Product Liability Claims: Manufacturing Defect, Design, Failure to Warn

Negligence is a tort cause of action where the main difference from intentional torts is intent—negligence involves unintentional harm. Strict liability is an extreme doctrine where defendants have no defenses, applied only to inherently dangerous activities. Negligence requires conduct below the legal standard that causes harm. Society imposes duties on people, and breach of those duties creates liability only when actual harm occurs.

The primary difference between negligence and strict liability is that negligence requires proof of breach of duty, while strict liability does not require proof of fault. Negligence involves proving that a party failed to meet the standard of care, whereas strict liability applies regardless of fault.

Strict liability differs fundamentally from negligence-based liability in several critical ways. First, strict liability applies to inherently dangerous activities where harm is a natural consequence of the activity itself, not caused by any external factor. Second, strict liability applies to commercial activities but not to non-commercial contexts like housing societies, where only negligence liability applies. Third, strict liability imposes liability regardless of whether the owner was personally at fault or whether they took all reasonable precautions. Fourth, strict liability holds owners liable even when independent contractors cause the harm, as the owner created the dangerous situation by engaging the contractor. Fifth, strict liability requires compensation for all damages to third parties without allowing the owner to limit liability by blaming others. These distinctions ensure that those who benefit from dangerous activities bear ultimate responsibility for any resulting harm.

Strict liability (Rylands v Fletcher rule) attaches without fault where a person keeps a thing for their own purpose and it escapes causing mischief. The plaintiff must prove the damage was caused by a thing brought by the defendant that was not a natural user of land and escaped. Negligence (carelessness or inadvertence) requires three elements: duty to take care, breach of that duty, and consequential damage. The defendant may have no bad intention but failed to take necessary care to avoid consequences. These two liability types represent different approaches: strict liability imposes responsibility regardless of fault, while negligence requires establishing a failure to meet the standard of care.

The concept of causation (السببيه) in Islamic philosophy states that every created thing (الحادث) must have a creator (موجد) and a cause (محدث). A 'حادث' is defined as something that has a beginning and was brought into existence. This principle establishes that nothing in the universe exists without a cause or origin, which is fundamental to understanding the existence of Allah as the ultimate creator.

Robin Le Poidevin proposes that causation is a primitive concept—something that cannot be explained in terms of other concepts, but rather other concepts should be explained in terms of causation. He suggests that features of causation can explain features of time, particularly the direction of time. The difference between earlier and later is fundamentally a causal difference, meaning that what we call 'earlier' is defined in causal terms because causes occur before their effects not accidentally but essentially.

Causation is not an inherent connection between phenomena but rather a mental habit formed through repeated observation; to establish causation, one must verify that the cause consistently precedes the effect, that the effect does not occur without the cause, and that changes in the cause produce corresponding changes in the effect, though this relationship remains probabilistic rather than absolute certainty.

In Buddhism, all phenomena arise from causes and conditions (เหตุปัจจัย). The mind (จิต) plays a central role in causation. The speaker explains that the mind is the primary factor in determining whether actions are good or bad. When the mind is defiled, actions become evil; when the mind is pure, actions become good. The Law of Karma states that actions have consequences, and this law operates automatically and cannot be changed. The Four Foundations of Mindfulness (สติปัฏฐาน 4) are the foundation of Buddhist meditation: body, feelings, mind, and mental objects. The Eightfold Path (อริยมรรค 8) consists of eight factors: right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration.

This segment explains Quranic verse 18:50 about people we perceive in our Nefentric Universe. These entities cannot provide support because there are no empires for these apparitions in our universe. If we invite them to guidance, they do not hear because they are apparitions. This eliminates the concept of causation as we understand it. What we see as causation is just a way to ease our perception, but every event is actually caused by Allah directly. The Quran teaches that Allah informs through everything, and everything we observe is part of our field of receiving information.

The simple act of buying and selling constitutes a legal relation in itself. Whether this relation is expressed through written law or exists within a developed legal system, the fundamental nature remains the same. The speaker emphasizes that the intention to sell something already embodies a legal relation, as it involves the bilateral exchange of rights and obligations between parties.

Legal relationships form through expression of intent (의사표시), which is the external manifestation of internal will. When parties express matching intentions (e.g., one wants to sell and the other wants to buy), a legal relationship is created. In a sale (매매), the seller gains the right to receive payment and the obligation to transfer property, while the buyer gains the right to receive property and the obligation to pay. This demonstrates how matching expressions of intent create reciprocal rights and obligations.

This lesson covers the four types of buyer-seller relationships in entrepreneurship: (1) Transactional - no interest in ongoing relationships, focused on best price, willing to switch sellers; (2) Habitual - limited ongoing relationships based on convenience and habit; (3) Affiliative - relationships built on trust and seller expertise, where buyers rely on seller recommendations; (4) Strategic - deep commitment where both parties invest time and money to expand mutual opportunities, often compared to marriage. Understanding these relationship types is essential for business success.

The relationship between buyers and sellers originates from the exchange of goods and services. A buyer uses money to purchase goods and services for daily needs, while a seller offers products or services in exchange for money. Producers create goods using factors of production like land, capital, and labor, and consumers benefit from these products. Proper seller conduct includes selling quality goods at fair prices, being honest, and treating customers politely. Proper buyer conduct involves comparing prices and quality, checking product standards, practicing thriftiness, and planning expenses wisely. This exchange creates mutual benefit when both parties follow appropriate practices.

In a sales contract, there are two parties: the buyer (kharidara) and the seller (vikreta). A contract (sannivada) is established between them, which is the most important element in any business transaction. Both parties have specific rights and obligations under this contract. When either party fails to fulfill their obligations according to the contract, the other party has the right to take legal action against them.
