Legal Research Synthesis & Authority Analysis with Casetext
Synthesize case law and analyze legal authority with Casetext
What You Can Do

Claude helps you extract key holdings, organize authorities by jurisdiction and strength, and identify patterns across multiple cases to build stronger legal arguments and research memos.
Features
Research relevant authorities without manual filtering across thousands of cases
Automatically identify key holdings and rank them by jurisdiction and precedent strength
Evaluate whether cases are binding, persuasive, or merely instructive for your jurisdiction
Create visual relationships showing how authorities support or contradict each other
Produce organized, citation-ready research summaries with proper authority hierarchy
Focus research on controlling authorities versus persuasive authorities by court level
Use pre-built templates for case syntheses, authority tables, and legal issue briefs
Example Output
Example 1: Authority Analysis Table
| Case | Court | Year | Holding | Authority Type |
|---|---|---|---|---|
| Smith v. Corp A | VA Sup. Ct. | 2019 | Non-competes enforceable if reasonable in scope | Controlling |
| Johnson v. Tech Co. | VA Ct. App. | 2018 | Duration of 2 years presumed reasonable | Supporting |
| Blue v. Consulting | 4th Cir. | 2016 | Virginia law applies; similar to federal standard | Persuasive |
Example 2: Case Synthesis
Virginia courts enforce non-compete agreements in employment contracts when: (1) they protect legitimate business interests (trade secrets, customer relationships), (2) the restricted territory and duration are reasonable, and (3) the restrictions do not impose undue hardship on the employee. Smith v. Corp A, 456 Va. 123 (2019). Courts presume reasonableness for restrictions under 2 years and within the employer's existing service territory. Johnson v. Tech Co., 275 Va. App. 567 (2018).
Example 3: Research Memo Structure
Issue: Are 3-year non-competes enforceable in Virginia technology employment?
Conclusion: Likely enforceable if they protect legitimate business interests and the restricted area/duration are reasonable.
