, not merely in degree, from the public's harm. The statute reinforces this by stating that suffering the same kind of harm—like breathing dirty air—more severely doesn't count. Lena's best argument is that her injury is to her commercial beekeeping property and livelihood, not merely to the air she breathes, so it is different in kind from the public's generalized harm. This works because her economic and property interest in the bees is distinct from the public's shared interest in clean air. The option about the fumes interfering with a right common to the general public and the refinery's conduct being unreasonable only proves the existence of a public nuisance, not Lena's special standing. The option about her headaches being more frequent and severe falls into the trap of Section 4(c): a greater degree of the same harm is insufficient. Finally, the option about the fumes physically invading her land and making the nuisance a trespass is a distraction—it might support a separate trespass claim, but it doesn't explain why her injury is different in kind from the public's for the public nuisance action. Remember: the special-injury requirement focuses on the nature of the harm, not its severity or the tort label you might attach.
Question 3
An original manuscript by a noted author is stolen from Mira's library. The thief sells it to Rook, a dealer, who does not know it is stolen. Rook spends $8,000 conserving the manuscript; his work increases its market value by $10,000. Mira later finds the manuscript in Rook's shop and demands its return. Rook refuses, asserting that he bought it in good faith and improved it. Mira sues Rook for conversion. The state's conversion statute provides:
§ 1. A person is liable for conversion if the person intentionally exercises dominion or control over a chattel that so seriously interferes with another's right to possession that the person must pay the chattel's full value. Good faith is not a defense.
§ 2. A good-faith purchaser for value of stolen goods acquires no title against the true owner. The owner may recover the goods, or their value, from the purchaser after an unqualified demand and refusal.
§ 3. Damages for conversion are measured by the chattel's fair market value at the time and place of conversion. If the defendant in good faith added value to the chattel and the plaintiff instead elects damages as of the time of judgment, the defendant is entitled to a credit equal to the lesser of (i) the defendant's cost in adding that value or (ii) the increase in the chattel's market value caused by the defendant's efforts. The plaintiff may elect the measure that yields the higher recovery.
At the time of Rook's refusal, the manuscript is worth $120,000. At trial, after a general rise in the market for the author's works, it is worth $160,000. What is the maximum amount of money damages Mira may recover in her conversion action?
- $120,000
- $150,000
- $152,000 (correct answer)
- $160,000
Explanation: Whenever a conversion statute offers alternative damage measures, don't just pick one—calculate both and apply any credits. Here, the "time of conversion" value is $120,000, so under the first measure Mira could recover $120,000. But she may instead elect damages as of the time of judgment: $160,000. Because Rook added value in good faith, he receives a credit equal to the lesser of his $8,000 cost or the $10,000 market-value increase he caused; that lesser amount is $8,000. Thus the judgment-date recovery is $160,000 − $8,000 = $152,000. Since that exceeds $120,000, Mira maximizes recovery at $152,000.
The $120,000 choice reflects only the conversion-date measure and ignores the statute's election. The $160,000 choice ignores the good-faith improver’s credit and would give Mira the value of Rook’s improvements for free. The $150,000 choice subtracts $10,000—the increase in market value caused by Rook’s work—but the statute specifically uses the lesser of cost or increase, so the credit must be $8,000, not the full $10,000.
On exam day, when a damages provision lets the plaintiff elect, compute both paths and remember to subtract the lesser credit, not the larger improvement value.
Question 4
A nightclub opened next to a family home. Every night until 2 a.m., the club plays loud music and shines bright floodlights that wash over the family's yard and bedrooms. The family has suffered no physical damage to the property, but they can no longer use their backyard in the evening or sleep with the windows open. They sued the nightclub.
Which claim most likely supports the family's request for an injunction?
- Public nuisance, because the nightclub's operation disturbs the peace and quiet of the entire neighborhood and harms public comfort.
- Trespass to land, because the sound waves and light physically enter the family's property without permission and disrupt their sleep.
- Private nuisance, because the noise and light substantially and unreasonably interfere with the family's use and enjoyment of their land. (correct answer)
- Negligence, because the nightclub failed to take reasonable steps to minimize the disruption to neighboring residents.
Explanation: When you see a claim for an injunction based on noise, light, or other interference with property, your first instinct should be to sort between nuisance and trespass. Nuisance protects the use and enjoyment of land; trespass protects exclusive possession against physical invasion. Here, the family's complaint is that they can't use their backyard or sleep with windows open—classic loss of enjoyment, not a physical occupation of the land.
The private nuisance claim wins because the nightclub's loud music and bright floodlights are substantial, unreasonable interferences with the family's use and enjoyment of their property. They are ongoing, nightly, and deprive the family of ordinary uses (outdoor evening time, open windows). No physical damage is required—nuisance covers discomfort and inconvenience.
Why not the others? Public nuisance fails because the harm is to a specific family, not to the general public's rights (like a blocked road). Trespass to land fails because sound and light are intangible and do not physically enter the land in a way that displaces possession—nuisance is the correct theory for intangible invasions. Negligence fails because the family isn't suing for damages caused by unreasonable carelessness; the claim is about the ongoing interference itself, which is strict liability under nuisance, not about a breach of a duty of care.
Strategy: When a question involves "can't enjoy my property" due to noise/light/odor, always choose private nuisance unless the interference affects the public at large. Remember: trespass = physical invasion; nuisance = interference with enjoyment.
Question 5
An energy company drilled a well on its own land and then angled the well underground so that it passed beneath a neighboring ranch. The well has been pumping oil from beneath the ranch for six months. The company never enters the surface of the ranch. The rancher sued to stop the pumping and to recover for the oil already removed.
Which legal issue is most likely to determine whether the rancher can obtain an order stopping the pumping?
- Whether the company's angled well beneath the ranch is a trespass to the rancher's land. (correct answer)
- Whether the oil removed from beneath the ranch became the company's property once it was pumped.
- Whether the pumping substantially interferes with the rancher's use and enjoyment of the surface of the ranch.
- Whether the company failed to exercise reasonable care in locating the well before drilling began.
Explanation: Whenever you see an angled-well or subsurface-invasion fact pattern, think property law and the difference between trespass and nuisance. A trespass is any intentional physical invasion of another's land—including the subsurface. Here, the company's wellbore passes directly beneath the ranch, so it has invaded the rancher's property even though it never enters the surface. That ongoing physical invasion is the key to an injunction: courts will stop a continuing trespass, not merely award damages.
The correct issue is whether the angled well beneath the ranch is a trespass to the rancher's land. It is, and that supports both stopping the pumping and addressing the removed oil.
The other choices are traps. Whether the oil became the company's property once pumped implicates the capture rule, but it does not answer whether the ongoing trespass can be enjoined. Whether the pumping substantially interferes with the surface use describes nuisance, but the rancher does not need to show surface interference when the invasion is physical and subsurface. Whether the company failed to exercise reasonable care in locating the well is negligence language; trespass liability does not require carelessness—intentionally drilling under another's land is enough.
Study tip: on the bar exam, if a fact pattern involves a physical invasion of land, including below the surface, classify it as trespass first. Save nuisance analysis for cases involving odors, noise, or other interference with use and enjoyment.
Question 6
Victor owns a large estate. Maya, a private investigator, was hired by Victor's neighbor to document the layout of Victor's landscaping and the location of his security cameras. Over a two-hour period, Maya flew a drone across Victor's estate 12 times at 250 feet. Victor had previously sent Maya a cease-and-desist letter asking her not to fly over his land. The flights were not audible or visible from the ground and did not disturb Victor's use of the estate. Victor sues Maya for trespass. Section 3 of the Model Airspace and Land Use Act provides: '(a) A person is liable for trespass to land if the person enters land or causes an object to enter land, except that an entry into the airspace above land is not a trespass if it occurs at an altitude and in a manner that is reasonable and does not interfere with the possessor's use and enjoyment of the land. (b) An entry into the airspace is unreasonable if it is made at a very low altitude, if it is persistent or intrusive, or if it is made for the purpose of conducting surveillance that the possessor has expressly asked to stop. (c) This section does not affect liability for nuisance, privacy, or other torts.'
Is Maya liable for trespass?
- Yes, because Maya made repeated flights over Victor's land for the purpose of surveillance after he expressly asked her to stop, making the airspace entry unreasonable. (correct answer)
- No, because the drone was in navigable airspace and never touched the land or anything attached to it.
- No, because 250 feet is not a very low altitude and the flights did not interfere with Victor's use and enjoyment of the estate.
- Yes, because any intentional flight over another person's land is a trespass regardless of altitude.
Explanation: Whenever a torts question provides a statute, the statute controls over general common law. This question tests the modern rule on airspace trespass, where an entry is only a trespass if it is unreasonable. Maya is liable because her actions fall squarely within the statute's definition of unreasonable. Section 3(b) states an entry is unreasonable if it is persistent or if it is made for surveillance that the possessor expressly asked to stop. Maya flew 12 times in two hours (persistent) for the purpose of documenting the layout (surveillance) after Victor sent a cease-and-desist letter (expressly asked to stop). Thus, the exception in (a) does not apply. Now consider the distractors. The choice claiming there is no liability because the drone was in navigable airspace and never touched the land misapplies the law—the statute explicitly covers objects entering the airspace, not just physical contact with the soil. The choice claiming no liability because 250 feet is not low and didn't interfere with use misreads the statute; while (a) mentions altitude and interference, (b) independently creates unreasonableness for persistence or surveillance after a request to stop. Finally, the choice stating any intentional flight is a trespass reflects the outdated common law, but the statute creates a reasonableness exception, so that absolute rule is wrong. Strategy tip: When you see a statute, look for specific factual triggers that activate it—like "repeated" or "asked to stop"—they often signal the correct answer.
Question 7
During a fast-moving wildfire, the city fire chief ordered a firebreak to be bulldozed through a private ranch. The firebreak destroyed a fence and several trees on the ranch but helped stop the fire from reaching a nearby town. The ranch owner sued the city for the damage.
Which defense should the city most likely assert?
- Private necessity, because the fire chief acted to prevent harm to the town rather than for personal benefit.
- Public necessity, because the fire chief reasonably acted to protect the community from a serious public harm. (correct answer)
- Sovereign immunity, because the city cannot be sued for the discretionary acts of its fire department.
- Consent, because the ranch owner presumably would have consented to measures needed to protect the town.
Explanation: Whenever you see a government official damaging private property to avert an emergency, think about the tort defense of necessity — and crucially whether the threatened harm is to the public or just to one person. That distinction separates public necessity from private necessity.
Here, the fire chief ordered a firebreak bulldozed through private ranch to stop a wildfire from destroying a nearby town. That is a classic public necessity defense: theief acted reasonably to prevent serious, imminent harm to the entire community. When public necessity applies, the government isnot liable for the property damage, even if the owner suffers loss. The town's safety outweighed the ranch owner's property interest under these circumstances.
Private necessity is wrong because it applies when someone damages property to save the actor's own life or property—not to protect the community. It is also only a partial privilege:he actor must pay for actual damage caused. Sovereign immunity is an overbroad distractor: government entities can be sued for torts, though some discretionary acts may be protected; here public necessity is the far more specific and complete defense. Consent fails because the fire chief never obtained—and could not reasonably wait for—the owner's agreement. Public necessity does not depend on presumed consent; it operates by law because the public harm was imminent.
On the bar exam, when property is intentionally damaged in an emergency, first ask: Who was threatened—the public or only an individual? If the public, public necessity is an absolute defense; if only a private interest, private necessity still leaves liability for damages. That one distinction often determines the answer.
Question 8
A developer built a low bridge across a navigable river that blocks all motorboats from passing upstream. The river had long been open to the public for boating and fishing. A fishing lodge located upstream, whose guests normally arrived by boat, lost most of its business. The lodge owner sued the developer.
Which legal theory is the most likely basis for the lodge owner's claim?
- Private nuisance, because the bridge interferes with the lodge owner's use and enjoyment of his land and reduces its value.
- Public nuisance, because the bridge interferes with a public right of navigation and the lodge owner suffered a distinct harm. (correct answer)
- Trespass to land, because the bridge blocks access to the water adjoining the lodge owner's property and violates riparian rights.
- Interference with contractual relations, because the bridge caused the lodge owner's guests to cancel and reduced his expected income.
Explanation: Whenever you see a claim involving a waterway, the first question is whether the harm is to a public right or to the landowner's private use. Here, the river was open to the public for boating, and the bridge blocked motorboats from passing upstream. That is an interference with the public right of navigation. But a public nuisance normally supports a government prosecution or a suit by someone who suffers a harm different in kind from the public. The lodge owner lost guests who arrived by boat—this is a distinct, particular injury beyond the general inconvenience to other boaters. That makes public nuisance because the bridge interferes with a public right of navigation and the lodge owner suffered a distinct harm the strongest claim.
The private nuisance theory falls short because the bridge does not directly interfere with the lodge owner's use and enjoyment of his land; it interferes with the public waterway, and his lost business is an economic consequence. Trespass to land is also wrong: trespass requires an invasion of the land itself, and the bridge is not on his property; riparian rights do not guarantee unobstructed navigation. Interference with contractual relations fails because there was no contract with the guests—they simply stopped booking, which is not the tort of inducing a breach.
Your takeaway: when injury flows from blockage of a public resource, check for public nuisance first, then ask whether your client has suffered a special harm distinct from the public's.
Question 9
Tomas has operated a wood-fired pizza oven in his backyard for eight years. Priya bought the neighboring house three years ago and last year began growing rare orchids in a greenhouse. The orchids are unusually sensitive to smoke particulates. On windy days, smoke from the oven drifts onto Priya's property. The smoke is barely noticeable to ordinary residents, and Tomas uses the best available filters. The smoke has caused $15,000 in losses to Priya's orchid business. Priya sues Tomas for private nuisance. The court in Nishi v. Fairweather held: 'A private nuisance is a substantial and unreasonable interference with another's use and enjoyment of land. The interference is unreasonable only if a person of ordinary sensibilities would be substantially annoyed or harmed by the same condition. A plaintiff whose use is abnormally sensitive may not recover unless the defendant's conduct would also interfere with an ordinary use of the land. The plaintiff's coming to the nuisance is relevant to whether the interference is unreasonable, but it is not a complete defense.'
Which of the following is the best basis for a decision in Tomas's favor?
- Tomas's pizza oven was in operation before Priya bought her house, and Priya came to the nuisance.
- The smoke would not substantially interfere with an ordinary residential use of Priya's land, and her orchids are an abnormally sensitive use. (correct answer)
- Tomas's use of best available filters shows that he was not negligent and that the interference was not intentional.
- The smoke does not physically invade Priya's land, and a private nuisance requires a physical invasion.
Explanation: Whenever you see a private nuisance question, start with the core standard: a substantial and unreasonable interference with another's use and enjoyment of land. The court's own rule adds a crucial limitation—the interference is judged against ordinary sensibilities, and an abnormally sensitive plaintiff cannot recover unless the defendant's conduct would also harm an ordinary use.
Here, Tomas's smoke is barely noticeable to ordinary people, and he uses the best available filters. Priya's rare orchids are an unusually sensitive use. Because the same smoke would not substantially interfere with an ordinary residential backyard or home, Tomas wins. The $15,000 in losses to her specialty business does not convert an otherwise ordinary condition into an unreasonable nuisance.
The choice that Tomas's oven predated Priya's greenhouse is tempting, but the passage tells you coming to the nuisance is only relevant, not a complete defense. The choice that Tomas's filters prove non-negligence misses the point: nuisance liability can exist without negligence if the interference is intentional and unreasonable, though here it is not unreasonable. The choice that smoke is not a physical invasion is also wrong—private nuisance can arise from nontrespassory invasions like smoke, odors, or noise; it does not require a physical trespass.
Study tip: when a nuisance plaintiff has an unusually sensitive use, ask first whether the defendant's activity would bother an ordinary person. If not, the abnormal-sensitivity plaintiff loses regardless of actual harm.
Question 10
Dana owns a tree-care company. Pete owns a farm. On March 1, Pete gave Dana oral permission to enter the farm, inspect an oak tree, and attach a sensor that would remain for one month. On March 2, Pete e-mailed Dana: 'Remove the sensor immediately and do not set foot on my property again.' Dana did not remove the sensor until March 15 and did not physically enter the property after March 2. Dana believed in good faith that the e-mail could not revoke the one-month permission for the sensor, but that belief was mistaken. Section 3 of the Model Land Trespass Act provides: '(a) A person is liable for trespass to land if the person intentionally enters or remains on land in the possession of another after the possessor has withdrawn permission. (b) A person is liable for trespass if the person intentionally causes a thing to enter or remain on land in the possession of another after permission for that thing has been withdrawn. (c) Mistake as to the existence or scope of permission is not a defense. (d) A separate trespass occurs on each day after a reasonable time for removal has elapsed that a thing remains in violation of subsection (b).'
Is Dana liable for trespass to Pete's land?
- No, because Dana did not physically re-enter the property after Pete withdrew permission, and a trespass requires a personal entry.
- No, because Pete's one-month permission for the sensor was a grant of a property interest, so Pete could not revoke it before March 15.
- Yes, but only for the original March 1 entry, because the sensor's continued presence is not a separate trespass and the March 1 entry was not privileged.
- Yes, because Dana intentionally caused the sensor to remain after Pete withdrew permission, mistake is not a defense, and each day's continued presence is a separate trespass. (correct answer)
Explanation: Whenever you see a trespass question involving a statute, read the statutory definitions carefully — the act may expand liability beyond physically walking onto land. Here, the key is that trespass can occur either by personal entry or by causing a thing to enter or remain.
Dana is liable because Pete withdrew permission on March 2, and Dana intentionally caused the sensor to remain on the property after that withdrawal. Under subsection (b), causing a thing to remain after permission is withdrawn is trespass. Subsection (c) eliminates Dana's good-faith mistake as a defense, so her belief that the e-mail could not revoke the one-month permission does not help. Finally, subsection (d) makes each day after a reasonable removal time a separate trespass, which is why liability extends beyond March 2.
The choice saying "No, because Dana did not physically re-enter" misunderstands the statute: physical re-entry is not required when a thing remains. The choice saying the one-month permission was a property interest is also wrong; Pete gave only oral permission, which was revocable, and even if Dana thought it was irrevocable, mistake is not a defense under subsection (c). The choice limiting liability to the original March 1 entry fails because that entry was privileged — Dana had permission at the time — and the continuing presence of the sensor triggers a new violation under subsection (b).
For similar questions, remember: permission can be revoked, good-faith mistakes are not defenses, and "remaining" can be as actionable as entering.
Question 11
Morgan, a backcountry skier, checked an avalanche forecast that warned of considerable danger and skied anyway. A small avalanche occurred, and Morgan fled on foot to avoid the storm, broke into a locked ranger cabin, damaged the door, and consumed $80 of food. The ranger sues Morgan for trespass and damages. Section 6 of the Model Emergency Entry Act provides: '(a) A person is privileged to enter or remain on land in the possession of another if the entry or remaining is reasonably necessary to avoid serious harm to the person, the person's land, or the person's chattels. (b) The privilege under subsection (a) applies even if the necessity arose from the actor's own negligence or mistake, but does not apply if the actor intentionally created the necessity or if the harm threatened was less serious than the invasion. (c) A person who enters under subsection (a) is liable for any actual harm caused to the land or chattels of the possessor.'
Which of the following best describes Morgan's liability to the ranger?
- Morgan is liable for trespass because the risk was foreseeable and Morgan's decision to ski was intentional, so the necessity was self-created.
- Morgan is not liable for any harm because the entry was reasonably necessary to avoid serious injury or death.
- Morgan is liable for trespass but not for the door or food because the privilege protects only personal safety, not property damage.
- Morgan is not liable for trespass, but is liable for the damaged door and the $80 of food as actual harm caused by the privileged entry. (correct answer)
Explanation: Whenever you see a statutory privileges question, parse it in stages: first decide whether the entry privilege exists, then decide what liability remains. Morgan's entry qualifies under Section 6(a): fleeing an avalanche to avoid serious injury or death is reasonably necessary to avoid serious harm. Section 6(b) is crucial—the privilege applies even if the necessity arose from Morgan's own negligence or mistake, but not if Morgan intentionally created the necessity. Morgan intentionally skied despite the forecast, but that is negligent risk-taking, not intentionally creating the avalanche emergency. So Morgan is not liable for trespass. However, Section 6(c) explicitly says a privileged entrant is liable for any actual harm caused to the possessor's land or chattels. The damaged door and the $80 of food are exactly that kind of harm, so Morgan must pay for them.
The "liable for trespass because the risk was foreseeable" choice wrongly equates an intentional ski with intentionally creating the necessity—the statute would deny privilege only if Morgan deliberately caused the emergency. The "not liable for any harm" choice ignores subsection (c). And the "liable for trespass but not for door or food" choice flips the rule: the privilege excuses the trespass itself, not the property damage caused during the privileged entry.
On the exam, apply statutes subsection by subsection—privilege first, damages second—and watch for a "liable for actual harm" clause that imposes damages even on a privileged entrant.
Question 12
While moving a sculptor's bronze work, a mover decided the sculpture would look better painted bright green. Without asking, he spray-painted the sculpture. The paint cannot be removed without damaging the surface, and the sculpture's value as an artwork has fallen dramatically. The sculptor sued the mover.
Which legal theory best supports the sculptor's claim for the full value of the sculpture?
- Negligence, because the mover acted carelessly in applying paint to the sculpture and failed to protect it.
- Trespass to chattels, because the mover physically touched the sculpture without permission and altered its appearance.
- Conversion, because the mover intentionally and permanently altered the sculpture in a way that destroyed its value. (correct answer)
- Breach of bailment, because the mover had custody of the sculpture and returned it damaged without authorization.
Explanation: When a torts question involves property damage, first classify the defendant's state of mind (intent vs. negligence) and the severity of the interference. Here, the mover intentionally spray-painted the sculpture, so negligence is immediately out. The key distinction is between trespass to chattels and conversion. Conversion requires an intentional act so serious that it deprives the owner of the chattel's full value. Here, the paint is permanent and cannot be removed without damaging the surface, and the sculpture's value has fallen dramatically. This complete destruction of its economic worth constitutes a serious interference, allowing the sculptor to recover the full value. Therefore, conversion is the best fit. The negligence choice fails because the mover acted deliberately, not carelessly. The trespass to chattels choice is a trap: trespass covers minor interferences where damages are repair costs or loss of use, but the permanent destruction here elevates the wrong to conversion. The breach of bailment choice also fails—while a mover has custody, bailment requires a specific transfer for a limited purpose, and intentional torts are not covered by bailment's implied obligations. As a study tip, watch for trigger words like "permanent," "destroyed," or "value fallen dramatically"—these signal conversion, while "temporary" or "minor damage" signals trespass to chattels. Always ask: was the owner completely deprived of the item's value?
