Types of Legal Research: Doctrinal, Non-Doctrinal, and More

Types of Legal Research: Legal research is an essential skill for law students, professionals, and scholars. Whether you are preparing for a case, drafting legal documents, or conducting academic work, understanding the different types of legal research can help you navigate the complexities of law. 

Legal research can be categorized into two primary types: doctrinal legal research and non-doctrinal legal research. Each of these methods serves a unique purpose and can be applied based on the nature of the legal problem at hand. Here, we will explore both of these types in detail, their characteristics, and how they contribute to the field of law.

Types of Legal Research

Legal research refers to the process of identifying and retrieving information necessary to support legal decision-making. This process typically involves searching for laws, case precedents, statutes, regulations, legal principles, and scholarly articles. 

Legal research serves various purposes, including the analysis of case law, understanding legislative intent, and providing arguments for or against specific legal positions.

The main objective of legal research is to ensure that a legal argument is backed by solid, authoritative sources. Legal research is not just about gathering information; it involves critically analyzing, comparing, and synthesizing legal texts to build persuasive arguments or informed opinions.

1. Doctrinal Legal Research: The Traditional Approach

Doctrinal legal research, also known as "black-letter" legal research, is the most traditional form of legal research. This approach is rooted in the examination and interpretation of legal texts, such as statutes, case law, regulations, and legal precedents. 

The primary objective of doctrinal legal research is to establish what the law is and to clarify the application of laws in specific cases.

Characteristics of Doctrinal Legal Research

• Focus on Legal Texts: Doctrinal research revolves around understanding and analyzing legal texts such as statutes, case law, legal codes, and judicial interpretations.
  
  

• Case Law Analysis: It extensively involves the study of case law, where the researcher examines court decisions to understand how laws are applied in real-life situations.
  
  

• Precedents and Authority: One of the core features of doctrinal research is its reliance on precedents. It follows the principle of stare decisis, meaning that court decisions in earlier cases are used as a guide for current and future legal issues.

• Interpretation of Statutes: Doctrinal researchers focus on the textual analysis of statutes and regulations to determine their meaning and implications in specific cases.

• Hypothesis Testing: This approach often involves formulating a hypothesis based on legal texts and then testing it through case law and other legal documents to draw conclusions.

When to Use Doctrinal Legal Research?

• Legal Analysis: Doctrinal research is ideal when you need to analyze the text of laws or regulations to understand their meaning and application.

• Litigation and Case Preparation: Lawyers often use doctrinal research when preparing for cases, especially when they need to refer to precedents and legal principles.

• Drafting Legal Documents: When drafting contracts, briefs, or legal opinions, doctrinal research ensures that the language and structure align with established legal norms.

Example of Doctrinal Research

Suppose a lawyer is preparing for a case involving breach of contract. They would conduct doctrinal legal research by reviewing previous court decisions related to contract breaches. They would analyze the reasoning behind court decisions, how the law was applied, and whether any precedents could influence the current case.

2. Non-Doctrinal Legal Research: The Empirical Approach

Non-doctrinal legal research, also known as socio-legal research or empirical legal research, focuses on understanding the real-world implications of law. This approach goes beyond the textual analysis of legal documents and examines the social, economic, political, and psychological factors that influence the law and its application. 

It is less concerned with theoretical analysis and more focused on practical outcomes.

Characteristics of Non-Doctrinal Legal Research

• Empirical Data Collection: Non-doctrinal research relies heavily on gathering data through surveys, interviews, case studies, and fieldwork. It involves observing how the law functions in real-life scenarios.

• Interdisciplinary Approach: It often incorporates elements from sociology, psychology, economics, and political science to understand the broader impact of legal principles on society.

• Law in Practice: Non-doctrinal research focuses on how laws are implemented and enforced in real-life settings. Researchers examine how people interact with the law and how legal systems influence behavior.
  
  

• Focus on Policy and Reform: This type of research is often used to evaluate the effectiveness of laws, propose legal reforms, or address issues of social justice.

When to Use Non-Doctrinal Legal Research?

• Policy Analysis and Reform: Non-doctrinal research is essential when studying the effectiveness of laws and proposing policy reforms. It is especially useful when you are interested in how laws affect individuals and communities.

• Law and Society: This research approach is used to explore the relationship between law and societal issues such as inequality, discrimination, or human rights.

• Understanding Legal Impact: Non-doctrinal research is useful when trying to understand the real-world consequences of legal decisions, especially in fields like criminal law, family law, or human rights.

Example of Non-Doctrinal Research

An example of non-doctrinal research would be studying the effectiveness of domestic violence laws in a specific region. A researcher may conduct interviews with victims, law enforcement officers, and legal professionals to understand how well the laws are working in practice, whether victims feel safe reporting abuse, and how enforcement can be improved. 

This empirical data helps to assess whether the current legal framework is sufficient or needs reform.

3. Comparative Legal Research: A Blend of Doctrinal and Non-Doctrinal Approaches

Comparative legal research is a hybrid research methodology that combines doctrinal and non-doctrinal research methods. This type of research focuses on comparing legal systems, doctrines, or practices from different jurisdictions. 

By examining similarities and differences between legal systems, comparative research can highlight the strengths and weaknesses of various legal approaches and offer insights into possible reforms.

Characteristics of Comparative Legal Research

• Comparison of Legal Systems: Comparative legal research examines how different legal systems address similar issues and identifies best practices or areas for improvement.

• Cross-Cultural Analysis: This research often involves comparing laws from different countries or regions, taking into account cultural, political, and economic contexts.

• Combination of Methods: Researchers combine doctrinal analysis of legal texts with empirical methods to gather data on how legal systems function in practice.

When to Use Comparative Legal Research?

• International Law: Comparative research is commonly used when studying international law, treaties, and conventions. It helps in understanding how different nations approach global legal issues.

• Cross-Jurisdictional Analysis: If you are studying the impact of legal reforms in different jurisdictions, comparative legal research provides valuable insights.

• Legal Harmonization: Comparative research is useful when seeking to harmonize laws across different jurisdictions, especially in the context of trade, human rights, or environmental law.
