  • Involve a foreseeable and highly significant risk of physical harm even when reasonable care is exercised by all parties (toxic waste disposal, keeping dangerous animals)
  • Not commonly engaged in by the general public
  • Risk cannot be eliminated by the exercise of reasonable care
  • Typically subject to strict liability rather than negligence standards which require a breach of duty

Factors for abnormally dangerous determination

  • of some harm to person, land or property of others ()
  • Likelihood that resulting harm will be substantial
  • Inability to eliminate risk through reasonable care
  • where carried out ( in residential area)
  • Extent to which activity's value to community is outweighed by dangerous attributes ( in populated areas)

Application of Restatement criteria

  • imposes strict liability for abnormally dangerous activities
    • Applies even if utmost care was used to prevent the harm
    • Limited to kind of harm that makes activity abnormally dangerous (ground damage from blasting but not worker injuries)
  • provides six factor test:
    1. High degree of risk of some harm to person, land or chattels
    2. Likelihood of great resulting harm
    3. Inability to eliminate risk with reasonable care
    4. Uncommon nature of activity
    5. Unsuitability to location
    6. Value to community outweighed by danger
  • Factors are weighed together, no single one determinative (crop dusting may be common but still abnormally dangerous due to high risk)

Policy rationale for strict liability

  • Fairness - party engaged in dangerous activity should bear costs rather than innocent victims (neighboring landowners)
  • Incentives - strict liability encourages risk reduction beyond reasonable care and efficient activity levels since full accident costs are internalized
  • Loss spreading - allows costs to be distributed through insurance and pricing rather than falling solely on victims
  • Administrative efficiency - avoids litigation over fault required in negligence cases

Key Terms to Review (23)

Abnormally Dangerous Activities: Abnormally dangerous activities refer to actions or undertakings that inherently involve a high risk of significant harm to people or property, even when all appropriate safety measures are taken. These activities are characterized by their uncommon nature and the potential for severe consequences, leading to strict liability for any resulting damages. This concept is crucial in understanding how liability is assigned in tort law, especially concerning categories of torts and statutory strict liability.
Administrative Efficiency: Administrative efficiency refers to the effectiveness and productivity of an organization in managing its operations, processes, and resources to achieve desired outcomes. It focuses on minimizing waste, optimizing workflows, and ensuring that decision-making is streamlined, particularly in the context of regulatory frameworks governing potentially hazardous activities.
Community value: Community value refers to the worth or importance of a particular activity or resource as determined by the community’s needs, interests, and well-being. This concept plays a crucial role in evaluating whether an activity, especially those deemed abnormally dangerous, serves a significant benefit to society that may outweigh the inherent risks involved.
Degree of Risk: Degree of risk refers to the likelihood and severity of harm that can arise from certain activities or actions. In the context of liability, it helps determine how dangerous an activity is and whether it should be classified as abnormally dangerous, which can lead to strict liability for any resulting harm.
Explosives manufacturing: Explosives manufacturing involves the production of substances that can undergo rapid chemical reactions to produce gas and heat, often resulting in an explosion. This process is closely linked to activities that are considered abnormally dangerous due to the inherent risks of handling and storing explosive materials, making it a focus of strict regulations and liability considerations.
Fairness: Fairness refers to the equitable treatment of individuals in legal contexts, ensuring that rights and responsibilities are balanced and justly applied. In the realm of liability, particularly concerning abnormally dangerous activities, fairness is essential in determining who is responsible for harm caused by such activities, taking into account the inherent risks involved and the expectations of safety for affected parties.
Fireworks storage: Fireworks storage refers to the methods and facilities used to keep explosive materials, such as fireworks, in a safe and compliant manner. This term is crucial because it involves specific regulations and practices aimed at minimizing risks associated with flammable substances and ensuring public safety.
High degree of risk: A high degree of risk refers to the significant potential for harm or injury associated with certain activities that are inherently dangerous. This concept is pivotal in determining liability, particularly when assessing whether an activity is abnormally dangerous. When an activity involves a high degree of risk, the law often places strict liability on those who engage in such activities, meaning they can be held responsible for damages regardless of fault or negligence.
Incentives for risk reduction: Incentives for risk reduction are mechanisms or motivations that encourage individuals or organizations to take steps to minimize the likelihood of harm or injury associated with potentially dangerous activities. These incentives can take various forms, including financial rewards, regulatory requirements, and social pressures that collectively aim to promote safer practices in activities deemed abnormally dangerous.
Keeping Dangerous Animals: Keeping dangerous animals refers to the legal responsibility of individuals who own or possess animals that pose a significant risk to others. This concept is tied to the idea that owners may be held liable for any harm caused by their animals, particularly if the animals are classified as inherently dangerous or are kept in a manner that increases the risk of injury. The responsibility stems from the need to protect the public from potential dangers associated with these animals and can lead to strict liability in cases of injury.
Likelihood of harm: Likelihood of harm refers to the probability or chance that an action or activity will cause injury or damage. It plays a crucial role in determining whether an activity is considered abnormally dangerous and helps assess the level of care needed to mitigate risks associated with that activity.
Loss Spreading: Loss spreading refers to the concept of distributing or sharing the financial burden of a loss across a wider group rather than allowing a single individual or entity to bear the entire impact. This mechanism is crucial in contexts involving abnormally dangerous activities, where the risks associated with such activities can lead to significant harm. By spreading the potential losses, it encourages safer practices and provides a system for compensating victims without placing an overwhelming financial strain on one party.
Negligence Standards: Negligence standards refer to the legal benchmarks used to determine whether an individual's conduct falls below the level of care expected to prevent harm to others. These standards focus on the behavior of a 'reasonable person' and evaluate whether a defendant's actions can be deemed careless, leading to liability for any resulting damages. This concept is crucial in assessing liability in various contexts, especially when dealing with activities that could be considered abnormally dangerous.
Policy rationale: Policy rationale refers to the underlying reasoning and justifications for creating and enforcing legal rules and standards, particularly in tort law. It addresses why certain activities, like abnormally dangerous activities, are treated differently under the law due to their inherent risks, guiding decisions on liability and compensation. This rationale shapes how courts approach cases and ultimately influences public safety and risk management.
Reasonable Care: Reasonable care refers to the level of caution and concern an ordinary person would exercise in a given situation. This concept is essential in determining liability in various contexts, as it establishes a standard against which a person's actions can be measured. The application of reasonable care is crucial in understanding how products should be manufactured, designed, and marketed, as well as evaluating the risks associated with certain activities.
Recreational Blasting: Recreational blasting refers to the practice of using explosives for activities such as rock climbing, skiing, or mining in a non-commercial context. This type of blasting is typically done for personal enjoyment or recreational purposes rather than for profit, and it poses specific risks and liabilities due to the potential for injury or property damage.
Restatement (Second) of Torts §519: Restatement (Second) of Torts §519 outlines the legal standards for determining liability in cases involving abnormally dangerous activities. It establishes that a person engaging in such activities is subject to strict liability for any harm caused by the activity, regardless of the precautions taken. This section aims to protect individuals from the inherent risks associated with certain high-risk actions.
Restatement (Second) of Torts §520: Restatement (Second) of Torts §520 outlines the criteria for determining whether an activity is considered abnormally dangerous, which can lead to strict liability for any harm caused by that activity. This section highlights factors such as the risk of serious harm, the inability to eliminate the risk with reasonable care, and whether the activity is not commonly performed in the community. Understanding this restatement helps clarify the legal standards applied in tort cases involving dangerous activities and their implications for liability.
Strict Liability: Strict liability is a legal doctrine holding individuals or entities responsible for their actions or products, regardless of fault or intent. This principle is especially relevant in cases involving defective products, abnormally dangerous activities, and certain animal-related injuries, emphasizing the need for accountability without proving negligence.
Substantial Harm: Substantial harm refers to significant damage or injury that goes beyond minor inconveniences and has a serious impact on a person or property. This concept is crucial in determining liability in tort cases, particularly when assessing whether a defendant's actions caused enough harm to warrant compensation or legal remedy.
Toxic waste disposal: Toxic waste disposal refers to the process of managing and eliminating waste that poses significant risks to human health and the environment due to its hazardous nature. This includes waste materials from industrial processes, medical facilities, and chemical plants that can cause serious harm if not handled properly. The safe disposal of toxic waste is crucial because it prevents contamination of land, water, and air, and reduces the risk of exposure to harmful substances.
Uncommon nature of the activity: The uncommon nature of the activity refers to activities that are not typically engaged in by the general public and carry an inherent risk of harm that is significantly higher than that of ordinary activities. Such activities often lead to a greater likelihood of causing injury or damage, which can result in stricter liability standards for those who engage in them. Understanding this concept is crucial because it helps in determining when liability may be imposed, even if no negligence can be established.
Unsuitability of activity to location: Unsuitability of activity to location refers to a legal concept that evaluates whether an activity is appropriate or safe for its specific geographical context. This principle plays a crucial role in determining liability when harm arises from activities that may be inherently dangerous or inappropriate for the surrounding environment. An activity deemed unsuitable for its location may be subjected to stricter liability standards, especially if it poses risks that the locality cannot reasonably mitigate.
