Legal research is the NCBE Foundational Skills legal-research skill, specified by Tasks 21-24: formulate research questions and a strategy, conduct research using appropriate sources, evaluate and use legal authorities, and update research while determining sufficiency. A task gives you an assignment, facts, and legal resources. A good response produces a traceable path from the assignment to current, supported legal propositions. Skills items supply the governing law, and the exam measures what you do with those materials. Any task may assess skills from any skill group, so the group labels do not limit what may be tested.
Task 21 begins before a search box. Convert the assignment into a tree:
For example, “Can the buyer end the supply arrangement and recover replacement costs?” becomes separate questions: What event permits termination? Was the required form of notice used? Does an exception eliminate notice? What consequence follows from a valid termination? Each question should be answerable by a rule, statute, regulation, or holding.
Write propositions, not vague topics. “Supplier breach law” is a topic. “A written refusal to make any further deliveries eliminates a separate cure notice” is a proposition that can be searched and verified. Mark each proposition as must establish, possible exception, or counterargument. Do not decide the answer merely by wording the question confidently.
Record the jurisdiction and relevant date at the top of the tree. A proposition can change when the governing court, transaction date, or procedural posture changes. If the assignment asks for advice about one motion or one transaction, state that practical endpoint so research does not drift into unrelated doctrine.
Task 22 gives you a legal problem and sources that may include statutes, rules, opinions, regulations, databases, or explanatory material. Begin with the highest-authority source reasonably available, then use other sources to find terms, citations, distinctions, and contrary authority.
Run this sequence on the clock:
Use several formulations. Search the exact phrase in a supplied rule, then substitute ordinary synonyms and the factual description. Add the court or jurisdiction, a distinctive phrase, and terms such as “exception,” “notice,” “remedy,” or “enforcement” when those match the question. Search citations backward for authorities relied on and forward for later treatment.
A query log can be brief but must be reproducible:
A log prevents repeated searches and exposes an unsupported proposition. It also lets another reader distinguish “no authority found” from “authority searched and found inapplicable.”
Task 23 requires more than collecting favorable language. For each source, ask whether it governs the jurisdiction and question, what legal force it carries, whether it remains current, and whether the text is complete and authentic.
| Source type | Question it answers | Force in the answer | Main risk |
|---|---|---|---|
| Governing statute or rule | What enacted text controls? | Controlling if applicable | Missing definitions, exceptions, or effective dates |
| Binding opinion | How does the governing court interpret the text? | Binding within its proper jurisdiction | Quoted language may exceed the actual holding |
| Persuasive opinion | How has another court reasoned? | Persuasive only | Different jurisdiction, facts, or legal test |
| Treatise or practice guide | Where are authorities and distinctions located? | Usually explanatory, not controlling | Incomplete, outdated, or oversimplified account |
Check jurisdiction in layers: issuing body, geographic reach, court level, and whether the source addresses the same legal question. A later trial decision may be informative but cannot displace controlling higher authority. A secondary source may identify the right phrase or overlooked decision, but verify its assertions in the underlying primary source.
Check currency separately from force. A binding opinion may have been limited, reversed, superseded by legislation, or affected by an amended rule. A database label is a lead, not proof. Read the official text when available, including amendments and effective dates.
Do not treat a search-result summary, headnote, editorial quotation, or isolated sentence as the law. Compare the source’s rule with its facts and disposition. Ask whether the language is necessary to the result or merely an illustration. Record the strongest contrary authority, not only the most convenient source.
Read an opinion in an order that preserves its legal function: identify the court and posture, find the disposition, locate the issue presented, then read the facts and reasoning that support that disposition. The question is not “What sentences sound useful?” It is “What proposition did this court actually decide, on which facts, and with what limits?”
Use this extraction grid for every important opinion:
Add two notes while reading. First, identify dicta: reasoning not necessary to the judgment. It may be persuasive, but do not present it as the holding. Second, identify the best analogy and distinction. An analogy transfers the court’s reasoning to materially similar facts; a distinction explains why a difference may prevent that transfer.
The opinion’s factual narrative is not decoration. If the court relied on a written refusal, a particular notice, or a specific procedural stage, those details may define the proposition’s limits. The result alone cannot tell you whether the court adopted a broad rule or resolved a narrow dispute.
Dana Ortiz runs a neighborhood bakery in a converted garage, where she sells sourdough loaves to three cafes. In January, she signed a recurring-delivery agreement with North Mill for 200 pounds of flour each month. The agreement was still running in March when North Mill’s manager, Evan, emailed Dana: “North Mill will not make another flour delivery under our agreement, even if you pay in advance.” Dana saved the email, bought flour from a more expensive mill, and sent North Mill a written cancellation that afternoon. She did not send a separate notice describing the missed March delivery or allowing North Mill time to cure. North Mill later demanded payment for the remaining months and argued that Dana ended the agreement too quickly. Dana wants to know whether her cancellation was effective and whether she may seek the extra cost of replacement flour. The supplied authority states:
Food Supply Rule: A buyer may end a written agreement for recurring food deliveries without giving a further cure notice when the seller has sent a written statement that the seller will not make any further deliveries under that agreement. If the seller’s statement is conditional or does not clearly concern the agreement, the buyer must first give written notice describing the missed delivery and a reasonable chance to cure. A buyer who properly ends the agreement may recover the reasonable extra cost of substitute goods bought in good faith.
Practice
Which research conclusion is best supported by the supplied authority?
An integrated question set or performance task would demand a short constructed response rather than a selected choice:
Dana’s cancellation is supported by the supplied Food Supply Rule. Evan’s email was written, unconditional, and expressly concerned further deliveries under the existing agreement, so Dana did not need to give a separate cure notice. The rule also supports recovery of the reasonable extra cost of substitute flour because Dana bought replacement goods after the refusal. The facts supplied do not establish the amount of that cost, so the response should state the entitlement without inventing a dollar figure.
This response is good because it ties each conclusion to a specific supplied condition. It also separates the legal proposition from a factual amount the materials do not establish.
Task 24 gives you an existing research trail or authority set and asks whether the answer remains reliable. Recheck the current text of each controlling provision, its amendment history, the effective date, and later decisions that interpret or displace it. For opinions, run the citator or equivalent treatment check, read the citing decision rather than relying on a warning symbol, and record whether the treatment is favorable, limiting, negative, or unrelated.
Revisit the trail when a fact changes. A new forum, transaction date, procedural posture, remedy, or disputed exception can require a new branch of research. Revisit it when the question changes from “What is the rule?” to “What is the likely result?” because the latter may require decisions applying the rule to comparable facts.
Use this sequence:
Loading diagram…
A source is not current merely because the database displays it. The update record should state what was checked, on what date, and why the result does or does not affect each proposition.
Research is sufficient when four conditions are met. First, every material proposition in the question tree has support. Second, the strongest available authority has been identified and its jurisdictional force is understood. Third, the authority is current, with amendments and negative treatment checked. Fourth, meaningful disagreement or uncertainty is stated rather than silently ignored.
Stop when a new search is producing duplicates, weaker sources, or facts that cannot change the answer. Do not stop merely because one favorable opinion appears. Conversely, do not continue indefinitely because a database contains more results. A practical assignment needs a supported answer, not an inventory of every publication.
Before stopping, ask:
If the answer to a material question is “no authority found,” say exactly what was searched and whether the gap reflects unsettled law, a changed fact, or an incomplete search. A clear uncertainty is better than a confident proposition resting on a secondary summary.
Common errors include:
Practise with supplied statutes, rules, opinions, and database-style excerpts. Set a time limit, build the question tree, run the search sequence, and write the extraction grid without copying undigested language. After each attempt, record the proposition you missed, the query that found it, the source’s legal force, the update check performed, the unresolved disagreement, and the precise reason you stopped.
Break assignments into discrete propositions before selecting search terms. Primary authority supplies force while secondary authority supplies leads and context. Read each opinion through facts issue holding reasoning limits and later treatment. Stop only after current support covers every material proposition and disagreement is accounted for.

1. A junior lawyer represents a delivery company defending a federal employment lawsuit. The lawyer finds a published federal trial-court decision interpreting the relevant federal statute in the company's favor and drafts a motion relying on it. Before filing, the lawyer discovers a later published opinion from the federal court of appeals governing that trial court. The appellate opinion interprets the same statutory language more narrowly and expressly rejects the trial decision's reasoning. The appellate opinion has no negative treatment, but the lawyer has not checked whether later legislation amended the statute. The client wants an accurate assessment and does not want to incur the cost of filing a motion that lacks a reasonable legal basis. What is the most appropriate next step?
Answer: B. Read the appellate opinion, confirm its current treatment, and revise the draft to apply the appellate court's controlling interpretation.
Read the appellate opinion, confirm its current treatment, and revise the draft to apply the appellate court's controlling interpretation. - The governing federal court of appeals controls the trial court and expressly rejected the favorable trial decision’s reasoning. - Before advising the client or filing, the lawyer should check for later statutory amendments as well as subsequent treatment, then assess whether the motion has a reasonable legal basis. Rely on the trial decision because it addresses nearly identical facts and is the most factually specific authority found. - Nearly identical facts do not make a trial decision controlling when the governing appellate court has rejected its reasoning. - Relying on it without accounting for the later appellate interpretation would not give the client the accurate assessment requested. Cite both decisions as equally authoritative because conflicting opinions allow counsel to select the result most favorable to the client. - The decisions are not equally authoritative: the appellate interpretation governs the trial court hearing the company’s lawsuit. - Counsel may discuss the trial decision’s factual similarity, but cannot treat its rejected reasoning as an alternative controlling interpretation. Exclude both decisions and search only for statutes because judicial opinions cannot establish the governing interpretation of statutory language. - Judicial opinions can authoritatively interpret statutory language; here, the governing appellate opinion supplies the controlling interpretation. - The lawyer should also check whether later legislation amended the statute, rather than disregard either judicial authority or statutory developments.
2. Using only the supplied client file and legal resources, draft a confidential settlement proposal to MedAxis's counsel addressing disputed performance, payment, a verification process, operational continuity, mutual releases, and a response deadline. The proposal must advance the clinic's priorities without making unsupported admissions.
3. Using only the supplied file and legal resources, prepare an advisory memorandum evaluating TransitCo's settlement offer, explaining the principal liability and damages uncertainties, and recommending a reasoned response and negotiation range.
4. Using only the supplied file and legal resources, prepare a persuasive memorandum supporting Atlas Fitness LLC's motion to dismiss for lack of personal jurisdiction and identifying any factual development that could materially alter the analysis.

7. A pedestrian suffered a broken wrist when a delivery van struck her in a marked crosswalk. The van driver admits looking at a navigation screen immediately before impact, but contends that the pedestrian entered against the signal. A nearby restaurant may have exterior video, and the police report identifies two witnesses without recording their full statements. The pedestrian wants the lawyer to demand $150,000 immediately because she needs funds for treatment. The limitations period is not imminent, and the delivery company has asked for documentation supporting liability and damages. The client authorizes the lawyer to explore settlement but has not authorized a minimum acceptable amount. What is the most appropriate next step?
Answer: C. Preserve and obtain the video, interview the witnesses, document damages, and then discuss a supported demand and settlement authority with the client.
Preserve and obtain the video, interview the witnesses, document damages, and then discuss a supported demand and settlement authority with the client. - The restaurant’s potentially transient video and the two identified witnesses may clarify whether the pedestrian entered against the signal, while medical records will support a demand for the broken wrist. - The lawyer should discuss the evidence and the client’s urgent need for treatment funds before proposing a demand; permission to explore settlement does not give the lawyer authority to set or accept a settlement amount. Demand $150,000 immediately and characterize the driver's admission as conclusive proof of liability. - Looking at a navigation screen is significant evidence, but it does not conclusively resolve the driver’s claim that the pedestrian entered against the signal. - The $150,000 demand lacks documented support for liability and damages, which the delivery company has requested and the lawyer can investigate without risking an imminent limitations deadline. Accept any offer covering current medical bills because prompt payment is the client's stated priority. - The client’s need for prompt treatment funds does not mean she has authorized any settlement that covers current bills. - The lawyer must assess the broken wrist’s documented damages, including potential future losses, and obtain the client’s informed decision about a proposed settlement. File suit immediately to prevent the delivery company from learning weaknesses in the pedestrian's account before discovery. - Because the limitations period is not imminent, filing suit now is unnecessary to preserve the claim and will not replace prompt efforts to secure the video and witness accounts. - The disputed signal and incomplete damages record call for investigation and client counseling, not a filing intended to keep weaknesses from the delivery company.
8. A lawyer represents a cyclist injured when a delivery van struck her in a marked bicycle lane. The van company denies that its driver entered the lane and asserts that the cyclist swerved into traffic. The cyclist recalls seeing a city traffic camera at the intersection. An online search reveals a municipal policy stating that ordinary traffic recordings are automatically overwritten after 30 days unless the city receives a preservation request. The collision occurred 24 days ago. The lawyer has interviewed the cyclist but has not contacted the city, the driver, or nearby businesses. The client wants to preserve evidence without immediately filing suit. What is the most appropriate next step?
Answer: D. Promptly send the city a targeted preservation request identifying the collision, camera, location, date, and relevant time period.
Promptly send the city a targeted preservation request identifying the collision, camera, location, date, and relevant time period. - The city’s 30-day overwrite policy leaves about six days to preserve a recording that may resolve whether the van entered the bicycle lane. - A targeted request uses the city’s stated preservation process without requiring the cyclist to file suit immediately. File suit immediately because commencing litigation is the only reliable means of preventing destruction of government recordings. - The municipal policy expressly allows a preservation request to prevent automatic overwriting. - Filing suit is not necessary before using that process, particularly with only about six days remaining. Interview the delivery driver before taking action because witness testimony is generally more useful than an unreviewed recording. - An interview could help investigate the disputed accounts, but it does not preserve the city’s recording. - The recording may capture the van’s position in the bicycle lane and faces a known overwrite deadline. Wait for the van company’s insurer to disclose whether it disputes the cyclist’s account before incurring preservation-related costs. - The van company already disputes whether its driver entered the lane, so waiting for its insurer adds nothing to the preservation decision. - Delay risks losing the recording after day 30 regardless of what the insurer later says.
9. A junior lawyer is researching whether a federal statute permits a client's proposed claim. A database search identifies a published federal appellate opinion from the relevant circuit that supports the claim. The search results also show a red warning symbol beside the opinion but do not explain the symbol. A later federal trial decision quotes the appellate opinion while rejecting a similar claim, stating that an intervening Supreme Court decision “substantially narrowed” the appellate opinion. The client must decide tomorrow whether further litigation expense is justified. The lawyer has not yet read the appellate opinion, the Supreme Court decision, or the citing references. What is the most appropriate next research step?
Answer: A. Read the appellate opinion and use a citator to determine whether later controlling authority limited its reasoning.
Read the appellate opinion and use a citator to determine whether later controlling authority limited its reasoning. - The unexplained red warning symbol and the trial decision’s statement that an intervening Supreme Court decision “substantially narrowed” the appellate opinion make its current authority uncertain. - Reading the appellate opinion, Supreme Court decision, and citing references will show whether the proposed claim remains viable before the client decides whether to incur further expense. Cite the appellate opinion because published appellate decisions remain binding until expressly overruled by the issuing court. - An intervening Supreme Court decision may limit a circuit opinion without the circuit expressly overruling it. - Citing the appellate opinion without checking the reported negative treatment risks relying on reasoning that no longer supports the claim. Rely on the trial decision because it applied the appellate opinion to facts most similar to the client's facts. - Factual similarity does not make a federal trial decision controlling over the appellate opinion or the intervening Supreme Court decision. - The lawyer must read those higher-court decisions to determine whether the trial court’s interpretation governs the client’s proposed claim. Search only for decisions using the appellate opinion's exact phrase because broader searches would produce nonbinding authority. - An exact-phrase search can miss decisions that discuss or limit the appellate opinion in different words. - A citator and review of citing references are needed to identify relevant treatment, particularly by controlling courts.
1. What should a researcher examine when reading a judicial opinion?
Identify the material facts, procedural posture, issue, governing rule, reasoning, holding, and disposition. Distinguish the holding necessary to decide the case from dicta or broader observations.
2. What are the 'Three Fast Tests' for evaluating legal sources and opinions?
The three fast tests are: 1) Weight: Classify the source (primary/secondary) and measure its authoritative weight (binding/persuasive) for the specific proposition. 2) Fact Fit: Compare the material facts of the source to the current issue, identifying dispositive similarities or distinctions. 3) Direct Effect: Determine if the source directly resolves the legal issue or provides a controlling rule/application.
3. What are the four components used to build an effective legal research query?
1. The anchor (distinctive phrase from resource). 2. The subject (regulated activity/document/relationship). 3. The disputed operation (action/relationship being tested). 4. The narrowing term (jurisdiction, tribunal, agency, etc.).
4. What are the four tests for identifying and analyzing ambiguity in a legal resource?
1. Locate competing readings and mark the uncertain language. 2. Identify the type of uncertainty (semantic, syntactic, relational, temporal). 3. Test whether the uncertainty changes the legal operation. 4. Separate the text problem from the application problem.
5. What does 'The Supplied Authority Test' require a researcher to do?
It requires the researcher to meticulously examine the language of the supplied authority for explicit or implicit signals (e.g., effective dates, cross-references, agency delegations, instructions about later decisions) that necessitate further research to update or extend the record and ensure sufficiency.
6. What is the difference between primary and secondary legal authority?
Primary authority states or applies the law, including constitutions, statutes, regulations, and judicial decisions. Secondary authority explains or analyzes the law, including treatises, practice guides, law reviews, and legal encyclopedias.
7. How should a researcher update a statute, regulation, or case?
Check amendments, repeals, later cases, regulations, and other subsequent authority affecting the source. Use citators or equivalent tools to find negative treatment, distinguishing decisions, criticism, and later history, then read the citing authorities.
8. What information should a legal research log record?
Record the research question, search terms, databases or sources used, authorities found, relevant propositions, citations, and updating results. A log should also note unresolved issues and searches that produced no useful authority.
9. How can secondary sources be used effectively in legal research?
Use reliable secondary sources to learn terminology, locate primary authorities, and understand competing arguments. Verify every important proposition by consulting the cited primary authority and checking whether it remains good law.
10. Which authority is generally binding on a court?
A court is generally bound by higher courts in the same jurisdiction and, when applicable, controlling constitutions, statutes, regulations, and other enacted law. Decisions from other jurisdictions and most secondary sources are persuasive rather than binding.
