Case Law Research: Citation & Keyword Strategies

1. Decoding the Language of Case Law: Citations

Before you can find a case, you need to understand how it's referenced. Every published court decision has a unique identifier called a citation. Think of it as the case's mailing address, guiding you to its exact location in a series of books called "law reporters."

Let's start with a short video that explains the concept of case law and breaks down the structure of a typical citation.

As the video explained, a standard citation contains all the information you need to locate the case. Let's look at this visually.

In recent years, courts have also adopted a "neutral citation" format. This format is independent of any commercial publisher and identifies a decision based on the year, the court, and a unique case number.

To dive a bit deeper into these components, the following resource provides clear definitions. Your law degree has likely exposed you to these concepts, but a professional-level understanding is crucial.

2. Method 1: Finding a Case with a Known Citation

This is the most straightforward research task you'll have. An attorney might email you saying, "Please pull up Harris v. Forklift Systems, 510 U.S. 17." Your job is to take that citation and retrieve the full text of the decision.

Let's watch a demonstration of how to do this using a free and powerful tool, Google Scholar.

As you saw, the process is simple:

1. Navigate to the legal research platform (e.g., Google Scholar, Westlaw, LexisNexis, CanLII).
2. Ensure you are searching within the "Case Law" database.
3. Enter the citation into the search bar.

The platform's "citation index" will recognize the format and retrieve the corresponding document. This works on virtually all legal research databases, not just Google Scholar.

3. Method 2: Finding Cases with Keyword Searches

More often, you won't have a specific citation. Instead, you'll be given a set of facts or a legal question, such as, "Find cases that define what constitutes a 'hostile work environment' under employment law."

This is where your skills from our lesson on Boolean searching become critical. The goal is to combine keywords and legal concepts to find relevant case law.

Let's review the strategy. This document from the Law Society of British Columbia provides a perfect, practical example.

Now, let's see this keyword search strategy in action. We'll return to the Library of Congress video, where the presenter searches for cases on "hostile work environment."

The key steps for a successful keyword search for case law are:

1. Brainstorm Keywords: Identify the key legal terms, facts, and concepts related to your issue.
2. Construct a Search Query: Use Boolean operators (AND, OR, NOT) and quotation marks ("...") to create a precise search, just as you learned in the previous module.
3. Execute the Search: Run your query in the case law database.
4. Filter and Refine: This is the most important step. Use the database's filters to narrow your results by:
   • Jurisdiction/Court: Limit results to the Supreme Court, a specific Federal Circuit, or a particular state/provincial court system. This is essential.
   • Date: Focus on more recent cases if the law has been evolving.
   • Relevance or "Most Cited": Sort the results to see the most important cases first.

A Preview of the Next Step: Is This Case Still Good Law?

Finding a case is just the first step. Law changes. A case from 1988 might have been overturned by a higher court in 1990, or later courts might have disagreed with its reasoning. Relying on an outdated or overturned case is a major professional error.

Therefore, after finding a case, you must always check its subsequent history. This process is often called "noting up" or using a "citator." These tools show you every subsequent case that has mentioned your case.

Google Scholar has a basic version of this feature called "Cited by." Let's see how it works.

This "Cited by" feature is a powerful tool for finding more related cases, but as the video notes, it has limitations. Professional-grade citators like KeyCite (Westlaw) and Shepard's (LexisNexis) use special symbols or flags (e.g., a red flag for negative treatment) to instantly tell you if a case is still "good law."

Conclusion

Excellent work. Today, you've learned the essential, practical skills for finding case law—a task you will perform countless times as a legal assistant. You now know how to take either a specific citation or a general legal issue and efficiently retrieve the relevant court decisions.

Key Takeaways:

• A case citation is a unique address that includes the parties, volume, law reporter, page number, court, and year.
• You can find a case instantly by entering its citation into the search bar of a legal database.
• To find cases on a topic, use keyword searches with Boolean operators, then aggressively filter your results by jurisdiction and date.
• Finding a case is not enough. The next crucial step is to verify its status to see if it's still "good law," a process we briefly introduced with the "Cited by" feature.

Preview of the Next Lesson:
In our next lesson, we will dive deep into that final, critical step: verifying the currency and validity of legal sources to ensure they are good law. We will move beyond Google Scholar's basic "Cited by" feature and learn how to use the professional citator tools that law firms rely on to guarantee the accuracy and authority of their research.
