5. Law and Normative Systems

Key Concepts & Definitions

  • Law: An organized set of norms within a legal system.
  • Positive law: The body of laws and legal rules established, enacted, and in force within a state or geographic area at a given time.
  • Natural law: A set of universal, inherent moral principles of justice thought to apply to all humans independently of written legislation.

β˜… Must-know

πŸ“Œ Legal norms are distinguished from social, sports, fashion, moral, religious, and ethical norms by their source, authority, sanctions, and scope of application.

  • Legal norms are issued or applied by state institutions and courts and can carry fines or imprisonment, while religious norms draw authority from sacred texts and clergy, social norms from custom and etiquette, fashion norms from industry and media, and sports norms from governing bodies and referees.

Further detail

  • The official marathon distance is 42.195 km, adopted definitively in 1921 after the 1908 London Olympic race was extended to place its finish beneath the royal box.

Memory Hook

Legal norms carry state-backed penalties; social, religious, fashion, and sports norms operate within their own communities.

β˜… Must-know

  • The listed national-law sources and forms are:
    • legislation
    • constitutions
    • regulations
    • decrees and orders
    • contracts
    • custom
    • equity in common-law countries
    • legal doctrine

Further detail

  • French legislation is generally codified in codes, while legislation in the United Kingdom is not codified in the same way in the course’s comparison.

  • In common-law countries, equity may provide an injunction ordering a person to stop an action instead of merely awarding damages to the injured person.

  • International law includes international treaties as a type of legal norm.

7. Civil Law and Common Law

β˜… Must-know

  • Civil law primarily relies on codified statutes and written codes, whereas common law primarily relies on precedent and judicial decisions.

  • Civil-law reasoning is deductive, applying general abstract rules to particular cases, whereas common-law reasoning is inductive, extracting general principles from particular cases.

  • In civil-law systems, judges apply law to facts and act as investigators in an inquisitorial system, whereas common-law judges interpret law and set binding precedents within an adversarial system.

  • Common-law precedent is binding, so lower courts must follow higher-court rulings, whereas civil-law decisions are not strictly binding and instead provide persuasive guidance.

Further detail

  • Civil law is associated with Roman law and is predominant in continental Europe, Latin America, and parts of Asia and Africa, while common law originates in English law and is predominant in the United States, the United Kingdom, Canada, Australia, and former British colonies.

  • Both civil-law and common-law systems aim to maintain social order, resolve public and private disputes, enforce rights and obligations, recognize constitutional hierarchy, separate powers, and protect procedural fairness and the right to a defense.

Memory Hook

Civil law reasons from codes down to cases; common law builds principles upward from cases.

Key Concepts & Definitions

  • Mixed legal system: A combination of European civil law, including codified statutes and Roman-law origins, with Anglo-American common law, including judge-made law and precedent.

β˜… Must-know

πŸ“Œ In mixed jurisdictions, private matters such as contracts, property, family law, and successions are commonly governed by civilian codes, while constitutional, criminal, and administrative law and judicial procedure tend to follow common-law mechanisms.

Further detail

  • Louisiana combines French and Spanish colonial codes and Napoleonic Code influence in private law with U.S. federal constitutional law, state criminal law, and procedural rules.

  • The 1763 Treaty of Paris preserved French private law in Quebec, which later formally codified that tradition in the Civil Code of Quebec alongside Canadian constitutional, criminal, and administrative law.

  • Scotland combines Roman-law and continental roots with binding precedent and common-law commercial statutes, but has never enacted a single comprehensive Civil Code.

  • Examples of distinctive civilian concepts are:

    • Louisiana: usufruct
    • Louisiana: servitudes
    • Louisiana: obligations
    • Quebec: extra-contractual liability and civil obligations
    • Scotland: delict rather than tort

Memory Hook

Picture a jurisdiction with civilian private-law codes on one side and common-law public law and procedure on the other.

9. Historical Development of Common Law

β˜… Must-know

  • The course presents common law as initially judge-made law developed through royal courts and judicial decisions.

Further detail

  • The course identifies the U.S. Constitution of 1787, Marbury v. Madison (1804), and Brown v. Board of Education of Topeka (1954) as landmarks in U.S. constitutional and judicial history.

10. French Law and the Revolution

β˜… Must-know

πŸ“Œ Article 6 of the 1789 Declaration of the Rights of Man and of the Citizen states that law expresses the general will, citizens may participate personally or through representatives in its formation, and law must be the same for all whether it protects or punishes.

πŸ“Œ The statute of 16–24 August 1790 prohibited courts from participating in legislative power, making regulations, or interfering with administrative functions, and required judges seeking to interpret or create a law to refer the matter to the legislative body.

  • French law is presented as primarily written legislative law and codified through the Civil Code, while its judicial system is dual, including the Cour de cassation and the Conseil d’État.

Further detail

πŸ“Œ Article 4 of the 1789 Declaration of the Rights of Man and of the Citizen defines liberty as doing anything that does not harm others and permits legal limits only to secure the enjoyment of the same rights by others.

  • The course states that the 1790 separation of judicial and administrative functions gave rise to administrative tribunals and administrative law.

Memory Hook

The Revolution transfers lawmaking authority from the monarch to the general will, supporting legislation and codification.
