Introduction

Civil liability and contracts are pillars of civil law that govern relationships between individuals and businesses when harm arises or when obligations are created. This material explains essential concepts, breaks them down into manageable parts, and provides practical examples to aid your university studies.

Unit 7 — Negotiable Instruments

A negotiable instrument is a written document that guarantees the payment of a specified amount of money to a person or to the bearer.

Key Concepts

Main Types: check, promissory note, bill of exchange.
Common Parties: drawer, drawee, payee.
Characteristics: transferable by endorsement, maturity date, signature.

Practical Example: A merchant issues a 90-day promissory note to a supplier; the supplier can endorse it to another company as a form of payment.

Unit 8 — Nuisance Concepts (Disturbance)

Nuisance is an act that interferes with another person's use or enjoyment of property.

Types

Public Nuisance: affects the rights or safety of the community.
Private Nuisance: affects an individual or a small group of people in their use or enjoyment of property.

Example: A workshop that generates constant noise and fumes can be a private nuisance for neighbors and a public nuisance if it affects the public way.

Comparison Table — Public vs. Private Nuisance

Element	Public	Private
Affected Parties	Community	Specific Individuals
Typical Remedies	Public enforcement actions, closure	Damages, injunctive relief

💡 Did you know?Fun fact: Did you know that in some jurisdictions a lawful activity can be considered a nuisance if its intensity or duration exceeds what is socially tolerable?

Unit 9 — Strict Liability

Strict liability is the doctrine that holds parties responsible for damages without the need to prove fault or negligence.

Typical Applications

Dangerous animals
Abnormally dangerous activities (e.g., explosives, handling hazardous materials)
Defective products under certain standards

Practical Example: If a company is engaged in storing explosive materials and an explosion occurs that damages nearby homes, the company may be held liable under strict liability.

Quick Table — Fault-Based vs. Strict Liability

Element	Fault-Based	Strict Liability
Need to prove negligence	Yes	No
Common Areas	Car accidents, medical malpractice	Ultrahazardous activities, some products

Unit 10 — Product Liability

Product liability is the obligation of manufacturers and sellers for damages caused by defective products.

Types of Defects

Manufacturing Defect: an error in producing a specific unit.
Design Defect: a flaw in the design that affects the entire product line.
Failure to Warn: lack of information about risks and safe use.

Example: An appliance that sparks due to poor manufacturing vs. a design that causes tipping under normal conditions.

Comparison Table — Types of Defects

Type	Origin	Typical Claim
Manufacturing	Individual unit production	Damage to a specific unit
Design	Product design	Class action possible
Warning	Insufficient information	Injuries from intended use

💡 Did you know?Did you know that in some systems, the burden of proof for a defect can be reversed, requiring the manufacturer to demonstrate the product's safety?
