, rooted in English legal tradition, forms the basis of many modern legal systems. It relies on judicial decisions and precedents to shape legal principles, evolving over time to address new challenges and societal changes.

Unlike systems based on codified statutes, common law adapts through case-by-case rulings. This flexibility allows for nuanced interpretations, but can also lead to complexity and varying outcomes across jurisdictions.

Origins of common law

  • Developed in England after the Norman Conquest in 1066
  • Evolved through decisions of courts and similar tribunals rather than through legislative statutes or executive actions
  • Initially based on custom and precedent rather than written laws

Top images from around the web for Stare decisis vs judicial precedent
  • is the legal principle of determining points in litigation according to precedent
  • refers to the process of judges making decisions based on previous court rulings in similar cases
  • Lower courts are bound by the decisions of higher courts within the same jurisdiction
  • Precedents can be overturned by a higher court or legislature, but this is relatively rare

Sources of common law

Case law vs legislation

  • consists of the legal principles and rules derived from judicial decisions, as opposed to statutes or constitutions
  • refers to laws enacted by a legislative body, such as a parliament or congress
  • In common law systems, case law is the primary source of law, while legislation plays a secondary role
  • Case law can interpret and apply legislation, but cannot override it

Common law reasoning

Analogical vs deductive reasoning

  • involves drawing similarities between cases and applying the legal principles from one case to another
  • starts with a general legal principle and applies it to a specific case
  • Common law relies heavily on analogical reasoning, as judges seek to apply established legal principles to new situations

Distinguishing vs overruling precedent

  • Distinguishing a precedent means finding a significant difference between the current case and the precedent, allowing the court to reach a different decision
  • Overruling a precedent means that a higher court declares a previous decision to be invalid and no longer binding
  • Distinguishing is more common than overruling, as it allows judges to adapt the law to new circumstances without completely rejecting established principles

Equity in common law

Role of equity vs common law

  • is a body of law that developed alongside common law to provide remedies where common law was inadequate or inflexible
  • Equity is based on principles of fairness and justice, rather than strict legal rules
  • Equity can provide remedies such as injunctions, , and , which are not available under common law
  • In modern common law systems, equity and common law have largely merged, but some distinctions remain

UK vs US common law

  • The United Kingdom and the United States both have common law legal systems, but there are some differences
  • The UK has a unitary legal system, while the US has a federal system with both federal and state courts

  • The US has a that limits the power of the legislature and protects individual rights

Civil law vs common law systems

Key differences in sources of law

  • Civil law systems are based primarily on written codes and statutes, while common law systems rely more on case law and precedent
  • In civil law systems, the primary source of law is legislation, while in common law systems, it is case law
  • Civil law systems have a more rigid and structured approach to legal reasoning, while common law systems allow for more flexibility and adaptation

Role of judges vs legislators

  • In civil law systems, judges are seen as interpreters of the law, while in common law systems, they are seen as creators of law through their decisions
  • In civil law systems, the legislature is the primary lawmaking body, while in common law systems, judges play a more active role in shaping the law
  • Civil law judges tend to be more specialized and have less discretion than common law judges

Advantages of common law

Flexibility vs predictability

  • Common law is more flexible than civil law, as it can adapt to changing circumstances through the development of new legal principles
  • This flexibility allows common law to evolve over time and respond to new social and technological developments
  • However, the flexibility of common law can also lead to less predictability, as the outcome of a case may depend on the specific facts and the interpretation of the judge

Disadvantages of common law

Complexity vs accessibility

  • Common law can be more complex than civil law, as it relies on a large body of case law and legal principles that may not be easily accessible to non-lawyers
  • The complexity of common law can make it difficult for individuals to understand their legal rights and obligations
  • Common law systems may require more legal expertise and resources to navigate than civil law systems

Modern developments in common law

Influence of statutes vs case law

  • In recent years, there has been a trend towards greater use of legislation in common law systems, as governments seek to address social and economic issues through statutory reform
  • However, case law remains an important source of law in common law systems, particularly in areas where legislation is absent or unclear
  • The balance between statutes and case law varies between different common law jurisdictions and areas of law

Harmonization with civil law systems

  • There has been a movement towards greater harmonization between common law and civil law systems, particularly in areas such as international trade and human rights law
  • This harmonization has been facilitated by the development of international legal instruments, such as treaties and conventions, that seek to establish common legal principles across different legal systems
  • However, significant differences remain between common law and civil law systems, and complete harmonization is unlikely in the near future

Key Terms to Review (24)

Analogical reasoning: Analogical reasoning is a cognitive process that involves drawing comparisons between two similar situations or concepts to infer conclusions or principles applicable to a new context. This method is particularly important in the legal field, as it allows legal professionals to apply established legal precedents to new cases by highlighting similarities, ensuring consistency and predictability in the application of the law.
Barrister: A barrister is a legal professional in common law jurisdictions who specializes in representing clients in court and providing expert legal advice. They are typically distinguished from solicitors, as barristers are often called upon to advocate in higher courts, where they present cases and cross-examine witnesses. Their expertise in court procedures and legal arguments makes them essential to the adversarial legal system.
Case Law: Case law refers to the body of law that is established through judicial decisions in court cases. This form of law is created when judges interpret and apply statutes or constitutional provisions to specific situations, leading to precedents that guide future decisions. Understanding case law is crucial as it influences both common and statutory law, and highlights the role of judicial interpretation in shaping legal outcomes.
Civil Law: Civil law refers to a branch of law that deals with the rights and obligations of individuals and organizations in non-criminal matters. It primarily focuses on resolving disputes between private parties through compensation or specific performance rather than punishment. This legal framework is distinct from criminal law and emphasizes the importance of written codes and statutes, which provide clear guidelines for legal proceedings.
Common law: Common law is a legal system that is based on judicial decisions and precedents rather than statutes or written laws. It evolved in England and is characterized by the principle of stare decisis, which means that courts are bound to follow the decisions made in previous cases. This system allows for flexibility and adaptability as it develops over time through the interpretation of judges, and it plays a crucial role in various aspects of law, including property rights and personal property.
Common law jurisdiction: Common law jurisdiction refers to a legal system that is primarily based on court decisions and judicial precedents rather than solely on statutory laws. This system allows for the evolution of law through the outcomes of individual cases, making it adaptable to new situations as they arise. In such jurisdictions, judges play a critical role in interpreting the law and setting precedents that guide future cases, thus ensuring consistency and stability in the legal framework.
Court Hierarchy: Court hierarchy refers to the structured organization of courts within a legal system, where courts are ranked according to their jurisdiction and authority. This system allows for a clear path of appeal, ensuring that higher courts can review and potentially overturn decisions made by lower courts, thereby promoting consistency and fairness in the legal process.
Deductive Reasoning: Deductive reasoning is a logical process where conclusions are drawn from a set of premises or facts, moving from the general to the specific. It relies on the structure of arguments to establish validity, ensuring that if the premises are true, the conclusion must also be true. This type of reasoning is essential in various fields, particularly in law, where establishing precedents and applying them to specific cases is crucial for sound legal decision-making.
Distinguishing Precedent: Distinguishing precedent is a legal principle that allows a court to decide a case based on its unique facts rather than being bound by previous rulings. This concept is crucial in common law, where courts often rely on past decisions, known as precedents, to guide their judgments. When courts distinguish a precedent, they acknowledge that while the previous case may have similar elements, the differences in facts justify a different legal outcome.
Equity: Equity is a branch of law that aims to provide justice and fairness when the strict application of common law may result in an unjust outcome. It originated in the English legal system as a response to the limitations and rigidity of common law, allowing for more flexible remedies, such as injunctions or specific performance, rather than solely monetary damages. This branch focuses on principles of fairness and moral rights, often filling the gaps where traditional legal rules fall short.
Injunction: An injunction is a legal order issued by a court that requires a person to do or refrain from doing specific acts. This type of court order serves as a remedy to prevent harm or to maintain the status quo until a final decision is made. Injunctions can be temporary or permanent and play a crucial role in addressing disputes, especially in contexts where monetary damages may not be sufficient to resolve the issue at hand.
Judicial Precedent: Judicial precedent refers to the legal principle where past court decisions are used as a reference for deciding future cases. This system relies on the doctrine of stare decisis, which means 'to stand by things decided,' ensuring that similar cases yield consistent rulings and uphold the rule of law. By following established precedents, courts create stability and predictability in the legal system, allowing individuals and entities to understand their rights and obligations under the law.
Legislation: Legislation refers to the process of making or enacting laws, often initiated by a legislative body, such as a parliament or congress. This process is crucial for establishing rules that govern society and can significantly influence legal principles, including those derived from common law. Legislative acts provide formal authority and can either create new laws or amend existing ones, ultimately shaping the legal landscape.
Negligence: Negligence is a legal concept that refers to the failure to exercise the level of care that a reasonable person would in similar circumstances, leading to unintended harm to another party. This concept is central to tort law and often revolves around the idea of duty of care, breach of that duty, causation, and damages. Understanding negligence helps clarify how responsibility is assigned when someone’s lack of proper care causes injury or loss.
Overruling Precedent: Overruling precedent is a legal concept where a higher court changes or overturns the decision made by a lower court or a previous ruling. This can happen when the higher court finds that the earlier decision was incorrect, either due to changes in law, societal values, or an evolution in understanding. The ability to overrule precedent is crucial for the adaptability and growth of the legal system, allowing it to reflect contemporary standards and ensure justice.
Parliamentary Sovereignty: Parliamentary sovereignty is a fundamental principle in the legal framework of the UK, asserting that Parliament has the supreme legal authority to create or end any law. This means that no other body, including courts or the executive, can override or set aside legislation passed by Parliament. It highlights the notion that Parliament is the ultimate source of law, emphasizing its role in a constitutional democracy.
Restitution: Restitution is a legal remedy aimed at restoring a party to the position they were in before a wrongful act occurred, primarily focusing on compensating for loss rather than punishment. This concept is deeply rooted in the principle of preventing unjust enrichment, ensuring that a person does not benefit at another's expense. It connects closely to the idea of fairness and equity in legal proceedings, serving as a crucial element in both common law and contract performance scenarios.
Solicitor: A solicitor is a type of lawyer in certain legal systems, particularly in the UK, who provides legal advice, prepares legal documents, and represents clients in lower courts. Solicitors typically have a more client-facing role, often working directly with individuals or businesses to handle legal matters like contracts, property transactions, and family law. Unlike barristers, solicitors generally do not appear in higher courts unless they have obtained additional qualifications.
Specific Performance: Specific performance is a legal remedy in contract law that compels a party to fulfill their contractual obligations as agreed upon, rather than providing monetary damages. This remedy is typically applied in cases where the subject matter of the contract is unique, such as real estate or rare goods, making it difficult to find an equivalent substitute. The remedy aims to ensure that the non-breaching party receives the benefit of their bargain as intended in the original agreement.
Stare decisis: Stare decisis is a legal principle that dictates courts should follow precedents established in previous cases when making rulings on similar matters. This principle promotes stability and predictability in the law, as it ensures that similar cases are treated consistently over time, thereby reinforcing the rule of law. By adhering to stare decisis, courts contribute to the development of a coherent legal framework and maintain the integrity of the judicial system.
Tort: A tort is a civil wrong that causes harm or loss to another person, leading to legal liability for the person who commits the tortious act. It covers a wide range of wrongful acts, from negligence to intentional infliction of emotional distress, and is primarily governed by common law principles. Understanding torts is essential as they form the basis for most personal injury claims and civil litigation, aiming to provide relief to victims and deter future wrongdoing.
UK Common Law: UK common law refers to the body of legal principles and precedents developed through court decisions in the United Kingdom, rather than through legislative statutes. It forms a crucial part of the legal system, emphasizing the importance of judicial decisions and case law in shaping legal outcomes. This system allows for flexibility and adaptability, as judges interpret laws based on prior rulings, which contributes to the consistency and predictability of legal proceedings.
US Common Law: US Common Law is a legal system that is based on judicial decisions and precedents rather than written statutes or regulations. This system emphasizes the role of court decisions in shaping the law, with judges interpreting and applying past rulings to present cases. Over time, it has developed through various sources including state laws, court rulings, and constitutional principles.
Written Constitution: A written constitution is a formal document that outlines the fundamental principles, structures, and rules of a political system. It serves as the supreme law of the land, providing a framework for governance and protecting the rights of citizens. This type of constitution is distinct from unwritten or customary forms, as it is codified and accessible, allowing for clear interpretation and enforcement.
