Advanced Legal Research Unit 2 ReviewAdvanced Case Law Research

Key Concepts in Case Law Research

• Case law research involves finding, analyzing, and applying court decisions to support legal arguments and predict case outcomes
• Primary sources of case law include court opinions, decisions, and judgments published in official reporters or online databases
• Secondary sources such as legal encyclopedias, treatises, and law review articles provide commentary and analysis of case law
• Jurisdiction is a key concept in case law research as it determines which court decisions are binding or persuasive authority
  • Federal court decisions are binding on lower federal courts within the same circuit and persuasive in other circuits
  • State court decisions are binding on lower state courts within the same state and may be persuasive in other states
• Precedent refers to prior court decisions that establish legal principles or rules that must be followed in similar cases
  • Stare decisis is the doctrine of following precedent to ensure consistency and predictability in the law
• Case law research requires understanding the hierarchy of courts and the weight given to decisions from different levels of courts
• Key information to gather from a case includes the parties, court, date, citation, holding, reasoning, and any dissenting or concurring opinions

Advanced Search Techniques

• Boolean operators such as AND, OR, and NOT can be used to combine search terms and narrow or broaden search results
  • AND requires all search terms to be present, OR requires at least one term, and NOT excludes certain terms
• Proximity searches allow you to find documents where search terms appear within a certain number of words of each other
  • Common proximity connectors include /s (in the same sentence), /p (in the same paragraph), and /n (within n words)
• Wildcards and truncation symbols can be used to search for variations of a word or phrase
  • The asterisk (*) replaces any number of characters, while the question mark (?) replaces a single character
  • Truncation symbols like ! or * can be added to the root of a word to find different endings (litigat* finds litigate, litigation, litigator)
• Field searching allows you to limit searches to specific parts of a document such as the title, court, judge, or date
• Natural language searching uses plain language queries and relevance ranking to find cases on a particular topic
• Citator services like Shepard's or KeyCite can be used to find later cases that cite a particular case and determine its treatment
• Advanced search techniques can be combined to create highly targeted searches that retrieve the most relevant cases on an issue

Analyzing Case Law Hierarchy

• The U.S. legal system has a hierarchical structure with federal and state courts at different levels
• The U.S. Supreme Court is the highest court in the federal system and its decisions are binding on all lower courts
• Federal courts of appeals (circuit courts) hear appeals from district courts within their geographic circuit
  • Circuit court decisions are binding on district courts within that circuit but only persuasive in other circuits
• Federal district courts are trial courts that hear cases arising under federal law or involving diverse parties
• State court systems typically have a similar three-tiered structure with a supreme court, appellate courts, and trial courts
  • State supreme court decisions are binding on lower state courts but not on federal courts or other states
• Decisions from higher courts are generally given more weight and considered mandatory authority for lower courts within the same jurisdiction
• Decisions from courts at the same level or from other jurisdictions may be considered persuasive authority if they address similar issues
• When faced with conflicting decisions, courts will usually follow the decision from the highest court or the most recent decision from the same court

Interpreting Citations and Reporters

• Case citations provide important information about a case and help locate it in print or online reporters
• The basic format of a case citation includes the case name, reporter volume, reporter abbreviation, page number, court, and year
  • Example: Brown v. Board of Education, 347 U.S. 483 (1954)
• Reporter abbreviations indicate the publication where the case is found, such as U.S. for United States Reports or F.3d for Federal Reporter, Third Series
• Parallel citations may be used to indicate that a case is published in multiple reporters
• Pinpoint citations or pincites direct readers to a specific page or paragraph within a case
• Parentheticals may be used to provide additional information about a case such as the holding, facts, or procedural history
• Official reporters are government-published reports of court decisions that are considered authoritative sources
  • Examples include United States Reports (U.S.) for Supreme Court cases and state-specific reporters like California Reports (Cal.)
• Unofficial reporters are commercially published and may include additional features like headnotes or key numbers
  • Examples include West's National Reporter System (e.g., F.3d, F.Supp.2d) and LexisNexis's reporters
• Online databases like Westlaw, Lexis+, and Bloomberg Law provide access to both official and unofficial versions of cases with advanced search capabilities

Using Digital Platforms and Databases

• Online legal databases like Westlaw, Lexis+, and Bloomberg Law are powerful tools for conducting case law research
• These platforms provide access to a vast collection of federal and state cases, statutes, regulations, and secondary sources
• Researchers can use advanced search features to quickly find relevant cases based on keywords, legal issues, or fact patterns
  • Natural language searching allows users to enter plain language queries and retrieve cases ranked by relevance
  • Boolean operators and field searching can be used to create more targeted searches
• Citator services like KeyCite (Westlaw) and Shepard's (Lexis+) provide information on the history and treatment of a case
  • These tools can be used to determine if a case is still good law and find later cases that discuss or criticize it
• Headnotes and key numbers are editorial enhancements that summarize key points of law and link cases on similar issues
• Online databases offer tools for organizing research such as folders, highlighting, and note-taking
• Mobile apps and offline access options allow for flexible research on-the-go
• Researchers should take advantage of user guides, tutorials, and customer support to learn advanced features and troubleshoot issues
• While online databases are convenient, it's important to double-check citations and quotations against official print sources

Tracking Case History and Treatment

• Tracking the history and treatment of a case is essential for determining its value as precedent and identifying any negative treatment
• Direct history refers to the procedural history of a case as it moves through the court system, including appeals and remands
  • A case may be affirmed, reversed, vacated, or modified on appeal, affecting its precedential value
• Subsequent history refers to later developments in a case such as rehearing, certiorari, or Supreme Court review
• Citing decisions are later cases that discuss or analyze a particular case, either positively or negatively
  • Positive treatment includes cases that follow, agree with, or distinguish the reasoning of a case
  • Negative treatment includes cases that criticize, question, or overrule a case
• Citator services like KeyCite and Shepard's use symbols and editorial analysis to indicate the treatment of a case
  • Red and yellow flags, for example, indicate that a case has been overruled or criticized, while green symbols indicate positive treatment
• Citators also provide a table of authorities that lists all the cases, statutes, and secondary sources cited within a case
• Researchers can use citators to validate the authority of a case, find related cases, and identify any weaknesses or limitations
• It's important to carefully review the language of citing decisions to determine how a case is being treated and whether it remains good law for a particular proposition

Applying Case Law to Legal Arguments

• Effective legal arguments rely on finding and applying relevant case law to support a position or predict an outcome
• The first step is to identify the key legal issues and relevant facts of a case or situation
• Researchers can then use search techniques to find cases that address similar issues or fact patterns
  • It's important to consider the jurisdiction, court level, and date of cases to determine their applicability and weight
• Cases that are directly on point or analogous to the situation at hand are most persuasive
  • Researchers should look for cases with similar facts, legal issues, and reasoning to the case at hand
• Distinguishing cases that seem to contradict a position is also important for anticipating counterarguments
  • This may involve pointing out differences in facts, legal issues, or procedural posture that limit the applicability of a case
• When applying case law, it's important to accurately represent the holding and reasoning of a case
  • Quoting directly from key passages and providing proper citations helps build credibility
• Researchers should also consider policy arguments and the potential impact of a decision on future cases
• Synthesizing multiple cases and weaving them into a cohesive argument is a key skill in legal writing
  • This may involve using parentheticals, explanatory phrases, or case illustrations to connect and distinguish cases
• Ultimately, the goal is to use case law to convincingly show how the rules and principles from prior cases should be applied to reach a desired outcome in the present case

Ethical Considerations in Case Law Research

• Legal research, including case law research, is governed by ethical rules and professional responsibilities
• Researchers have a duty to perform competent and diligent research to find the most relevant and up-to-date authorities
  • This includes using citators to validate the status of cases and fully Shepardizing or KeyCiting important cases
• Researchers must accurately represent the holdings and reasoning of cases and avoid mischaracterizing or misquoting authorities
  • Ellipses and alterations should be used carefully to avoid changing the meaning of quoted passages
• Researchers should disclose adverse authorities that contradict their position and address them in their arguments
  • Knowingly omitting or hiding unfavorable cases can be considered unethical and damage credibility
• Proper attribution and citation of sources is essential to avoid plagiarism and give credit to the work of others
• Researchers should be mindful of confidentiality and privilege issues when conducting research for clients
  • This may involve redacting sensitive information from documents or using secure communication channels
• Researchers should also be aware of any potential conflicts of interest that may arise in the course of their research
  • This could include personal, financial, or professional interests that may influence their objectivity or judgment
• When using online databases or other research tools, researchers should follow the terms of service and avoid misusing or sharing login credentials
• Staying current on changes to ethical rules, research platforms, and case law is part of the ongoing duty of competence for legal researchers
