Introduction

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

Unit 7 — Negotiable Instruments

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

Key Concepts

Main Types: check, promissory note, bill of exchange.
Common Parties: issuer (drawer), drawee, beneficiary (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

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

Types

Public Nuisance: affects the rights or safety of the community.
Private Nuisance: affects an individual or a limited number of people in relation to their property.

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

Comparative Table — Public vs. Private Nuisance

Element	Public	Private
Affected Parties	Community	Specific Individuals
Typical Remedies	Public 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 a legal doctrine that holds parties responsible for damages without the need to prove fault or negligence.

Typical Applications

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

Practical Example: If a company stores explosive materials and an explosion occurs, damaging nearby homes, the company may be held liable under strict liability.

Quick Comparison — Fault-Based vs. Strict Liability

Element	Fault-Based	Strict Liability
Need to prove negligence	Yes	No
Common Scenarios	Car accidents, 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 versus a design that causes tipping under normal conditions.

Comparative Table — Types of Defects

Type	Origin	Typical Claim
Manufacturing	Isolated production	Damage to specific unit
Design	Product design	Potential class action
Warning	Insufficient information	Injuries from intended use

💡 Did you know?Did you know that in some systems, the burden of proof for the defect can be reversed, and it falls to the manufacturer to prove the product's safety?

Unit 11 — Contracts: General Concepts

A contract is a legally binding agreement between two or more partie
