Troja v. Black & Decker Manufacturing Co.--62 Md. App. 101, 488 A.2d 516 (1985)
Facts: On January 10, 1979, Michael Troja accidentally amputated his thumb while operating a radial arm saw manufactured by Black & Decker. Troja sued Black & Decker for negligence and strict liability, but the negligence claim was withdrawn before trial. The strict liability claim was based on two theories:
A design defect due to the absence of a safeguard that would prevent the saw from operating without the guide fence.
A failure to warn about the dangers of using the saw without the guide fence.
The court granted a directed verdict for Black & Decker on the design defect claim due to insufficient evidence of the feasibility of a safer design in 1976. The jury found the saw unreasonably dangerous due to inadequate warnings but concluded Black & Decker was unaware of the defect when the saw was marketed. The court ruled in favor of Black & Decker. Troja appealed, arguing several errors, including the exclusion of expert testimony on the feasibility of a safer design and the refusal to admit evidence of post-1976 warnings.
Issue: whether Black and Decker is responsible for the plaintiff's injury due to the claimed design defects and failure to provide adequate warnings
Rule:
Strict Liability in Design Defects - Under Phipps v. General Motors Corp. and Restatement (Second) of Torts, § 402A, a seller is liable for physical harm caused by a product sold in a defective condition unreasonably dangerous to the user. Courts must weigh the utility of the design against the risk it poses. To prove a design defect, the plaintiff must show:
1.The technological feasibility of a safer alternative design at the time of manufacture.
2.The availability of materials required.
3.The cost of production and the product’s price to the consumer.
4.The likelihood of consumer acceptance of the safer design.
Strict Liability in Failure to Warn - A manufacturer must provide adequate warnings if the product presents risks that are not obvious to the user. Failure to do so can render the product unreasonably dangerous.
Application:
Design Defects
-Claim: Troja claimed the saw was defectively designed because it lacked a safeguarding system that would prevent operation without the guide fence in place.
-Evidence Requirement: To prove a design defect, evidence of the feasibility of a safer alternative design at the time of manufacture is necessary. This includes technological feasibility, cost of production, and consumer acceptance.
-Expert Testimony: Troja's expert, Gerald Rennell, lacked the necessary foundational knowledge and did not provide concrete evidence to support the feasibility and economic viability of incorporating an interlock safety feature in 1976. His assertions were speculative and unsupported by tests or detailed analysis.
-Court's Decision: The trial court excluded Rennell's testimony due to insufficient foundation and granted a directed verdict in favor of Black and Decker on the design defect issue. The court found no legally sufficient evidence of a feasible safer design, aligning with the precedent set by Singleton v. International Harvester Co.
Failure to Warn:
-Claim: Troja contended that Black and Decker failed to provide adequate warnings about the risks of using the saw without the guide fence, making it unreasonably dangerous.
-Expert Testimony: Dr. Robert Cunitz testified that the warnings provided were inadequate and that a specific warning about the dangers of using the saw without the guide fence should have been included. However, he acknowledged that the warnings conformed to 1976 federal and industry standards.
-Subsequent Warnings: Troja argued for the admission of evidence regarding stronger warnings placed on later models of the saw. The court excluded this evidence based on Federal Rule of Evidence 407, which bars evidence of subsequent remedial measures to prove culpable conduct, as it could confuse the jury regarding the product's defectiveness at the time of manufacture.
-Court's Decision: The jury found that the absence of specific warnings caused the saw to be defective and unreasonably dangerous, but concluded that Black and Decker did not know of the defect at the time it was marketed. The trial court's exclusion of subsequent warning evidence was upheld, following the rationale in Werner v. Upjohn, which discourages penalizing manufacturers for making improvements.
Conclusion: Black and Decker was not found responsible for Troja's injury due to design defects because Troja failed to provide legally sufficient evidence of a feasible safer design. Additionally, although the warnings were deemed inadequate, the jury concluded that Black and Decker did not have knowledge of the defect at the time of marketing, and the exclusion of subsequent warning evidence was deemed appropriate. Thus, the court affirmed the judgment in favor of Black and Decker.
Feedback & Notes:
Parallel Discussion of Murray v. Fairbanks Morse and Troja v. Black & Decker Manufacturing Co. Similarities
1.Nature of the Lawsuits:
-Both Cases: Both lawsuits involve personal injury claims grounded in strict products liability. The plaintiffs in each case alleged that their injuries were caused by defective products manufactured by the defendants.
2.Types of Defects Alleged:
-Design Defect: Both Murray and Troja claimed that the products were defectively designed, making them unreasonably dangerous.
-Failure to Warn: Both plaintiffs also argued that the manufacturers failed to provide adequate warnings about the dangers associated with the use of the products.
3.Strict Liability Doctrine:
-Both Cases: The courts applied the principles of strict liability, focusing on whether the products were sold in a defective condition that was unreasonably dangerous to the user, as outlined in the Restatement (Second) of Torts, § 402A.
4.Expert Testimony:
-Both Cases: Expert testimony played a crucial role in attempting to establish the existence of a defect and the adequacy of warnings provided by the manufacturers.
Differences
1.Facts of the Cases:
-Murray: Norwilton Murray was injured while installing an electrical control panel with a tack-welded cross-member that failed, causing him to fall.
-Troja: Michael Troja amputated his thumb while operating a radial arm saw that lacked a safeguard to prevent operation without the guide fence.
2.Outcome on Design Defect Claims:
-Murray: The jury found in favor of Murray on the design defect claim, determining that the product was defectively designed. The court adjusted the verdict based on Murray's contributory negligence.
-Troja: The court directed a verdict in favor of Black & Decker on the design defect claim, ruling that Troja failed to provide sufficient evidence on the feasibility of a safer alternative design.
3.Outcome on Failure to Warn Claims:
-Murray: The jury found that the warnings provided were inadequate, supporting the strict liability claim against Beloit.
-Troja: The jury found the warnings inadequate but concluded Black & Decker was unaware of the defect at the time of marketing, leading to a verdict in favor of Black & Decker.
4.Handling of Expert Testimony:
-Murray: The expert testimony supported the plaintiff’s claims regarding the design defect and inadequate warnings, contributing to the jury's favorable verdict.
-Troja: The court excluded the expert's testimony on the feasibility of a safer design due to a lack of foundational support, which weakened Troja’s design defect claim.
5.Subsequent Remedial Measures:
-Murray: The issue of subsequent remedial measures was not a central focus.
-Troja: The court excluded evidence of subsequent warnings (post-1976) on later models, aligning with the policy to encourage safety improvements without fear of liability for prior versions.
6.Impact of Plaintiff’s Actions:
-Murray: Murray was found 5% at fault, which slightly reduced his compensation but did not bar recovery.
-Troja: Troja’s actions were not a focal point in reducing liability, as the case focused more on the feasibility of a safer design and the adequacy of warnings.
Conclusion
The Murray v. Fairbanks Morse case resulted in a partial victory for the plaintiff due to successful arguments on design defect and failure to warn, supported by expert testimony and evidence of inadequate warnings. In contrast, the Troja v. Black & Decker Manufacturing Co. case saw the defendant prevail on the design defect claim due to the exclusion of critical expert testimony and the jury's conclusion that the manufacturer was unaware of the defect at the time of marketing. These cases illustrate the critical importance of providing sufficient evidence and expert testimony to support claims of design defects and the complexities involved in proving failure to warn under strict liability.
Is there a possibility to impose liability on the manufacturer based on design defect?
In product liability law, a manufacturer can be held liable for a design defect if the product is inherently dangerous due to its design, making it unreasonably dangerous for its intended use. The key elements to establish a design defect include:
Proof of Defect: Demonstrating that the design itself is flawed.
Feasibility of Alternative Design: Showing that a safer, economically feasible alternative design was available at the time of manufacture.
Risk-Utility Balance: Establishing that the risks posed by the design outweigh its utility.
Manufacturing defect v. design defect requirements
Manufacturing Defect
A manufacturing defect occurs when a product departs from its intended design, even though all possible care was exercised in the preparation and marketing of the product. Essentially, the product is flawed because it was not manufactured as designed. Here are the key requirements:
Deviation from Design: The product deviates from the manufacturer's design or specifications.
Existence of the Defect: The defect must have been present when the product left the manufacturer's control.
Unreasonably Dangerous: The defect makes the product unreasonably dangerous to the user or consumer.
Causation: The defect directly caused the injury or damage.
Example: A batch of cars is manufactured with improperly installed brakes. Even though the design specifications were adequate, the manufacturing process failed to meet these specifications, resulting in a defect.
*Manufacturing defect is an element of product strict liability (defect of product itself) as opposed to negligence (focus on the conduct of the manufacturer)
*Res ipsa loquitur could be a better solution because it’s easier to prove than the manufacturing defect
Design Defect
A design defect exists when the product is manufactured as intended, but the design itself is inherently unsafe. To prove a design defect, the following requirements are generally necessary:
Inherent Design Flaw: The product's design is inherently dangerous or defective.
Foreseeable Risk: The risk of harm posed by the design could have been reduced or avoided by the adoption of a reasonable alternative design.
Reasonable Alternative Design: A safer alternative design must have been economically and technologically feasible at the time the product was manufactured.
Unreasonably Dangerous: The design makes the product unreasonably dangerous to the user or consumer.
Causation: The defect directly caused the injury or damage.
Example: A car model is designed with a fuel tank positioned in such a way that it is prone to rupture in rear-end collisions. Even though the car is manufactured according to specifications, the design itself is considered defective because it poses an unnecessary risk of fire.
Legal Tests
Different jurisdictions may apply various legal tests to establish a design defect, including:
Consumer Expectations Test: Whether the product performed as safely as an ordinary consumer would expect when used in an intended or reasonably foreseeable manner.
Risk-Utility Test: Balancing the product's risks against its utility and the availability of a safer, feasible alternative design.
Hybrid Approach: Combining elements of both the Consumer Expectations Test and the Risk-Utility Test.
Design defect more likely to be on exam (e.g. automobile)
- More factors to consider (7 factors): These seven requirements collectively help establish whether a product's design is defective and unreasonably dangerous, potentially making the manufacturer liable for any resulting injuries or damages.
1.Inherent Danger in Design: The product design is inherently unsafe and poses a risk of harm when used as intended or in a reasonably foreseeable manner.
2.Foreseeability of Risk: The manufacturer should have foreseen the risk of harm posed by the design at the time the product was designed.
3.Reasonable Alternative Design: There was a feasible, safer alternative design available that could have reduced or eliminated the risk without compromising the product's functionality or increasing its cost significantly.
4.Feasibility of Alternative Design: The alternative design was economically and technologically feasible for the manufacturer to implement at the time the product was designed.
5.Risk-Utility Analysis: The court performs a risk-utility analysis, balancing the product's risks against its benefits to determine if the design's risks outweigh its utility. This includes considering factors like the severity of the potential harm, the likelihood of occurrence, and the product’s usefulness.
6.Compliance with Safety Standards: The product's design is evaluated against existing industry standards and regulations. Compliance with these standards may support the manufacturer's position, but it is not always conclusive.
7.Consumer Expectations: The product did not perform as safely as an ordinary consumer would expect when used in an intended or reasonably foreseeable manner. This often involves examining whether the design defect was something that an average consumer would anticipate.

If the user cannot understand the meaning of the warning, is it a warning defect? What’s the requirement for the warning defect?
In product liability law, a warning defect (also known as a failure-to-warn defect) occurs when a manufacturer fails to provide adequate warnings or instructions about the risks associated with the use of a product. For a warning to be considered adequate, it must be clear, conspicuous, and understandable to the average user. If the user cannot understand the meaning of the warning, it may indeed constitute a warning defect.
Factors Determining a Warning Defect
1.Clarity: The warning must be written in a language and manner that an average user can easily understand. Technical jargon, vague language, or overly complex instructions can render a warning ineffective.
2.Conspicuousness: The warning must be prominent and noticeable. It should be placed in a location where the user is likely to see it and should use formatting (e.g., bold text, bright colors) to draw attention.
3.Specificity: The warning must clearly describe the specific risks and potential hazards associated with the product. General warnings that do not detail the actual dangers may be insufficient.
4.Comprehensibility: The warning must be understandable to the intended audience. This includes considering the likely literacy level, language proficiency, and cultural background of the user base.
5.Instructions for Safe Use: The warning should include instructions for safe use and any necessary precautions to avoid the risk.
Legal Considerations
·Reasonable Person Standard: Courts often apply a "reasonable person" standard to determine whether a warning is adequate. This means that the warning should be understandable to an average person using the product.
·Foreseeable Misuse: The manufacturer must anticipate foreseeable misuse of the product and provide appropriate warnings. If a user cannot understand the warning, the manufacturer may be liable for failing to foresee this issue.
·Duty to Warn: Manufacturers have a duty to warn users about non-obvious risks that could arise from the normal use of their product. Failure to fulfill this duty can result in a warning defect.
Directed Verdict
A "directed verdict" is a ruling made by a judge in a jury trial, typically at the request of one of the parties, whereby the judge decides the case in favor of one party without allowing the jury to consider it. This can happen under certain circumstances where the judge determines that no reasonable jury could reach a different conclusion based on the presented evidence. Here's a more detailed explanation:
When a Directed Verdict Occurs
Timing: A directed verdict usually occurs after the plaintiff has presented all their evidence but before the case goes to the jury. It can also happen after both sides have presented their evidence.
Motion: One party (usually the defendant) will move for a directed verdict, arguing that the opposing party has failed to present sufficient evidence to support their case.
Criteria for a Directed Verdict
Insufficient Evidence: The judge grants a directed verdict when they believe that the evidence presented by the non-moving party (usually the plaintiff) is so insufficient that no reasonable jury could find in their favor.
Legal Standard: The judge applies a legal standard to determine whether, considering the evidence in the light most favorable to the non-moving party, a reasonable jury could find for that party. If not, the judge directs a verdict.
Implications of a Directed Verdict
Favorable to One Party: The judge effectively takes the decision out of the jury's hands, ruling in favor of one party. This typically results in a judgment as a matter of law for the party that requested the directed verdict.
Precludes Jury Deliberation: The jury does not get to deliberate or render a verdict on the case because the judge has determined that the evidence is insufficient to support any other outcome.
Example
Imagine a civil trial where the plaintiff is suing for damages based on an alleged breach of contract. After the plaintiff presents their case, the defendant may request a directed verdict, arguing that the plaintiff has not provided enough evidence to prove that a contract existed or that it was breached. If the judge agrees, they will grant a directed verdict in favor of the defendant, effectively ending the case without it going to the jury.
Legal Context
Federal and State Courts: Directed verdicts can be requested and granted in both federal and state courts, though specific rules and standards can vary by jurisdiction.
Judgment as a Matter of Law: In federal courts, a directed verdict is now referred to as a "judgment as a matter of law" (JMOL), governed by Rule 50 of the Federal Rules of Civil Procedure.
In summary, a directed verdict is a procedural mechanism used by judges to resolve a case without jury deliberation when the evidence presented is deemed legally insufficient to support a different outcome.
