Introduction to Law and Legal System (LAW-1107) – Comprehensive Study Notes

Course Overview

PART 1: What is Law?

1.1 Defining Law

Law can be defined as a system of rules and regulations that governs the conduct of individuals and organizations within a society. It is enforced by the state and backed by sanctions (penalties) for non-compliance.

Key Characteristics of Law:

Law vs. Other Social Norms:

1.2 Functions of Law in Society

PART 2: Classifications of Law

Law is broadly divided into two major categories: Public Law and Private Law.

2.1 Public Law

Public law governs the relationship between individuals (and private organizations) and the state. It deals with the structure of government, the powers of officials, and the rights of citizens against the state.

2.2 Private Law (Civil Law)

Private law (often called civil law) governs relationships between private individuals and organizations. The state acts as an umpire (judge) rather than a party.

2.3 Substantive vs. Procedural Law

PART 3: Sources of Law (Primary)

Primary sources of law are the official texts that establish legal rules and obligations. Each branch of government produces law in distinct forms.

3.1 The Constitution (The Supreme Law)

The Constitution is the highest legal authority in a state. All other laws must conform to it; any law that violates the Constitution can be declared void (ultra vires) by the courts.

Constitution of Pakistan (1973):

• Supreme law of Pakistan

• Enforced on August 14, 1973 (independence day)

• Establishes Pakistan as an Islamic Federal Republic (Article 1).

• Declares Islam as the state religion (Article 2).

• Provides for a parliamentary form of government (President as head of state; Prime Minister as chief executive).

• Enumerates Fundamental Rights (Articles 8–28): Right to life, liberty, equality, freedom of speech, freedom of religion, etc.

• Includes Directive Principles of State Policy (Articles 29–40) – guidelines for governance (not enforceable in court, but fundamental in governance).

• Amended many times (27 amendments as of 2025–2026).

3.2 Legislation (Statutes/Acts of Parliament)

Legislation is law enacted by a legislative body (Parliament at the federal level; Provincial Assemblies at the provincial level). It is also called statutory law.

Legislative Process in Pakistan (Simplified):

Types of Legislation:

Pakistan Code: The official codified compilation of all federal laws, arranged by subject.

3.3 Case Law (Judicial Precedent / Common Law)

Case law consists of legal principles established by judges in their written decisions (judgments). Pakistan follows the common law system (inherited from British India), where judicial precedent (stare decisis) is binding.

Doctrine of Precedent (Stare Decisis – Latin: “to stand by decided matters”):

• Lower courts must follow decisions of higher courts in the same jurisdiction (binding precedent).

• Courts at the same level generally follow their own prior decisions (horizontal stare decisis).

• Higher courts may overrule their own prior decisions (or lower courts’ decisions) in exceptional circumstances (changes in law, social conditions, or earlier error).

Hierarchy of Precedent (Pakistan):

Case Reporters in Pakistan (where case law is published):

• PLD (Pakistan Legal Decisions) – most widely cited

• SCMR (Supreme Court Monthly Review)

• PCrLJ (Pakistan Criminal Law Journal)

• MLD (Monthly Law Digest)

• CLC (Corporate Law Cases)

• PTD (Pakistan Tax Decisions)

Concepts of Obiter Dicta and Ratio Decidendi:

3.4 Customary Law

Custom refers to long-established practices that have acquired the force of law through consistent, widespread, and accepted usage over time.

3.5 Islamic Law (Shari’ah)

Pakistan was established as an ideological state based on Islam. Islamic law influences the legal system at multiple levels.

Institutional Incorporation of Islamic Law:

3.6 International Law and Treaties

When Pakistan ratifies an international treaty (e.g., UN Charter, human rights covenants, trade agreements), principles may be incorporated into domestic law through specific legislation. Courts may refer to international law as a persuasive source (especially in interpreting fundamental rights).

PART 4: Legal System of Pakistan

4.1 Historical Foundations

Pakistan’s legal system is primarily based on English common law but has been modified by Islamic law (Shari’ah) and subsequent statutes.

Key Influences:

• English Common Law: Adversarial system, judicial precedent (stare decisis), concepts of equity, habeas corpus, bail, etc..

• Islamic Law (Shari’ah): Hudood laws (criminal penalties), law of evidence (Qanun-e-Shahadat), inheritance (Muslim personal law), marriage, divorce (Muslim Family Laws Ordinance), waqf (religious endowments).

• Codified Laws (British Indian legacy): Most substantive laws (Penal Code, Contract Act, etc.) remain statute-based (codified), though courts interpret them using common law method.

4.2 The Structure of Government (Constitutional Framework)

4.3 The Judicial Hierarchy (Court Structure)

Pakistan has a hierarchical court system, with higher courts binding lower courts (stare decisis).

4.4 Key Judicial Bodies and Their Functions

4.5 Judges and Juries

• No jury system in Pakistan (civil or criminal trials). Judges are sole arbiters of law and fact.

• Adversarial system (both sides present evidence and arguments before neutral judge).

• Juries were phased out after independence; Pakistani judges criticized jury trials as “amateur justice”.

PART 5: Key Substantive Laws of Pakistan

5.1 Civil Laws

5.2 Criminal Laws

5.3 Islamic and Family Laws

5.4 Constitutional Law (Fundamental Rights – 1973 Constitution, Articles 8–28)

(Courts can enforce these rights through constitutional petitions – writs under Article 199 in High Courts and Article 184(3) in Supreme Court.)

PART 6: Key Procedural Concepts

6.1 Civil Procedure

6.2 Criminal Procedure

PART 7: Alternative Dispute Resolution (ADR)

Litigation is not the only method for resolving disputes. Alternative Dispute Resolution (ADR) refers to processes that avoid formal court trials.

ADR is increasingly encouraged (and sometimes mandated) for commercial, family, and certain civil disputes to reduce court backlog and expedite resolution.

Study Notes: Environmental Sciences and Law

1. Course Overview: The Intersection of Science and Law

Environmental law is, by its very nature, an interdisciplinary field . It does not exist in a vacuum but is fundamentally grounded in the scientific understanding of ecological systems, chemical processes, and biological interactions . Policy-making requires scientific data, and decision-making involves complex questions that demand scientific answers .

1.1 A Simple Model: Science Informing Law

The relationship can be visualized as a cycle:

1. Scientific Discovery: Researchers identify an environmental problem (e.g., ozone depletion, climate change).

2. Risk Assessment: Scientists evaluate the severity and probability of the threat.

3. Legal Response: Legislators and agencies draft laws, regulations, and treaties based on this evidence to mitigate the harm.

4. Implementation & Feedback: Laws are enforced, and scientific monitoring continues to measure effectiveness, leading to revisions.

1.2 Key Challenges at the Interface

A major challenge lies in the difference between scientific and legal thinking .

• Science is often probabilistic, tentative, and evolving (dealing in hypotheses and uncertainty).

• Law seeks finality, certainty, and definitive standards of proof (e.g., “beyond a reasonable doubt” or “balance of probabilities”).

Core Idea: Environmental law must be dynamic enough to incorporate evolving scientific knowledge while maintaining legal stability . This is often achieved through concepts like the precautionary principle and adaptive management .

2. The Natural Science Foundation

To regulate environmental harm, one must first understand the natural systems being protected.

2.1 Ecology: The Blueprint for Environmental Law

Ecology is the study of the relationships between living organisms and their environment . It provides the scientific rationale for many laws.

2.2 Chemistry & Toxicology: Understanding Pollution

Chemistry explains what pollutants are, how they move, and their toxic effects .

• Toxicology: The study of poisons and their effects.

  • Dose-Response Relationship: A fundamental principle where the effect of a chemical depends on the concentration and duration of exposure.

  • Bioaccumulation: The build-up of toxins (like mercury or DDT) in an organism’s body over time.

  • Biomagnification: The increase in concentration of a toxin as it moves up the food chain (from plankton → fish → birds of prey).

• Persistence: How long a chemical remains in the environment (e.g., DDT, PCBs).

• Fate and Transport: How a chemical moves through air, water, and soil.

2.3 Earth Science & Climate Physics

• Hydrology: Understanding water cycles is essential for water rights laws, floodplain management, and groundwater protection.

• Climate Science: Physics explains the greenhouse gas effect, allowing laws to target specific emissions (e.g., the Kyoto Protocol, Clean Air Act) .

• Geology: Relevant to mining laws, fracking regulations, and nuclear waste disposal (siting of repositories).

3. Core Principles of Environmental Law (from Science)

Modern environmental law has developed key principles to translate scientific realities into legal obligations .

3.1 The Precautionary Principle (PP)

• Scientific Driver: Uncertainty. Science cannot always prove a causal link between an activity and future harm until it is too late.

• Legal Formulation: “Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.”

• In Practice: Shifts the burden of proof. Instead of the public proving harm, the proponent of the activity must prove it is safe.

• Case Example: The Leatch v. National Parks & Wildlife Service (1993, NSW) case was an early judicial consideration of the principle in the context of protecting an endangered frog species .

3.2 The Polluter Pays Principle (PPP)

• Scientific Driver: Economics of externalities. The social costs of pollution (e.g., healthcare, clean-up) are often not included in the market price of goods.

• Legal Formulation: The polluter should bear the cost of pollution prevention and control measures.

• In Practice: Fines for oil spills, Superfund laws requiring clean-up of hazardous waste sites, and “green taxes” on carbon emissions.

3.3 Sustainable Development

• Scientific Driver: Resource depletion (e.g., fisheries collapse, deforestation).

• Legal Formulation: Meeting the needs of the present without compromising the ability of future generations to meet their own needs.

• Integration Principle: Requires the integration of environmental protection into economic and social development policies .

3.4 Public Participation & Access to Information

• Scientific Driver: Democratization of science. Recognizing that local communities often have valuable ecological knowledge (Traditional Knowledge) and that transparency improves environmental outcomes (e.g., Right-to-Know laws regarding toxic emissions) .

4. The Science-Law Interface (SPI)

The Science-Policy Interface (SPI) refers to the social processes that allow for the exchange and joint construction of knowledge between scientists and decision-makers to enrich policy .

4.1 Mechanisms for Managing the Interface

4.2 The Evidentiary Challenge in Court

When environmental disputes go to court, judges face difficult questions: What is the standard of proof? 

• Civil (Tort) Standard: “Balance of probabilities” (more likely than not; >50%).

• Criminal/Serious Charges Standard: “Beyond a reasonable doubt” (>95%).

• Environmental “Sweet Spot”: Clear and convincing evidence (A middle standard: high probability, >75%). International courts like the ICJ have often used this standard in environmental cases (e.g., Pulp Mills on the River Uruguay case, 2010) because environmental harm is complex but rarely reaches “beyond a reasonable doubt” .

Reference: International environmental jurisprudence is evolving. The ITLOS (2024) and ICJ (2025) Advisory Opinions on Climate Change have reinforced the duty of states to exercise due diligence based on the best available science .

5. Major Environmental Laws & Their Scientific Basis (US/International Focus)

Here is a look at how specific laws are built on scientific concepts .

6. Key Terminology & Legal Tests

• Due Diligence (Environmental Context): The obligation of a state to take all appropriate measures to prevent significant transboundary environmental harm. This is a “dynamic” standard that changes as science improves .

• Cumulative Impacts: The combined, additive, and synergistic effects of past, present, and reasonably foreseeable future actions (e.g., a new factory built next to a major highway in a smoggy city). Many laws struggle to regulate this “death by a thousand cuts” .

• Standing (Locus Standi): The right of a party to bring a lawsuit. Environmental groups often struggle to prove they have been “specifically injured” by a diffuse problem like climate change, though this is changing (e.g., Juliana v. United States).

• Due Process: The legal requirement that the state must respect all legal rights owed to a person. In environmental law, this conflicts with the urgency of climate action, requiring transparent and fair procedures for regulatory changes .

Summary for Revision

1. Interdependence: Environmental law relies on ecology (systems), chemistry (pollutants), and physics (climate/energy).

2. Key Principles: Understand the Precautionary Principle (act despite uncertainty), Polluter Pays (internalize costs), and Sustainability (inter-generational equity).

3. The Interface (SPI): Science informs policy via EIA, Risk Assessment, and Adaptive Management.

4. Standard of Proof: Courts try to bridge the gap between scientific uncertainty and legal finality using standards like “clear and convincing evidence.”

5. Due Diligence: The legal duty to keep up with the “best available science” .

Self-Test Questions

1. Explain the fundamental difference between how a scientist treats “uncertainty” and how a judge treats “uncertainty.”

2. If a new chemical is suspected of causing cancer but the data is unclear (10 years needed for proof), which environmental law principle gives the EPA authority to regulate it now?

3. Name one reason why the “Balance of Probabilities” standard is often criticized in toxic tort (pollution poisoning) cases.

4. How does the science of “bioaccumulation” justify stricter legal controls on heavy metals like mercury compared to less persistent chemicals?

5. What is the practical purpose of “Environmental Impact Assessment” (EIA) in the scientific process of decision-making?

LAW-1202: LAW OF TORTS – Complete Study Notes

PART 1: INTRODUCTION TO THE LAW OF TORTS

1.1 Definition and Purpose

Definition: A tort (from Latin tortus – twisted) is a civil wrong, other than a breach of contract, for which the law provides a remedy (usually damages). Tort law protects individuals against wrongful acts by others that cause harm to person, property, reputation, or economic interests.

Purpose of tort law:

1.2 Tort Distinguished from Other Areas of Law

Example (overlap – same act can be both tort and crime): A person who assaults another (battery) can be:

• Criminally prosecuted by the state (fine or imprisonment)

• Sued in tort by the victim (damages for medical bills, pain and suffering)

1.3 Sources of Tort Law

1.4 Classification of Torts

PART 2: TRESPASS TO THE PERSON

2.1 Battery

Definition: The intentional and direct application of force to another person without lawful justification.

Elements:

Case (Cole v Turner, 1704): “The least touching of another in anger is a battery.” – but also without anger (unwanted friendly touch) can be battery if offensive.

Case (Collins v Wilcock, 1984): Police officer took woman’s arm to restrain her – held to be battery (not authorized detention). No hostility required; the act itself is the wrong.

Examples of battery:

Defences to battery:

• Consent (express or implied – e.g., sports, normal social contact)

• Self-defence (reasonable force)

• Lawful authority (police arrest, lawful correction – limited)

2.2 Assault

Definition: An intentional act that causes another person to reasonably apprehend immediate, direct, and unlawful personal violence.

Key distinction – Assault vs. Battery:

Elements of assault:

Case (Tuberville v Savage, 1669): “If it were not assize time, I would not take such language” – held NOT an assault. Words showed no immediate intent. Conditional threat (“if…”) may negate imminence.

Case (Stephens v Myers, 1830): Chairperson at meeting advanced toward plaintiff with clenched fist but was stopped before reaching him – held assault (caused reasonable apprehension of immediate battery).

Words alone as assault?

2.3 False Imprisonment

Definition: The intentional and total restraint of a person’s freedom of movement without lawful justification.

Elements:

Forms of imprisonment:

Case (Bird v Jones, 1845): Bridge partially closed; plaintiff could not go forward but could turn back. Held: NOT false imprisonment (not total restraint – alternative route existed).

Case (R v Governor of Brockhill Prison, ex p Evans, 2000): Prisoner held beyond correct release date due to miscalculation – false imprisonment. Even if prison authorities acted in good faith, mistake of law does not justify detention.

Duration: False imprisonment is actionable per se (without proof of actual damage). The slightest restraint suffices, though damages reflect duration and circumstances.

Defences:

• Lawful arrest (police reasonable grounds, citizen’s arrest for felony – common law; now regulated by statute)

• Parental authority (reasonable discipline)

• Legal authority (statute authorizing detention – mental health legislation)

• Consent (voluntary submission – but difficult to prove).

2.4 Intentional Infliction of Emotional Distress (IIED)

Also known as the tort of outrage (US) or Wilkinson v Downton tort (UK/Canada).

Definition: Intentional or reckless conduct that is extreme and outrageous, causing severe emotional distress.

Elements (US Restatement (Second) of Torts §46):

Case (Wilkinson v Downton, 1897 – UK origin): Defendant falsely told plaintiff her husband had been severely injured. Plaintiff suffered nervous shock (vomiting, other physical symptoms). Held: liable for willful act calculated to cause physical harm (precursor to IIED).

Examples:

Relationship to other torts:

• May overlap with assault (fear of battery) or battery

• Often used where no physical contact or imprisonment

PART 3: NEGLIGENCE

3.1 Overview

Definition: Negligence is the breach of a legal duty to take reasonable care that results in damage to the claimant.

The four elements of negligence (must all be proven):

3.2 Duty of Care

Historical development:

Modern tripartite test for duty of care (Caparo Industries plc v Dickman, 1990 – UK):

Example (duty of care scenarios):

• Driver to pedestrian: Foreseeable harm; proximity (road users); fair to impose duty → duty exists

• Lawyer to opposing party: Foreseeable? Possibly. Proximity? No (lawyer’s duty to client, not adversary) → no duty

• Police to victim of crime (failing to protect): Public policy generally excludes duty (policy reasons: floodgates, resource allocation)

Special duty situations:

3.3 Breach of Duty (Standard of Care)

The reasonable person standard: The defendant’s conduct is compared to what a reasonable person in the same circumstances would have done.

Objective test (not subjective – not about defendant’s personal limitations):

Factors in determining breach of duty:

The Bolam Test (professional negligence – medical, legal, engineering):

“A professional is not negligent if they have acted in accordance with a practice accepted as proper by a responsible body of members of the profession.”

• Modified in UK (Montgomery v Lanarkshire Health Board, 2015 – informed consent requires patient-centered information, not professional custom)

3.4 Causation

Two-stage test (both must be satisfied):

Problems with factual causation:

Thin skull rule (eggshell skull rule):

• Defendant takes the victim as they find them (including pre-existing vulnerability).

• Does not apply to unforeseeable type of damage – only to unforeseeable extent.

Example (thin skull rule): Defendant negligently bumps into employee. Employee has rare bone disease; arm shatters. Defendant liable for shattered arm (even though unforeseeable), because it was physical injury (foreseeable type) of unforeseeable severity.

Novus actus interveniens (intervening act breaks chain of causation):

3.5 Defences to Negligence

Limitation periods: Most tort actions must be brought within a statutory time limit (e.g., 2-6 years from date of damage or date of discovery, depending on jurisdiction). Medical negligence often has longer discovery period.

PART 4: OCCUPIERS’ LIABILITY

4.1 Definition and Scope

Definition: Liability of a person who occupies or controls premises for harm caused to entrants on the premises due to the state of the premises or activities on them.

Who is an occupier?

• Person with sufficient degree of control over premises.

• More than one person can be occupier (shared control).

Premises: Land, buildings, fixed structures, vehicles, ships, aircraft.

4.2 Common Law Categories (Pre-statute – still relevant for interpretation)

4.3 Modern Statutory Regimes (Many common law jurisdictions have replaced common law with statutes)

UK: Occupiers’ Liability Act 1957 (lawful visitors) + OLA 1984 (trespassers)

Canada: Occupiers’ Liability Acts (varies by province) – one duty to all entrants (except trespassers where different standard)

Example (Canada – Ontario Occupiers’ Liability Act): Occupier owes duty to take reasonable care to see that person entering premises, and property on premises, is reasonably safe – regardless of category of entrant (uniform standard).

Defences:

• Warning (if sufficient to enable visitor to be reasonably safe)

• Independent contractor (occupier may not be liable for work done by independent contractor if reasonable to rely on them)

• Contributory negligence of entrant

• Exclusion of liability by notice (subject to limits – cannot exclude liability for personal injury in consumer settings in some jurisdictions)

Case (Mourton v Poulter, 1930 – common law trespasser example, still influential): Children trespasser into railway yard; injured by temporary obstruction (slip). Railway not liable – no duty to trespasser except for deliberate harm or reckless conduct after discovery of presence. Modern statutes (UK OLA 1984) now impose duty to trespassers for all reasonable foreseeable injury.

PART 5: NUISANCE

5.1 Private Nuisance

Definition: Unlawful interference with a person’s use or enjoyment of land, or with rights over land.

Elements:

Types of private nuisance:

Case (Sturges v Bridgman, 1879): Doctor’s consulting room, neighbor confectioner’s machinery vibration. Doctor used room for quiet; after 20 years, doctor complained. Held: nuisance not established by “coming to the nuisance” – but locality matters (residential vs. industrial).

Defences to private nuisance:

5.2 Public Nuisance

Definition: An act or omission that materially affects the reasonable comfort and convenience of a class of Her Majesty’s subjects (or public).

Key differences from private nuisance:

Examples of public nuisance:

• Obstructing highway

• Selling unsafe food

• Keeping explosives near public road

• Operating a brothel or illegal gaming house (historically)

Requirement for individual civil action for public nuisance: Claimant must prove special damage beyond that suffered by general public (e.g., blocked road causes specific business loss not shared by all).

PART 6: DEFAMATION

6.1 Definition and Elements

Definition: A tort that protects reputation by allowing claim for false statements that harm a person’s standing in the community.

Elements (common law – varies slightly by jurisdiction):

6.2 Libel vs. Slander

6.3 Defences to Defamation

Case (New York Times Co. v Sullivan, 1964 – US constitutional defamation – not common law but influential): Public official cannot recover for defamation absent actual malice (knowledge of falsity or reckless disregard for truth). Not followed in most common law jurisdictions (UK, Canada, Australia) but influenced common law’s development of “Reynolds privilege” for responsible journalism (UK).

PART 7: ECONOMIC TORTS

7.1 Passing Off

Definition: A tort that protects goodwill of a business by preventing a defendant from misrepresenting their goods or services as those of the claimant.

Elements (classic trinity – from Erven Warnink v Townend, 1979 – UK):

Example (passing off – Coca-Cola v competitors): If a competitor sells cola in a red can with white script lettering similar to Coca-Cola’s distinctive trade dress, consumers may be confused → passing off.

Jif Lemon case (Reckitt & Colman v Borden, 1990 – UK): Jif lemon juice in yellow plastic lemon-shaped container. Competitor also sold lemon juice in similar yellow lemon-shaped container. Held: passing off (customer confusion “get-up”).

7.2 Inducing Breach of Contract

Definition: Tort committed when a third party intentionally and without lawful justification induces a person to breach their contract with the claimant.

Elements:

Example: Company A offers employment to key employee of Company B, knowing employee’s contract contains non-compete clause. Employee resigns in breach, joins Company A. Company A may be liable for inducing breach of contract.

Defence:

• Justification (e.g., legitimate competition, protection of equal or superior right)

7.3 Conspiracy

Definition: Two or more persons combine to cause damage to the claimant (lawful means or unlawful means conspiracy).

Difficult to prove – requires predominant purpose of causing damage (not merely advancing own interests).

PART 8: VICARIOUS LIABILITY

8.1 Definition and Rationale

Definition: A person or entity (employer) is held liable for torts committed by another (employee) within the scope of employment – even if employer is personally blameless.

Rationale:

• Employer has deeper pockets (can absorb loss, insured)

• Employer controls employee’s activities

• Employer benefits from employee’s work (risk should be allocated to beneficiary)

• Deterrence (employer will take precautions)

8.2 Elements of Vicarious Liability

Scope of employment – leading case (Salmond test, refined):

Case (Lister v Hesley Hall, 2001 – UK): Warden at boarding school sexually abused students. Held: vicarious liability – the acts were closely connected with the employment (relationship of trust, duty of care, treatment of children). Expanded scope beyond old “authorized act” test to “close connection” test.

Case (Bazley v Curry, 1999 – Canada, Supreme Court): Similar facts (non-profit child care – employee sexually abused children). Held: vicarious liability for intentional criminal acts if they are materially related to risks authorized by the enterprise.

Independent contractors: Generally no vicarious liability (principal not liable for contractor’s torts) – exceptions:

• Non-delegable duties (employer cannot delegate certain duties – e.g., duty to provide safe workplace)

• Ultra-hazardous activities

• Apparent agency (if contractor appears to be employee, e.g., branded delivery van)

8.3 Employer’s Direct Liability

Separate from vicarious liability – employer may be directly negligent:

• Hiring (negligent hiring – employing person known to be dangerous)

• Training (inadequate training)

• Supervision (failure to supervise)

• Equipment (failure to provide safe equipment or safe system of work)

PART 9: REMEDIES IN TORT

9.1 Damages (Compensatory)

Principle: Restore claimant to position before tort (as far as money can).

Types of damages:

Categories of general damages (personal injury):

• Pain and suffering

• Loss of amenity (loss of ability to enjoy activities)

• Loss of expectation of life

• Future care costs

• Loss of future earning capacity (lump sum calculated via multiplier).

9.2 Punitive (Exemplary) Damages

Purpose: Punish defendant, deter others (not compensatory).

Exceptions: Not generally available in tort – only permitted in limited circumstances (jurisdiction-specific):

• Oppressive, arbitrary, or unconstitutional conduct by government

• Conduct calculated to yield profit exceeding compensatory damages

• Usually requires malice or reckless disregard.

Case (Rookes v Barnard, 1964 – UK): Established limited categories for exemplary damages. But subsequent UK case law has reduced availability.

9.3 Injunctions

Definition: Court order requiring defendant to do something (mandatory injunction) or refrain from doing something (prohibitory injunction).

Use in tort: Particularly in nuisance, passing off, trespass (where damages inadequate).

Requirements for interlocutory (pre-trial) injunction:

9.4 Self-Help (Non-judicial)

Limited circumstances where claimant may use reasonable force to:

• Eject trespasser (after request to leave refused)

• Abate nuisance (enter neighbor’s land to remove nuisance – normally require notice)

Warning: Self-help is risky – if mistaken, claimant may be liable for trespass. Courts prefer judicial remedies.

9.5 Limitation Periods

LAW-1203: Criminal Law – Complete Study Notes

Course Overview

Criminal Law is the body of law that defines conduct prohibited by the state because it threatens or harms public safety and welfare, and establishes punishment for such conduct. Unlike civil law (which resolves disputes between private parties), criminal law involves the state prosecuting an individual for violating a public duty.

Core Questions:

• What makes an act a crime?

• When is a person legally responsible for their actions?

• What defenses excuse or justify otherwise criminal conduct?

Primary Legislation in Pakistan: Pakistan Penal Code (PPC), 1860 (Act XLV of 1860) 

PART 1: NATURE AND SCOPE OF CRIMINAL LAW

1.1 Definition of a Crime

A crime is an act or omission that:

1. Is prohibited by law (statute or common law)

2. Is considered harmful to society as a whole (not just an individual)

3. Is punishable by the state through imprisonment, fine, or other sanction

Pakistan Penal Code Definition: Section 40 of the PPC defines an “offence” as any act or omission made punishable by any law for the time being in force .

1.2 Criminal Law vs. Civil Law

Criminal law represents public opinion and moral values, enforces social control, deters criminal behavior, punishes transgressors, and banishes private retribution .

1.3 Classification of Offences (Pakistan) 

At the time of commission, offences are divided into cognizable and non-cognizable:

At the time of arrest, offences are classified as bailable or non-bailable:

At the time of compromise, offences are compoundable or non-compoundable:

1.4 Classification of Offences (Common Law) 

PART 2: GENERAL PRINCIPLES OF CRIMINAL LIABILITY

2.1 The Fundamental Principle: Actus Non Facit Reum Nisi Mens Sit Rea

The Latin maxim means: “An act does not make a person guilty unless the mind is also guilty.”

Every crime has two essential components :

CRIME = ACTUS REUS (guilty act) + MENS REA (guilty mind)

ACTUS REUS + MENS REA = CRIMINAL LIABILITY

2.2 Actus Reus (The Guilty Act)

Definition: The physical or external element of a crime – the voluntary act or omission that causes harm .

Forms of Actus Reus:

Requirements for a Valid Act:

Liability for Omissions:

A person is generally not liable for failing to act unless they are under a legal duty to act. Legal duties may arise from :

Causation:

For result crimes (e.g., homicide), the prosecution must prove that the defendant’s act caused the prohibited result .

Key Rule: The event would not have happened the same way without the direct participation of the offender .

2.3 Mens Rea (The Guilty Mind)

Definition: The mental element of a crime – the state of mind required for liability. Mens rea is “the rule of, rather than the exception to, the principles of Anglo-American criminal jurisprudence” .

Hierarchy of Mental States (Model Penal Code & Common Law) :

Most crimes require purpose, knowledge, or recklessness. Negligence is sufficient only when the crime definition specifically includes it .

Intention (Direct and Indirect/Oblique):

Recklessness:

2.4 Correspondence Principle

The correspondence principle requires that the mens rea for each element of the actus reus must correspond – the mental state must relate to the physical act .

Example – Murder: Actus reus = causing death; Mens rea = intention to kill or cause grievous bodily harm → correspondence satisfied.

Violation: Attempt crimes where D intends lesser harm but greater harm results – courts may still convict of attempted greater harm if intention corresponds.

2.5 Coincidence of Actus Reus and Mens Rea

For criminal liability, the actus reus and mens rea must occur at the same time. However, courts treat continuing acts flexibly – if D forms intent at any point during a continuing act, coincidence is satisfied.

Example – Continuing act theory: D hits V (no intent); later decides to kill V while V is still unconscious from first blow; D’s continuing assault includes the moment intent was formed.

2.6 Transferred Malice

If D intends to harm A but accidentally harms B instead, the malice (intent) transfers from A to B. D is liable for the crime against B as if B had been the intended victim.

Example: D shoots at A but misses and kills B → D is liable for murder of B (transferred malice).

Limitation: Malice only transfers between crimes of the same type. Cannot transfer intent to kill (murder) to intent to damage property (criminal damage).

2.7 Ignorance and Mistake

The doctrine that ignorance of law is not a defense is supported by the proposition that criminal acts may be recognized as harmful and immoral by any reasonable adult .

PART 3: STRICT LIABILITY

3.1 Definition

Strict liability offences are crimes that do not require proof of mens rea for at least one element of the actus reus. The prosecution need only prove the defendant voluntarily committed the prohibited act .

3.2 Rationale

The rationale for eliminating the mens rea requirement is that requiring proof of intent or even negligence would render regulatory legislation largely ineffective and unenforceable .

3.3 Categories of Strict Liability Offences

Pakistan Context: Under PPC, certain offences impose liability without requiring full mens rea where public interest is concerned.

3.4 Criticisms of Strict Liability

PART 4: PARTIES TO A CRIME

4.1 Classification of Participants (Common Law Tradition) 

4.2 Joint Liability (Common Intention) – Section 34 PPC

Section 34, Pakistan Penal Code: “When a criminal act is done by several persons in furtherance of the common intention of all, each of such persons is liable for that act in the same manner as if it were done by him alone.”

Requirements for Section 34:

1. Criminal act done by several persons

2. Common intention among all participants (pre-arranged plan)

3. Act done in furtherance of that common intention

Key Point: Mere presence at crime scene is insufficient. However, presence plus encouragement or shared mental state may establish common intention.

4.3 Abetment – Sections 107-109 PPC

Section 107: A person abets the doing of a thing who:

Punishment: Section 109 PPC – abettor punished with same punishment as for original offence.

PART 5: INCHOATE OFFENCES (Incomplete Crimes)

These are crimes committed before the full offence is completed. The law punishes inchoate offences to intervene early.

5.1 Attempt

Definition: D does an act that is more than merely preparatory to the commission of an offence, with intent to commit the full offence.

Actus reus of attempt: Act that is more than preparatory (objective test)

Mens rea of attempt: Intention to commit the full offence (even if full offence can be committed recklessly or negligently, attempt requires intention)

Impossibility: Legal impossibility (where the completed act would not be a crime) is defense. Factual impossibility (where circumstances prevent completion) is not a defense.

Example – Factual impossibility: D puts hand in empty pocket intending to steal; if pocket is empty → still guilty of attempt to steal.

5.2 Conspiracy

Definition: Agreement between two or more persons to commit an unlawful act (or lawful act by unlawful means).

Actus reus: Agreement (no overt act required in many jurisdictions)

Mens rea: Intention to agree AND intention to carry out the unlawful purpose

Pakistan: Conspiracy is also a mode of abetment under Section 107 PPC. Once agreement is made and act done in pursuance, all co-conspirators liable.

5.3 Solicitation/Incitement

Definition: Encouraging, requesting, or commanding another person to commit an offence, with the intent that the offence be committed.

Actus reus: Communication (words, letter, gesture) – need not reach intended person

Mens rea: Intent that offence be committed

Pakistan: Addressed through abetment by instigation (Section 107 PPC)

PART 6: GENERAL DEFENCES

Defences operate to excuse (defendant not blameworthy) or justify (act was right in circumstances) what would otherwise be criminal conduct.

6.1 Lack of Capacity Defences

Insanity (Mental Disorder)

M’Naghten Rules (1843) – the traditional common law test :

A person is not criminally responsible if, at the time of the act:

“He did not know the nature and quality of his act, or if he did know it, he did not know that what he was doing was wrong.”

Two limbs of M’Naghten:

1. Cognitive limb (nature/quality) – Did D understand what they were physically doing? (e.g., cutting throat)

2. Wrongfulness limb – Did D know the act was wrong (legally/morally)?

Model Penal Code approach (broader) – adopted in many US jurisdictions:

A person is not responsible if “as a result of mental disease or defect he lacks substantial capacity either to appreciate the criminality of his conduct or to conform his conduct to the requirements of the law” .

Pakistan Position: Insanity is recognized as a defense under PPC. Insanity at time of trial leads to special finding; accused may be detained in mental health facility.

Intoxication

General Rule: Voluntary intoxication (self-induced) is not a defense, though it may negate specific intent where such intent is required .

Pakistan: Intoxication is not generally recognized as mental incapacity. Being drunk may be an aggravating circumstance rather than a defense .

Age (Infancy)

6.2 Justification Defences

Self-Defence (Section 96-105 PPC)

General Principle: A person may use reasonable force to defend themselves or others from imminent harm .

Requirements:

Right of private defence of body extends to causing death only if there is reasonable apprehension of:

• Death

• Grievous hurt

• Rape

• Gang rape

• Kidnapping

Right of private defence of property extends to causing death only for:

• Robbery

• House-breaking by night

• Arson of dwelling house

• Theft or mischief causing reasonable apprehension of death or grievous hurt

Necessity (Sections 80-81 PPC)

Definition: Person compelled by natural forces to choose between evils may engage in otherwise criminal conduct .

Leading English Case – R v Dudley and Stephens (1884): Shipwrecked sailors killed and ate cabin boy to survive. Court rejected necessity defense for homicide. The court recognized such circumstances of necessity might constitute defense only if those sacrificed fairly selected (e.g., by lot) .

Pakistan’s Position: Section 81 PPC provides that an act done without criminal intention to cause harm and in good faith to avert other harm is not an offence . However, this does not categorically extend to homicide.

Duress (Coercion)

Definition: D commits crime because of threat of death or serious bodily harm from another person.

Requirements:

• Threat of death or serious injury

• Immediate/ imminent

• Person of ordinary firmness would have complied

• Not self-induced

Limitation: Duress is generally not a defense to murder.

6.3 Other Defences

Consent

General Rule: Consent is not a defense to serious offences against the person. Cannot consent to death or grievous hurt (limited exceptions: medical procedures, sports).

Entrapment

Definition: Government agent induces D to commit crime D was not otherwise predisposed to commit.

Rationale: Courts may exclude evidence or dismiss charges to deter police misconduct. Not a true substantive defense.

PART 7: THE PAKISTAN PENAL CODE (PPC), 1860 – OVERVIEW

7.1 Structure of the PPC 

7.2 Qisas and Diyat (Chapter XVI) 

Qisas (Retribution): The principle of “eye for an eye” – the victim or family may demand equivalent punishment.

Diyat (Blood Money): Financial compensation paid to victim or family in lieu of qisas.

Key Sections:

• Section 337 B – Jurh (wound or hurt not amounting to life-threatening)

• Section 337 C – Jaifah (wound penetrating body cavity)

• Section 337 F – Punishment for hurt by rash or negligent driving

• Section 338 – Isqat-i-haml (miscarriage)

• Section 338 B – Isqat-i-janin (causing death of unborn child)

7.3 Key Definitions from PPC 

PART 8: SPECIFIC OFFENCES (OVERVIEW)

8.1 Homicide

8.2 Hurt (Tashih-e-udw) 

8.3 Offences Against Property

8.4 Offences Against the Person (Non-fatal)

8.5 Sexual Offences

*Note: Specific sexual offence provisions evolve with legislative amendments (e.g., Anti-Rape Laws 2021, Protection of Women Against Violence Acts).*

8.6 Offences Against the State

PART 9: PROCEDURAL CONTEXT

9.1 The Criminal Justice Process

9.2 Standard of Proof

The prosecution must prove the defendant’s guilt beyond reasonable doubt. This is the highest standard in law, reflecting the seriousness of criminal conviction and the power of the state.

If the jury or judge has any reasonable doubt, the accused must be acquitted. The accused does not need to prove innocence; burden is on prosecution throughout, and the accused is presumed innocent unless and until proven guilty.

LAW-2115 Law of Contract – Comprehensive Study Notes

Part 1: Introduction to Contract Law

1.1 Definition and Nature of Contract Law

What is a Contract?
Section 2(h) of the Contract Act, 1872 defines a contract as: “An agreement enforceable by law is a contract.” 

This definition establishes two essential requirements:

1. There must be an agreement (offer + acceptance)

2. The agreement must be enforceable by law (legally binding)

Agreement vs. Contract:

• Agreement (Section 2(e)): “Every promise and every set of promises, forming the consideration for each other.”

• Contract: Agreement + Legal enforceability 

Promise (Section 2(b)): “A proposal when accepted becomes a promise.”

1.2 Sources of Contract Law in Pakistan

The primary source is The Contract Act, 1872 (Act No. 9 of 1872), which came into force on September 1, 1872. This is a pre-partition statute that continues to govern contracts in Pakistan. 

Key Features of the Contract Act, 1872:

• It is not a complete code but covers essential principles

• Based on English common law principles adapted to Indian/Pakistani conditions

• Applies to all types of contracts unless specifically excluded

• Principles of English law (Chitty on Contracts, Anson, Cheshire & Fifoot) are persuasive authority 

Other Related Laws:

• The Specific Relief Act, 1877: Provides remedies like specific performance, injunctions 

• The Sale of Goods Act, 1930: Governs contracts for sale of goods

• The Partnership Act, 1932: Governs partnership agreements 

• The Negotiable Instruments Act, 1881: Governs cheques, bills of exchange, promissory notes

1.3 Islamic Perspective on Contracts

The Council of Islamic Ideology Pakistan has emphasized that contractual relationships should be based on Islamic principles including mutual consent, fairness, and justice. 

Key Islamic Contract Principles:

• Sighah (offer and acceptance) is identical to agreement concept

• Free consent is integral to Sighah (unlike Contract Act where it is separate)

• Contracting parties must be competent to understand risk and liability

• Impediments to capacity include: minority, lunacy, insanity, death illness, insolvency, coercion, forgetfulness 

• Invitation to treat is not recognized in Islamic law (auctions are exception) 

Part 2: Classification of Contracts

2.1 Types of Contracts

2.2 Distinction Between Void, Voidable, and Void Ab Initio

Part 3: Essential Elements of a Valid Contract (Section 10)

Section 10 of the Contract Act, 1872 states: “All agreements are contracts if they are made by the free consent of parties competent to contract, for a lawful consideration and with a lawful object, and are not hereby expressly declared to be void.”

3.1 The Six Essential Elements

3.2 Offer (Proposal) – Sections 2(a), 4-9

Definition (Section 2(a)) : “When one person signifies to another his willingness to do or to abstain from doing anything, with a view to obtaining the assent of that other to such act or abstinence, he is said to make a proposal.”

Essentials of a Valid Offer:

1. Must be communicated to the offeree (Section 4)

2. Must show willingness to create legal relations

3. Terms must be definite and certain

4. May be express or implied (Section 9)

5. May be general (to public at large) or specific

6. Must be distinguished from invitation to treat

Invitation to Treat vs. Offer:

Communication of Offer (Section 4) : The communication of a proposal is complete when it comes to the knowledge of the person to whom it is made.

Revocation of Offer (Section 6) : An offer may be revoked:

• Before communication is complete

• Before acceptance

• By notice of revocation

• By lapse of prescribed time (or reasonable time)

• By failure of condition

• By death or insanity before acceptance

• By counter-offer (rejection)

3.3 Acceptance – Sections 2(b), 4-9

Definition (Section 2(b)) : “When the person to whom the proposal is made signifies his assent thereto, the proposal is said to be accepted. A proposal, when accepted, becomes a promise.”

Essentials of Valid Acceptance:

1. Must be absolute and unqualified (Section 7(1))

2. Must be communicated to the offeror (Section 4)

3. Must be in prescribed manner (Section 7(2))

4. Must be given within reasonable time

3.4 Consideration – Sections 2(d), 23, 25

Definition (Section 2(d)) : “When at the desire of the promisor, the promisee or any other person has done or abstained from doing, or does or abstains from doing, or promises to do or abstain from doing, something, such act or abstinence or promise is called a consideration for the promise.”

Essentials of Consideration:

1. Must move at the desire of the promisor

2. May move from promisee or any other person (privity exception)

3. May be past, present, or future

4. Need not be adequate but must be of some value

5. Must be real and not illusory

1. Natural love and affection (written, registered)

2. Past voluntary service

3. Time-barred debt (written promise)

4. Agency creation (Section 185)

5. Gift (completed, no consideration required)

Section 11: “Every person is competent to contract who is of the age of majority according to the law to which he is subject, and who is of sound mind, and is not disqualified from contracting by any law to which he is subject.”

Three Categories of Persons Incompetent to Contract:

Minor’s Contract (Critical Appraisal):

• Privy Council in Mohori Bibee v. Dharmodas Ghose (1903): Minor’s contract is void ab initio 

• No ratification on attaining majority

• Minor cannot be compelled to perform

• Doctrine of restitution not applicable against minor

• Minor can be promisee (enforce contract against adult)

• Minor’s liability for necessaries: Section 68 (liable from estate, not personally) 

Person of Unsound Mind (Section 12):

• Sound mind: capable of understanding contract and forming rational judgment

• Unsound at time of contracting: contract void

• Lucid intervals: valid contract

• Types: Idiots, lunatics, drunken persons

3.6 Free Consent – Sections 13-22

Definition (Section 13) : “Two or more persons are said to consent when they agree upon the same thing in the same sense.”

Free Consent (Section 14) : Consent is free when not caused by:

1. Coercion (Section 15)

2. Undue Influence (Section 16)

3. Fraud (Section 17)

4. Misrepresentation (Section 18)

5. Mistake (Sections 20, 21, 22)
