What You'll Learn
Understanding the role of case law in civil and common law traditions
Case law, also used interchangeably with common law, is a law based on precedents set by judicial decisions from previous cases rather than law based on constitutions, statutes, or regulations. The doctrine of precedent developed during the 12th and 13th centuries as collective judicial decisions that were based on tradition, custom, and precedent. The form of reasoning used in common law is known as casuistry or case-based reasoning.
In the common law tradition, courts decide the law applicable to a case by interpreting statutes and applying precedents that record how and why prior cases have been decided. Common law systems follow the doctrine of stare decisis, by which most courts are bound by their own previous decisions in similar cases. According to stare decisis, all lower courts should make decisions consistent with the previous decisions of higher courts. For example, in England, the High Court and the Court of Appeals are each bound by their own previous decisions.
In civil law jurisdictions, the judiciary may not have the authority to invalidate legislative provisions. For instance, after the fall of the Soviet Union, the Armenian parliament, with support from USAID, adopted new legal codes that introduced problems that the judiciary was not empowered to address under the established principles of common law. There is no doctrine of stare decisis in the French civil law tradition, and courts lack the authority to act without a statute.
In common law countries, case law is used for judicial decisions of selected appellate courts, courts of first instance, agency tribunals, and other bodies discharging adjudicatory functions. Common law courts generally explain in detail the legal rationale behind their decisions, with citations of both legislation and previous relevant judgments, and often interpret the wider legal principles. The necessary analysis, called ratio decidendi, then constitutes a precedent binding on other courts.
In civil law jurisdictions, decisions are generally shorter, referring only to statutes. This is because these civil law jurisdictions adhere to a tradition that the reader should be able to deduce the logic from the decision and the statutes.

How to find cases on a particular topic
Finding case law on a particular topic can be done through various methods and tools. Here are some ways to approach it:
Using Databases and Online Tools
- Westlaw: This tool includes the West Key Number System, an index of American Law with a hierarchical structure of legal topics and assigned key numbers. It has been used by researchers to find cases by subject for over 100 years. On the homepage, select "Cases", then the jurisdiction, and click \"Advanced\" for more specific searches.
- Lexis Advance: Click \"Browse Topics\" at the top, then either use the search box or browse through the list of topics and sub-topics. You can also use the \"Search Topics\" box for a natural language or terms and connectors search.
- Bloomberg Law: This platform uses machine learning to identify legal principles, standards, and elements in court opinions. It identifies and matches legal statements based on language similarity and frequency.
- Manupatra: This website provides full-text decisions from the Indian Supreme Court, all High Courts, the Federal Court, and many tribunals. It covers judgments from the inception of each court and includes bare acts, amending acts, repealed legislation, and more.
- Indian Kanoon: This website contains unreported decisions and is more up-to-date than Manupatra or SCC Online.
- Queensland Legal Indices Online: This is a judgments indexing service that covers the Queensland Court of Appeal, Supreme Court, District Court, Planning and Environment Court, and other Queensland Tribunals.
- Fastcase or Casetext: These resources can be used if you do not have access to subscription-based case research tools.
Keyword and Natural Language Searching
- Construct a search string using keywords related to your topic. Avoid overly general terms and consider including alternative terms.
- Use natural language searching, similar to Google, by entering a string of keywords and letting the algorithm predict the relationship between terms.
- Utilise field searches to return highly relevant results. For example, searching for a phrase in a specific field, like a catchword field, will only retrieve cases where that phrase is present.
Other Strategies
- Reference Lists: Some legal encyclopedia entries in Lexis or Westlaw contain reference lists that may include pertinent topics and key numbers in the West Key Number System.
- American Law Reports: These reports contain in-depth articles on legal topics, each with its own table of contents, index, and research references. The Table of Cases breaks down relevant cases, statutes, and court rules across multiple jurisdictions.
- Case Notes and Annotations: Case annotations provide summaries of cases and how a particular statute has been applied by the courts. Case Notes are available on Lexis Advance, while Westlaw offers Notes of Decisions.
- Subsequent Citing Cases: Reading cases that have cited the case you've started with can help confirm that its legal conclusions remain sound. You can filter citing references by jurisdiction, date, keyword, and more.
- Legal Encyclopedias: These provide brief overviews of legal topics and may include case supplements that list relevant cases.
- Library Guides and Staff: University libraries often provide guides and assistance with legal research, including strategies for finding cases and brainstorming search strings.

How to analyse case law effectively
Case law is a crucial element of the legal system, providing guidance, consistency, and precedent for legal interpretations and rulings. It is a collection of reported cases that form the body of law within a given jurisdiction. Case law analysis is a fundamental aspect of the study of law, and an indispensable tool for law students to develop their analytical and critical thinking skills.
Understand the Core Issue
The core of case law analysis is figuring out the exact issue or issues the court is being asked to resolve, and the process by which the court resolved it. Essentially, you are looking for what the person who appealed the lower court's ruling wanted to happen, that didn't. To find the issue, you must determine what that person thought the lower court did wrong, and why. This is often not a simple or obvious error, and may involve arguing that the case in question is different from the cases that developed the rule.
Phrase the Issue as a Question
To understand the court's reasoning, phrase the issue as a yes/no question. This is the simplest way to approach the court's analysis of the legal issue. In some cases, there may be multiple yes/no questions, or follow-up questions that are conditional on the answer to the first. This often happens when a particular factual situation has never been explored by any other court.
Identify the Rules and Precedents
The rules used by the court to apply the law to a case's facts are usually precedents established by previous court decisions in similar cases. Make a note of the case from which the rule came, and consider whether you need to go back and read the previous case to understand the rule. If a significant portion of the opinion discusses the previous case, it is worth reading it to better understand the court's perspective.
Conduct Thorough Research
Read the case in question thoroughly, taking notes on key facts, legal issues, and arguments presented by both sides. Identify the key legal issues at play, and the relevant legal principles and precedents that may impact the case. This involves looking up statutes, regulations, and case law that apply to the facts of the case.
Develop Analytical Skills
By analyzing cases, you can improve your legal reasoning skills and develop a deeper understanding of the law. Legal case analysis tests your ability to identify key legal issues, apply legal principles to factual scenarios, and present persuasive arguments. It is a critical skill for success in the legal profession, helping attorneys advise clients and argue cases in court.

The interplay between case law and statutes
Case law, also used interchangeably with common law, is a law that is based on precedents, i.e., the judicial decisions from previous cases, rather than law based on constitutions, statutes, or regulations. Case law uses the detailed facts of a legal case that have been resolved by courts or similar tribunals. These past decisions are called "case law" or precedent. Stare decisis, a Latin phrase meaning "let the decision stand", is the principle by which judges are bound to such past decisions, drawing on established judicial authority to formulate their positions. These judicial interpretations are distinguished from statutory law, which are codes enacted by legislative bodies, and regulatory law, which are established by executive agencies based on statutes. In some jurisdictions, case law can be applied to ongoing adjudication, for example, in criminal proceedings or family law.
On the other hand, statutes can directly replace, modify, or give statutory effect to unwritten law, including judge-made law or common law. Statutes can also create new rights that sit alongside judge-made law, affecting the development of common law. Additionally, in civil law jurisdictions, decisions tend to be shorter, referring only to statutes, as these jurisdictions adhere to the tradition that the reader should deduce the logic from the decision and the statutes.
Furthermore, the relationship between case law and statutes involves analogical reasoning. Courts engage in analogical reasoning with respect to case law, and the question arises as to whether this reasoning can be applied to statutes as well. This question depends on how statutes are viewed within the common law system and their relationship with case law. While opinions recognizing statutes as sources of law that can be analogized and adapted to develop common law have not been overruled, there are questions about reconciling analogical reasoning with the constraints of the common law system.
In summary, the interplay between case law and statutes involves the interpretation of statutes by case law, the modification or replacement of case law by statutes, and the complex relationship between the two in terms of analogical reasoning. This interplay is essential to the functioning of the common law system and the development of the law.

The importance of case law
Case law is a crucial component of the legal system, providing guidance, consistency, and precedent for legal interpretations and rulings. It is a collection of reported cases that form the body of law within a given jurisdiction. Case law is developed by interpreting and applying existing laws to specific situations, thereby setting legal precedents that guide future rulings and interpretations.
Another advantage of case law is its ability to provide a detailed legal rationale for decisions. Common law courts, for instance, provide comprehensive explanations for their rulings, including citations of legislation and previous relevant judgments. This transparency enhances the understanding of the legal principles applied and allows for a more informed analysis of the decision. It also enables legal professionals and researchers to identify patterns, principles, and trends within the law, thereby facilitating a more nuanced understanding of the legal system.
Case law is particularly important in common law countries, such as the United Kingdom, United States, Canada, Australia, and others, where it plays a significant role in judicial decision-making. In these countries, courts interpret statutes and apply precedents from previous cases to determine the applicable law. This adherence to stare decisis, or the principle of respecting previous decisions, ensures consistency and predictability in the legal system.
Furthermore, case law is essential for understanding sentencing guidelines and how they are applied in practice. By examining case law, legal professionals can gain insights into the interpretation and application of sentencing guidelines, including departures from recommended sentences. This knowledge helps in predicting potential outcomes and understanding the rationale behind sentencing decisions.
In conclusion, the importance of case law lies in its ability to provide guidance, ensure consistency, and shape the evolution of the legal system. It offers clarity to legal professionals, contributes to a dynamic and responsive legal framework, and enhances the understanding of sentencing guidelines. By interpreting existing laws and setting precedents, case law plays a crucial role in the administration of justice and the development of the law.
