CaseLite by Caseway searches published court decisions for the United States and Canada. Records include party names, courts, decision dates, docket or court-file identifiers, and citations when those fields are present in the source data.
Primary-law browsing (statutes, regulations, and related collections) is available for selected U.S. jurisdictions — currently California, Florida, New York, and Texas — plus Canadian federal, provincial, and territorial collections as published into the product. Coverage continues to expand as additional collections are released.
Decisions and legislative materials are ingested from official and published court-record and government sources. CaseLite does not generate opinion text or fabricate citations. When you open a result, you are reading structured metadata and documents tied to a real source identifier from the upstream publisher.
The same corpus underpins Casey, Caseway's AI research assistant. CaseLite is the direct search interface; Casey reasons across the same records with citations.
For redistribution, licensing, or bulk/machine-access questions about a specific collection, contact Caseway — do not assume every upstream licence permits unrestricted republication.
Incoming decisions are normalized into consistent metadata fields (parties, court, dates, jurisdiction, identifiers) and full-text indexed so keyword and citation queries can retrieve them quickly.
Ranking uses relevance and available date signals. Filters help narrow by what you already know about a matter rather than requiring expert search syntax.
Duplicates, amendments, and corrections are handled in the ingest pipeline; when a source issues a corrected or superseding document, CaseLite aims to reflect the updated record after the next successful ingest for that collection.
Public document counts change as ingest jobs complete. Treat any size claim as point-in-time: verify current availability inside CaseLite browse and search rather than relying on marketing adjectives.
U.S. case law: federal and state court decisions as published into the corpus. U.S. primary law browse: California, Florida, New York, and Texas (selected collections).
Canadian case law and primary law: federal plus provincial and territorial materials as published. Depth varies by court, statute set, and historical period.
New decisions and legislative updates are ingested on an ongoing basis as source systems publish them. Coverage depth and lag vary by court and jurisdiction; recent filings may appear after a processing delay.
When evaluating whether a collection is current, check the decision or consolidation date on the record itself and, for critical use, confirm against the official court or government publisher.
Questions about sourcing, coverage gaps, corrections, or takedown requests: [email protected]. Please include the CaseLite URL or citation so we can trace the record to its upstream source.
Counts and date ranges change as ingest jobs complete. Verify current availability inside CaseLite search and browse rather than relying on marketing summaries alone.

• Official court and government publishers (decisions, dockets, and primary-law consolidations where licensed)
• Published legal record feeds ingested under Caseway's data agreements
• No AI-generated opinion text — records link to real upstream identifiers
Methodology owner: Caseway legal data team ([email protected]). Last reviewed: September 2026.
• Not every court, tribunal, or historical period is equally represented. Absence of a case does not mean it does not exist.
• Metadata quality depends on the upstream source. Some older records may lack citations, dockets, or complete party strings.
• Primary-law browse outside the listed U.S. states and published Canadian collections may be incomplete or unavailable.
• CaseLite is a research aid, not legal advice. Confirm critical citations against the official reporter or court website when filing or advising.
• Search result pages on the CaseLite product are optimized for interactive use; durable public landing content lives on caseway.ai pages such as this one and CaseLite 使用方式.
