- Which issue is most likely to determine whether the company is liable to the patient?
Answer: Whether the warning given to the physician adequately alerted the physician to the need for blood monitoring.
Whenever you see a prescription-drug failure-to-warn question, think of the learned intermediary doctrine: the manufacturer's duty runs to the physician, not directly to the patient. So the key question is whether the warning the company gave the physician was adequate.
Here, the company did warn physicians that the drug could cause aplastic anemia and instructed weekly blood tests. The physician read the label but chose not to order tests because she thought the risk did not justify the cost. The company's liability therefore turns on whether that label warning adequately alerted the physician to the need for blood monitoring. If the warning was sufficient, the company fulfilled its duty; if it was not—say, if it understated the risk or buried the monitoring instruction—the company could be liable.
The distractor about whether the patient would have read a direct warning misses the point: under the learned intermediary doctrine, the manufacturer is not required to warn the patient directly, so the patient's hypothetical reading is not the decisive issue. The physician's cost-based decision not to order blood tests is about the physician's own medical judgment, not the adequacy of the company's warning. And whether the manufacturer knew this particular patient had epilepsy is irrelevant; the duty is to warn physicians generally about known risks of the drug, not to individualize warnings.
On the exam, when you see a drug warning question, immediately ask: Was the warning to the physician adequate? Then watch for answer choices that shift blame to the doctor or demand patient-directed warnings.
- Which fact, if true, would most weaken the manufacturer's defense that it reasonably relied on the plating company to warn its employees?
Answer: The manufacturer knew that the plating company's owner had previously failed to pass on safety information to employees.
This question tests the duty to warn in products liability, specifically the "sophisticated intermediary" doctrine. When a manufacturer sells a dangerous product to an employer, it can satisfy its duty to warn by providing the warning to the employer, relying on the employer to pass it on to employees. That reliance, however, is only reasonable if the manufacturer has no reason to doubt the intermediary's reliability.
Here, the fact that the manufacturer knew the plating company's owner had previously failed to pass on safety information directly destroys that reasonableness. If the manufacturer knows the employer is an unreliable conduit for warnings, it cannot simply hand over a safety data sheet and claim it fulfilled its duty to the plater. This knowledge shifts the duty back to the manufacturer to warn the ultimate users directly or take other precautions.
Now, the wrong choices. The fact that the plater had not received any training about solvents shows the employer's negligence, but it does not attack the reasonableness of the manufacturer's reliance unless the manufacturer knew about that training gap — so it's insufficient. The solvent being delivered in unlabeled drums is a separate potential warning defect, but it does not address the specific defense of relying on the employer to warn employees. Finally, the plater continuing to work after experiencing breathing problems suggests comparative negligence or assumption of risk on the plater's part, which would actually strengthen the manufacturer's defense, not weaken it.
For your study, remember: the sophisticated intermediary defense fails when the manufacturer knows or should know that the intermediary is unreliable. On exam day, look for facts establishing the manufacturer's actual knowledge of the intermediary's track record.
- Which fact, if true, is most important in allowing the contractor's tort claims to proceed?
Answer: The crane's collapse damaged the contractor's forklift, which was property other than the crane itself.
Whenever you see a defective product case, ask first: did the defect injure only the product itself, or did it also damage people or other property? In tort, a manufacturer can be liable for harm caused by its defective product—but the cost of repairing or replacing the defective product itself is an economic loss that belongs in contract, not negligence or strict liability.
. The critical fact here is that the crane's collapse damaged the contractor's forklift, which was property other than the crane itself. That "other property" damage creates the kind of harm tort law protects, so it allows the negligence and strict liability claims to proceed—at least for the forklift and consequential damages, even though the crane's own repair cost remains largely a contract remedy.
The other facts do not overcome this threshold. A defective weld caused by the manufacturer's failure to follow its own welding specifications tends to prove breach of duty, but no amount of fault can save a tort claim if the only loss is to the defective product itself. Not having paid the full purchase price might affect contract remedies or title, but it has no bearing on whether tort duties apply. Advertising the crane as safe for heavy lifting could support a warranty or misrepresentation argument, but it cannot manufacture tort liability where only economic loss to the product itself exists. The lesson: in products liability questions, isolate the injury. Damage to "other property" or people opens the tort door; damage only to the product itself keeps the case in contract.
- Under the Act, which party is entitled to judgment?
Answer: The manufacturer, because Baxter did not prove that the loosened connection existed when the heater left the manufacturer's control and did not eliminate ordinary wear as a reasonable cause.
This question tests manufacturing-defect liability under Columbia's Products Liability Act. The key is burden allocation: the plaintiff must prove the product was defective when it left the defendant's control, though that proof may be direct or circumstantial. Circumstantial proof can work by showing the product malfunctioned during normal use and that other reasonable causes were eliminated.
Here, Baxter showed the heater malfunctioned and both experts agreed a loosened connection could cause a fire. But his own expert could not say whether the connection was loose at the factory or loosened through ordinary vibration. The manufacturer's expert said ordinary use could explain it, and Baxter offered no evidence eliminating that reasonable cause. Since ordinary vibration during normal use is exactly the kind of alternative explanation the Act requires a plaintiff to rule out, Baxter did not carry his burden. Therefore judgment goes to the manufacturer.
The answer choice saying "Baxter, because the heater malfunctioned and the manufacturer did not prove post-sale alteration" misses the point: the absence of alteration only defeats an affirmative defense; it does not prove the defect existed when the product left the manufacturer's control. The choice claiming the burden shifts to the manufacturer after a malfunction is also wrong—the Act keeps the burden on the plaintiff. Finally, the choice demanding direct evidence is wrong because the Act expressly allows circumstantial evidence; Baxter's problem is not that his evidence was circumstantial, but that it failed to eliminate ordinary wear.
On exam day, remember: "malfunction during normal use" is only half the test—eliminating other reasonable causes is the other half.
- Under Martinez, which is correct?
Answer: The manufacturer is not liable because Vera's removal of the guard was a substantial factor and the manufacturer's warning was conspicuous, specific, and adequate.
When a question presents a product-defect claim alongside a fact pattern of user modification, your first instinct should be to apply the affirmative defense of misuse or alteration. Under Martinez, the defense fails only if the misuse was reasonably foreseeable and the product lacked an adequate warning about that specific misuse. Here, the key is whether the warning satisfies Martinez's three-prong test.
The manufacturer prevails because the warning was adequate. It was conspicuous (bold type on the first page), it communicated the specific risk (death or injury from falling loads if the guard is removed), and it was reasonably calculated to reach the user—a manual delivered with the forklift is a standard channel. Because the warning is adequate, the product is not defective for failing to warn, even though the removal was foreseeable. Vera's removal was a substantial factor in her injury, so the affirmative defense applies, and the manufacturer is not liable.
The choice claiming the manufacturer is liable because a feasible special-tool design would have prevented the harm misreads Martinez: a feasible alternative design is irrelevant when the warning is adequate, because the defect alleged (lack of adequate warning) is cured. The choice saying liability follows because the warning was only in the manual, not on the guard, is too strict—Martinez does not mandate on-product labels; it requires that the warning be reasonably calculated to reach the user, which a manual satisfies. Finally, the choice asserting the removal was an unforeseeable misuse is factually wrong—the manufacturer knew purchasers removed guards, making it foreseeable.
Study tip: For misuse defenses, always evaluate the warning's adequacy before discussing foreseeability. If the warning is adequate, the defense stands regardless of foreseeability. If not, the defense collapses.
- Under the Act, what may Delia recover from Pumps Inc.?
Answer: Nothing, because the boat was the product sold to Delia and the fuel pump, engine, and hull were all component parts of that product.
When you see a strict product liability question, the first step is to identify the exact "product" sold. Here, the Act defines "product" as the tangible personal property sold to the plaintiff, including all component parts integrated into it. Since Delia bought the motorboat, the boat is the product; the fuel pump, engine, and hull are all component parts of that boat.
The Act defines "harm" as physical injury or damage to property other than the product itself. It explicitly excludes damage to the product itself, including damage caused by one component part to another component part of the same product. The defective impeller in the fuel pump destroyed the engine and punctured the hull—both are components of the same boat. Thus, all damage is to the product itself, not "other property." No physical injury occurred, so Delia recovers nothing in tort.
The option claiming recovery for the boat hull only is wrong because the hull is a component part, not other property, and the engine damage is also excluded. The option claiming recovery for the engine and hull is wrong for the same reason—both are parts of the product, and component-to-component damage is barred. The option claiming recovery for the engine only is wrong because the engine is a component part; its damage is to the product itself, even though it wasn't the defective component.
Your study tip: whenever a statute defines "product" to include components, ask whether the damaged item is part of that same finished product. If yes, the economic loss rule bars tort recovery—you must look to contract or warranty law instead.
- Which fact is most important in determining whether the consumer's claim is for a manufacturing defect or a design defect?
Answer: The mold produces the same thin bottom even when production conditions are normal.
Whenever you see a products-liability question asking whether a flaw is a manufacturing defect or a design defect, focus on one idea: did the product depart from its intended design, or did it conform to an unsafe design? A manufacturing defect means something went wrong in making the particular item; a design defect meanstheimproperconditionis baked into the product itself.
Here, the thin bottom is the most telling fact because even under normal production conditions, the mold produces the same thin bottom. That evidence shows the bottom was not an accidental deviation from spec—it was part of the product's intended design. Therefore the claim sounds in design defect, not manufacturing defect.
The fact that the kiln overheated on the night in question sounds relevant, but it is not dispositiveifo the same bottom occurs consistently from other batches, then overheating did not cause the defect—the mold did. Likewise, other mugs from the same batch also having thin bottoms shows the problem affected multiple items, but a batch-wide manufacturing defect could also produce that pattern; it does not distinguish manufacturing from design. Finally, how the mug shattered—hot water versus a drop—relates to causation or the defect's dangerousness, not to whether the defect was manufacturing or design in origin. Remember: conformity to design points to design defect; nonconformity points to manufacturing defect.
- Under Diaz, which is correct?
Answer: The manufacturer is liable because no provider made an individualized medical judgment to administer Nordal to Rosa and the manufacturer did not warn the provider who actually administered the drug.
Whenever you see a failure-to-warn question, start with the learned intermediary doctrine: a manufacturer only needs to warn the prescribing physician. But Diaz creates a crucial carve-out—this protection exists only when a provider makes an individualized decision. Here, Dr. Chen wrote a standing protocol giving Nurse Patel zero discretion. Because no individualized medical judgment was made for Rosa, Dr. Chen was not the learned intermediary. The manufacturer warned Dr. Chen and the pharmacy, but not Nurse Patel, who actually administered the drug. That failure to warn the actual administrator is the breach, so the manufacturer is liable.
Now test the distractors. The choice saying the manufacturer is not liable because it warned Dr. Chen, the physician who wrote the protocol, is the classic trap—*Diaz* explicitly rejects that a physician who drafts a protocol but doesn't see the patient is sufficient. The choice about the hospital pharmacy receiving the warning is also wrong; pharmacy staff are not the learned intermediary because they neither make an individualized decision nor administer the drug. Finally, the choice requiring Rosa to prove Dr. Chen would have changed the protocol misplaces causation—*Diaz* imposes a strict rule that the manufacturer must warn the actual administering provider when no individualized judgment is made, so the plaintiff need not show what the physician would have done.
Your takeaway: whenever you see a standing order or protocol, the manufacturer must warn the actual administerer, not just the physician who drafted the rule.
- Which fact is most important in determining whether the alteration defense will succeed?
Answer: Whether the manufacturer knew or should have known that some users removed the guard to make plunge cuts.
When you see a products liability question raising the substantial alteration defense, your immediate focus should be on foreseeability. A manufacturer is not liable for injuries caused by a user's modification if that modification was unforeseeable. The key fact here is whether the manufacturer knew or should have known that some users removed the guard to make plunge cuts. If that practice was reasonably foreseeable, the alteration defense fails, because the manufacturer had a duty to design a product that could withstand foreseeable misuse—even if the manual prohibited it.
The choice about whether the worker had read the warning in the manual addresses his own comparative negligence or assumption of risk, but that does not negate the manufacturer's liability for a foreseeable alteration. Similarly, whether the saw could be used for plunge cuts with the guard in place speaks to the product's overall utility or whether the design was defective, but it does not directly answer whether the removal itself was a foreseeable event. Finally, whether the worker's employer had instructed him to remove the guard might shift blame to the employer or raise issues of workplace negligence, but it still does not resolve the core issue of the manufacturer's knowledge of common user behavior.
For your study: whenever you see "substantial alteration" or "product misuse," immediately ask, "Was this alteration reasonably foreseeable?" That single question often decides the case, because a manufacturer must anticipate and guard against foreseeable alterations, even those contrary to warnings.
- Under the Act, which outcome is correct?
Answer: The manufacturer wins because the Section 2 presumption was not overcome: Marta needed clear and convincing evidence of both a feasible alternative design and a willful or wanton failure, and she did not.
This question tests how a state statute can impose a heightened burden of proof once a defendant shows compliance with industry standards. When you see a "state of the art" presumption in a products-liability statute, focus immediately on what the plaintiff must prove to overcome it and by what standard.
Here, the manufacturer proved the saw conformed to voluntary industry standards and that blade guards were not generally used, which triggers Section 2's rebuttable presumption that the product was not defective. Marta proved a feasible alternative design by a preponderance of the evidence, but that is only the normal Section 1(b) showing. Section 2 then raises the bar: the presumption may be overcome only by clear and convincing evidence of both a feasible alternative design and a willful or wanton failure to adopt it. Since the jury did not find willful or wanton conduct, the presumption stands, so the manufacturer wins.
The other choices each miss this structure. The claim that industry standards are "conclusive" is wrong because Section 2 makes them the basis for a rebuttable presumption, not an absolute shield. The argument that Marta wins merely by proving a feasible design by a preponderance ignores Section 2's heightened standard. And the consumer-expectation argument fails because Section 1(a) does not automatically control; Section 2 expressly applies to design-defect actions and a blade guard's absence does not necessarily defeat ordinary expectations.
Study tip: whenever a statute creates a rebuttable presumption, track the burden-shifting precisely — what triggers it, what rebuts it, and with what degree of proof.
- Which defense is the manufacturer most likely to assert successfully?
Answer: The government contractor defense, because the military approved reasonably precise specifications and the manufacturer conformed to them.
Whenever you see a product-defect claim against a manufacturer of military equipment, immediately think of the government contractor defense. That doctrine shields contractors when the military approved reasonably precise specifications, the equipment conformed to those specs, and the contractor warned the military of known dangers. Here all three elements are satisfied: the computer was built to detailed military-approved specifications, the manufacturer followed them exactly, and it informed the military of the potential failure mode while the military accepted the risk for cost reasons. That makes this defense the strongest one.
Federal preemption is too broad: military acceptance of equipment does not by itself displace state tort law; preemption requires an actual conflict with federal law or policy, which is what the government contractor defense specifically addresses. Assumption of risk fails because the pilot's general knowledge of military flying dangers is not the same as knowingly encountering this specific computer defect. Comparative fault is also not the best defense: the military's cost-driven acceptance might affect responsibility, but it does not eliminate the manufacturer's liability the way the government contractor defense does.
Remember: on the bar exam, "military equipment + government specs + warning to the military" is a trigger phrase for the government contractor defense. Separate that specific doctrine from general preemption and fault defenses.
- Under the Act, is Precision Machining liable to Ramon?
Answer: No, because the bracket was not defective and Precision did not substantially participate in the ladder's design.
When you see a component-part seller in a products liability question, your first move is to check the two exceptions to the general rule of no liability: was the component itself defective, or did the seller substantially participate in the finished product's design? Here, Precision made the bracket to LadderCo's exact specifications, and the bracket was not defective on its own—it met all specs and functioned as intended. The harm came from the ladder's design, which placed excessive stress on the bracket. Because Precision merely manufactured a non-defective component to the finished-product manufacturer's specs, that does not constitute substantial participation. The Act explicitly says manufacturing to specifications is not enough. So Precision is not liable. The choice that says "No, because the bracket was not defective and Precision did not substantially participate in the ladder's design" correctly captures both elements. The answer claiming "Yes, because Precision manufactured a component part and the component failed" ignores the key exceptions—a component can fail due to the finished product's design without the component itself being defective. The answer saying "Yes, because Precision manufactured the bracket to LadderCo's specifications and therefore is a manufacturer of the finished ladder" confuses making a part with designing the whole product; the Act defines a manufacturer as one who designs or produces a product or component, but that doesn't make Precision the ladder's manufacturer for liability purposes. Finally, "No, because only the seller of the finished product to Ramon can be liable" is too broad—component sellers can be liable under the exceptions, but here they aren't, so the reason is wrong. Study tip: On component-part questions, always ask two questions: (1) Was the component itself defective? (2) Did the seller participate in the finished product's design beyond following specs? If both are no, no liability.
