This dataset organizes factual claims from summary judgment, dismissal, and evidence-exclusion motions, along with related opposition filings, for verification against the case record. Each record can include the original and normalized claim, supporting materials such as declarations, deposition excerpts, exhibit lists, or attachments, and labels for claim category, three-way verification status, assessment, and confidence. It supports legal fact-verification model training and evaluation, litigation document review, and case-record evidence analysis.

FAQ
Frequently Asked Questions
- What filings and information does the dataset cover?
- The dataset focuses on factual claims in summary judgment, dismissal, and evidence-exclusion motions and related opposition filings. Record materials may include declarations, deposition excerpts, exhibit lists, and attachments. Fields also cover normalized claims, claim categories, verification outcomes, assessments, and confidence scores.
- How are verification outcomes labeled?
- Outcomes use three categories: supported by the case record, contradicted by the case record, or indeterminate based on the available record. The assessment explains the relevant evidence and any unresolved issues.
- What quality and size specifications are available?
- The record design links original claims, normalized wording, case-record evidence, and an assessment to make the reasoning traceable; confidence is represented on a 0-to-1 scale. Sample count, file formats, and other statistical specifications are not provided here, so check the product details before use.
- How can I access the dataset, and what are its licensing and use terms?
- Check the product page for access methods, licensing terms, and permitted uses; the applicable license governs specific rights and restrictions. The dataset is suited to training and evaluating legal fact-verification models, reviewing litigation documents, and analyzing case-record evidence, but it does not replace attorney review or judicial decision-making.
