Case Law Precedent Research & Analysis
Research and apply case law precedents with proper authority hierarchy
What You Can Do
Systematically search for relevant case law, analyze the authority hierarchy of your sources, and construct legally sound arguments backed by proper precedent. You'll organize complex case law into coherent arguments, identify controlling vs. persuasive authority, and ensure your legal positions rest on solid precedential foundation.
Features
Search for and retrieve relevant cases by topic, jurisdiction, holding, and legal principle with structured query results
Automatically classify sources as binding, persuasive, primary, or secondary authority based on jurisdiction and court level
Compare multiple cases side-by-side, identify common holdings, reconcile apparent conflicts, and extract legal principles
Build multi-layered legal arguments by stacking precedents in order of authority strength and relevance
Verify legal citations for accuracy (Bluebook, ALWD), check for overruled cases, and format citations consistently
Identify opposing precedents, distinguish unfavorable authority, and prepare defensive arguments
Automatically organize research findings into professional legal memoranda, motions, and appellate briefs
Rank sources by persuasiveness—Supreme Court, circuit courts, district courts, secondary sources—to prioritize your strongest authorities
Example Output
Example 1: Precedent Authority Matrix
| Case | Court | Year | Holding | Authority Type |
|---|---|---|---|---|
| Smith v. Jones | SCOTUS | 2015 | Establishes bright-line rule on damages | Controlling |
| Brown v. State | 2d Cir. | 2018 | Distinguishes on facts | Persuasive |
| Green v. Fed. | D.N.Y. | 2020 | Follows SCOTUS precedent | Supporting |
Example 2: Argument Framework
Issue: Can plaintiff recover damages under § 1983?
-
Binding Authority (controlling)
- Smith v. Jones, SCOTUS (2015): Establishes elements of damages claim
- Brown v. State, 2d Cir. (2018): Applies to circuit
-
Distinguishing Opposing Authority
- Red v. Blue, D.N.Y. (2019): Distinguished because [fact difference]
-
Supporting Authority (persuasive)
- Green v. Federal, 3d Cir. (2017): Analogous fact pattern supports holding
Example 3: Case Synthesis Summary
Three lines of precedent converge on a narrow holding: Primary principle from controlling authority, refined by circuit precedent, and supported by persuasive secondary sources. Counterargument exists but is distinguishable on facts. Strongest position is [recommendation].
