What’s Coming
We’re adding a new data source in Harvey to provide comprehensive U.S. case law coverage. With this addition, lawyers will be able to conduct legal research and receive results grounded in relevant court opinions—all within a single platform.
Users will be able to filter and search across specific jurisdictions, view full case text directly in Harvey, and incorporate case law into custom Workflow agents and the Word Add-In. This will streamline research workflows and reduce the need to switch between external tools.
Harvey will include millions of cases available at no cost, with coverage across:
- Federal and state appellate courts, including the U.S. Supreme Court, state supreme courts, and intermediate appellate courts
- Federal district courts across all jurisdictions
- State trial courts in major jurisdictions, including California, Delaware, and others
- Federal and state statutes and regulations, accessible through Harvey’s U.S. public knowledge source and web search
The U.S. case law knowledge source will support key platform capabilities, including jurisdictional filtering, Multi-KS querying, Deep Analysis, integration with Agent Builder, and in-platform case viewing.
FAQs
Q: Will US Case Law be automatically enabled for all workspaces?
Yes, this will be a free offering that customers will receive by default. Admins can always choose to adjust knowledge sources enabled in their workspace under settings.
Q: Is the US Case Law knowledge source meant to be a full replacement for other legal research databases?
No, this is meant to be a complement to other research tools users rely on. Generally, users can use the US Case Law knowledge source for initial queries, as well as embedding in other Harvey platform features outside of Assistant.
Q:What are known limitations of the knowledge source?
The US Case Law knowledge source will not contain unpublished opinions and may have thinner coverage for certain state court decisions. The Ask LexisNexis integration will continue to provide the most comprehensive case coverage, along with Shepard's® citations.
