A master's thesis in law - how to build a legal analysis

In a law master's thesis, collecting provisions and judgments is only the beginning – you also need to explain how they answer your research question. Start with one uncertainty: for example, why courts read the same expression in a provision differently. Choose a period, check the relevant wording and read the reasons for the judgments. Then compare them with commentaries and articles: what does each court or author consider decisive, and why? This gives you the basis for your own reasoning rather than another series of summaries.

You can read dozens of judgments and still be unsure what to write. Often the missing element is a basis for comparison: you summarise successive cases without showing which shared uncertainty they help resolve. The same happens with commentaries. Collected scholarly opinions become analysis when you compare the arguments and explain why their differences matter.

I will show you how to turn that question into a chapter: find the provisions and judgments you need, take useful notes, compare explanations and write a conclusion. The examples concern academic research in Law.

Turn a broad topic into a legal research problem

“Reasons for administrative decisions” identifies an area, but covers many legal mechanisms, procedures and kinds of statement. Write down exactly what you want to establish. Are you interested in explanations of the legal basis, responses to a party's arguments, or differences in the interpretation of one concept? Your answer determines which provisions and judgments you need.

Narrowing a topic must preserve the substance of the disagreement. If the question could fit any thesis once you remove the institution's name, it is probably still too general. If it requires an examination of every branch of law, the scope is too broad.

Decide what you are actually studying

Distinguish analysis of legal content and interpretation from research into people's behaviour or institutional activity. A question about arguments supporting an interpretation requires legal texts, case law and scholarship. A question about how citizens understand official reasons also requires evidence about the readers. Judgments alone cannot answer that second question.

In the methodology, describe the steps you will actually take. You could explain that you will first check the provision's wording and its connections, then identify different readings in the judgments, and finally compare the reasons given by courts and authors. The label “doctrinal legal research” does not tell readers how you work. If you use earlier legislation or another legal system, explain what that comparison should clarify and which elements are comparable.

In “Methodology of Legal Research”, Agnieszka Bielska-Brodziak and Sławomir Tkacz distinguish, among other things, discovering an answer from justifying it. For thesis writing, this suggests a useful check: finding a position in a publication is a starting point. Your reader must also be able to see why you consider it convincing.

Specify the legal position and time frame

State both the period under examination and the date as at which you describe the law. These are different pieces of information. A judgment may concern an earlier version of a provision even if it was delivered or published later. Today's wording should not automatically be used to explain an older decision.

For every important enactment, check the official source, version, commencement dates and any amendments or transitional provisions relevant to your question. Record which version a commentary or judgment addresses. If you compare periods, explain whether you are examining a change in the text, a change in interpretation, or both. Mixing these levels makes the differences difficult to explain reliably.

Allow time for a final update check. A new publication or decision will not always require rewriting the thesis, but it may call for a qualification, a revised assessment or additional material. Base that decision on its relevance to your question instead of adding every newly available document.

Three kinds of source, three different functions

• Legal texts: let you check what the legislation says. Mark the expression your question concerns, then read the definitions and provisions it refers to. In your notes, explain whether and how they help you understand that expression.
• Judgments: show how a court explained its decision in a particular case. Note the dispute, the facts that mattered and how the court moved from the provision to the outcome. Also check the type of judgment and its significance within the legal system concerned.
• Academic literature: clarifies concepts and presents positions and criticism. A commentary author does not speak for the court, and a textbook statement does not replace checking the legislation.

Do not assess a source simply by asking whether it is “strong”. First establish its status and its purpose in that part of your argument. An article may explain the history of a disagreement well while predating a later amendment. A current news item may provide a search lead but will rarely provide enough material to reconstruct legal reasoning.

Use a search process you can explain

Start with the names of the legal mechanisms and concepts. Add synonyms, provision references and characteristic expressions found in the literature. Search official legislation and judgment databases alongside your university library's resources. A commercial legal information service may make this easier, but its results still need to be assessed.

Keep a search log recording the database, search date, query and inclusion criteria. Record exclusions too: decisions concerning different wording, documents without reasons, or cases addressing a different legal issue. Do not select only materials that confirm your first impression. A collection convenient for your thesis is not necessarily adequate for evaluating the disagreement fairly.

There is no universally correct number of judgments or books for a master's thesis. Adequacy depends on the question, the variety of positions and your stated scope. If few results appear, check your search language and access to older publications before deciding that the problem has not been discussed.

Extend the search through bibliographies and references in important publications. When a study is frequently cited, check which question later authors use it to address. Citation counts do not establish that a position is correct. They can help map a discussion and identify passages requiring closer reading. Keep separate lists of works you have read and works you still need to obtain. Do not present a publication known only from another bibliography as personally checked. If a key source remains unavailable, record the gap and assess whether you can fairly reconstruct the disagreement without it.

Read judgments for their reasoning

Read the full reasons where available. A search snippet or editorial headnote can help locate a document, but does not show the whole argument. Separate the parties' positions from the court's position. Record which question the court actually answered and which issues it did not need to decide.

Create a case note containing the court, date, case number, source, relevant circumstances, legislative version, issue, outcome, arguments and relevance to your research question. Add a page or section reference for later checking. You do not need to reproduce the full procedural history when only two circumstances explain the difference between the cases.

If two judgments seem contradictory, first check whether they are comparable. Different facts, a different procedural question or amended wording may explain the contrast. Only after that check should you consider whether there is an interpretative disagreement. One divergent statement is also insufficient to establish a lasting change in a line of case law.

Compare scholarly arguments rather than counting names

Create a note for one specific question, such as different readings of your chosen expression. For each author, record how they read it, which passage supports that reading and what objection they raise to another interpretation. Add the publication date, page and legislative version discussed. Mark quotations separately from your summaries, then add your own comment below. When you start writing, you will have answers to the same question side by side rather than a stack of book summaries.

Check that a difference between authors is substantive. They may use different definitions, discuss different situations or write about different periods. Where one author criticises another, consult the original statement if available. Relying entirely on someone else's summary of a disagreement makes a fair assessment more difficult.

Jerzy Stelmach and Bartosz Brożek's “Metody prawnicze. Logika, analiza, argumentacja, hermeneutyka” gives separate attention to different approaches to legal inquiry. It is a useful starting point for further methodological reading, rather than a ready-made plan for every chapter. Select and justify the tools needed for your particular question.

An example: turning a collection into an argument

Choose an expression in the provision that raised a question during your reading and write down two possible readings: narrower and broader. Under each, leave space to explain what it would include and exclude. Now open the reasons for the judgments you found and check whether the courts actually discuss that difference. You are testing an idea at this stage: do not assign anyone a position simply because it fits your provisional division.

The apparent conflict may turn out to reflect different case contexts. Explaining that difference is then a valuable finding. There is no need to preserve a disagreement announced at the outset. If the disagreement remains, identify the argument you find more persuasive, explain the premises of your assessment and state which reservation remains unresolved.

Build an analytical paragraph

Open the paragraph by naming one difference you want to explain. Introduce the relevant passage from the reasons and explain in your own words why the court adopted that reading. Compare it with another judgment or an author's statement if it addresses the same issue. End by saying what the comparison establishes and what it leaves unresolved. A footnote lets readers find the source; your sentences must explain how the quoted passage supports the conclusion.

Instead of writing “author A says…, author B says…, author C says…”, open with the point of disagreement: “The positions differ over whether the wording or the provision's function should carry greater weight.” Then document the difference and check whether that contrast is justified. This requires understanding the texts, but avoids producing a chapter that is merely a catalogue of names.

During revision, remove claims that go further than your analysis. “Always leads to” is stronger than “was associated with in the cases examined”. A precisely identified uncertainty does not automatically weaken a thesis. It shows the conditions under which your conclusion can be accepted.

Test one issue before writing the chapter

Before committing to dozens of pages, prepare a short analysis of one argument. Choose a relevant provision, a judgment with full reasons and a publication addressing the same problem. The aim is not to satisfy a fixed source count. It is to see whether you can connect what the materials say. In one or two pages, state the question, the necessary findings and a cautious conclusion. Keep a separate note of what remains unknown and which document could help fill that gap.

This trial can reveal several difficulties. The judgment may merely mention the concept while deciding a different issue. Several publications may repeat one statement without independent reasoning. You might also be comparing material from different legal systems without explaining the differences. Each discovery is a reason to refine the search or question. It need not mean abandoning the entire topic.

Take this sample analysis to your supervisor together with a short plan and your selection criteria. You can then discuss a concrete decision: whether an additional period, other judgments or a more precise definition are needed. Alongside asking whether the topic is suitable, ask whether your material can support an assessment of the argument and whether the proposed boundaries match the seminar's requirements.

Legislative materials and your own assumptions

An explanatory memorandum, consultation document or record of legislative proceedings may help identify the stated reasons for a proposal. Specify the type of material and its relationship to the version you analyse. A participant's statement does not automatically become the content of the enacted provision. Check whether the final text retained the solution discussed earlier. Supporting material should clarify a particular issue instead of creating an appearance of extra authority.

Treat your own hypothesis with similar care. It can guide the search if the seminar uses that approach, but should leave room for a different answer. “The broader interpretation better serves the provision's purpose” requires both establishing that purpose and justifying the comparison. Calling it a hypothesis and collecting agreeable quotations is insufficient. Sometimes an open question about the reasons for each position is more useful, with an assessment reached after the analysis.

Make the plan follow the reasoning

Give each chapter a specific job when planning. The first might explain your chosen expression and the provisions needed to understand it. The next can show where the judgments read it differently, followed by a comparison of their reasoning with the literature. The final part should lead to an answer to your research question. Chapters need not be equally long. Labels such as “theory” and “practice” will not by themselves tell you what to write.

For every subsection, complete the sentence “After this part, the reader will understand…”. If two sections perform exactly the same task, consider combining them. If a subsection is unnecessary to answer the question, check whether it merely expands the background. The Bachelor's and master's thesis plan – how to prepare for a meeting with your supervisor? can help.

Separate findings about the law from proposals for change

The conclusion should answer your research question, rather than repeat the chapter contents. Distinguish findings about the regulation and its interpretation from proposals to change the law. A proposal for a better solution requires an explicit evaluative criterion and an explanation of what would improve.

Describe limitations involving dates, available reasons, database selection and the comparability of cases. Do not present a selected collection as all case law. The frequency of an argument in that collection is not automatically a measure of its legal importance. Likewise, do not infer citizens' experiences without material capable of showing them.

Check the chapter before submitting it

• Do the question, method, sources and conclusions concern the same problem?
• Have you checked legislative versions and case context for the important documents?
• Can readers distinguish your argument from a reported position and a judgment summary?
• Do you address counterarguments and explain material selection?
• Does every subsection contribute something needed for the answer?
• Do the final claims stay within the evidence?

Check source formatting separately using the guide to Polish legislation and case law in thesis references and footnotes: examples. It helps document the analysis. Depending on your stage, relevant support may include Help with your thesis outline and structure, Literature search and selection for your thesis or Bachelor’s and master’s thesis proofreading and editing.

Finally, read only the beginning and ending of each subsection. Check whether the transition is understandable without the reader guessing your intentions. Locate the explanation of any newly introduced concept. State any change in period or scope. Select several key sentences and reopen their sources, checking both factual accuracy and whether the cited passage actually supports the claim attributed to it. A correct page number cannot repair an argument that the source does not contain.
