Sources of Legal Argumentation

Once you have identified your thesis and the topic of study, the next crucial step in crafting your legal essay is constructing a compelling legal argument with a solid structure. This process involves not just presenting opinions but engaging in a precise and formal debate supported by legal analysis and authorities. Legal arguments, unlike informal discussions, must adhere to strict rules and be built on credible sources. This article will explore how to form and assess legal arguments and ensure they are supported by the appropriate legal authorities.

The Nature of Legal Argumentation
At first glance, legal essay questions may seem to ask for an opinion, but they are not interested in personal views as one might express in casual conversation. Legal argumentation requires a structured approach that uses logical reasoning, case law, statutes, and academic commentary to construct and defend a position. The most effective way to learn how to organise legal arguments is to study court decisions, particularly those from higher courts such as the Supreme Court or the European Court of Human Rights. These decisions offer examples of how to approach difficult legal questions. Academic journals also provide valuable insights into the critical evaluation of legal disputes, offering deeper analysis beyond the standard textbook material. Legal arguments are built on sources, and the credibility of any argument is determined not just by its logical soundness but by the quality of the authorities supporting it. Whether you are identifying, critiquing, or defending a legal position, the origin of your argument is just as important as its content. In legal writing, the sources of authority you cite will often determine the strength of your argument.

Binding and Persuasive Authorities
In legal essay writing, there are two primary types of legal authorities: binding and persuasive. Both are crucial for constructing a robust legal argument.

1. Binding Authorities
Binding authorities form the foundation of any legal argument. These include statutes, regulations, and case law that establish what the law is. In legal essays, when presenting a rule or legal principle, you must be precise in attributing it to its source, whether it is a statute or judicial decision. An argument without a clear source is unsubstantiated. Similarly, quoting sources arbitrarily or without relevance to the topic weakens the argument. For instance, when discussing a specific legal principle, you should know its general application and any exceptions that may exist. Identifying and citing the relevant binding authority ensures that your argument is grounded in law. In problem-based legal questions, much of your argument will revolve around applying binding authorities to specific factual situations. However, in essay questions, the focus shifts slightly. You need to identify the key legal principles, but more attention is given to the second type of authority: persuasive authority.

2. Persuasive Authorities
Persuasive authorities are especially important when dealing with legal theory, reform, and critique. These are non-binding but can be highly influential in shaping legal debates. Public policy arguments, academic commentaries, and proposals for legislative reform all fall into this category. Public policy arguments are moral or political considerations that can influence legal decisions. They are often used to critique existing laws or advocate for reform. In essays, public policy can be a persuasive tool, but it must be handled carefully. For example, if you argue that a particular legal doctrine, such as constructive trust, discriminates against a certain group, you need to provide a clear rationale based on policy considerations. Moreover, understanding and engaging with opposing policy arguments is crucial to developing a well-rounded analysis. Academic writings, such as journal articles, are another valuable source of persuasive authority. These writings often offer critical evaluations of legal principles, and referencing them in your essay can demonstrate a deeper engagement with the topic. For example, citing an academic who supports or critiques a particular legal doctrine shows that you have engaged with expert perspectives. However, proper citation is essential, and failure to acknowledge the source can result in plagiarism. Citing dissenting opinions from court cases can also strengthen your argument. Disagreements in judicial reasoning often reveal the complexity of legal issues and can support alternative interpretations of the law. Documents such as Green and White Papers, draft bills, and Law Commission reports are excellent sources of persuasive authority, particularly when discussing legal reforms. They offer insights into potential changes in the law and can help frame your arguments about how the law should evolve. In some cases, comparing legal principles from other jurisdictions can provide persuasive arguments for legal reform in your jurisdiction. While English law remains distinct, other common law systems, or even civil law systems, can offer useful examples of how similar legal issues are handled elsewhere.

Combining Binding and Persuasive Authorities
A well-crafted legal essay must combine binding and persuasive authorities effectively. Binding authorities provide the legal foundation, while persuasive authorities allow you to critically engage with the law and propose reforms or alternative interpretations. Without a balance of both, your essay risks being either too rigid or too speculative. The most successful essays are those that use persuasive authorities to challenge or support binding legal principles thoughtfully.

Structure of Legal Argumentation
The structure of a legal essay is just as important as the argument itself. A clear, logical structure helps the reader follow your reasoning and ensures that your arguments are well-organised. While there is no single correct way to structure a legal essay, certain guidelines can help. One of the most common structures is the five-paragraph essay. This format includes an introduction that presents your thesis, three body paragraphs that explore your legal arguments, and a conclusion that summarises your findings. This structure is simple but effective, ensuring that each part of your argument is clearly presented. Another approach is the French method, which involves presenting an argument (thesis), counter-arguments (antithesis), and then resolving the tension between them (synthesis). This format is more complex but can be particularly useful for essays that require a nuanced analysis of competing viewpoints. For essays that focus on the development of a particular legal principle, a historical overview structure can be effective. This approach involves tracing the evolution of a legal concept over time, showing how it has been shaped by judicial decisions, statutes, and academic debate. Regardless of the structure you choose, the key is to ensure that your essay is cohesive and logically organised. Your thesis should guide the structure, and each part of the essay should contribute to the overall argument.

In legal writing, the sources of your argument are just as important as the argument itself. Binding authorities provide the legal foundation, while persuasive authorities allow you to critically engage with the law and suggest reforms or alternative interpretations. A well-structured legal essay combines both types of authority and presents them in a coherent, logical format that supports your thesis. If you understand the role of legal authorities and carefully structuring your argument, you can craft a compelling and persuasive legal essay.
