Case Law Sources, Coverage & Verification in Eve

Last updated: July 2, 2026

Overview

This article explains where Eve's case law comes from, how much of the law it covers, and how to verify results before relying on them. Eve's legal research runs on a purpose-built U.S. case law database that aggregates opinions directly from official federal and state court sources, so attorneys can validate the facts of the cited case and how current the ruling is.

How It Works

Sources — Eve's case law is drawn from official government repositories, including federal court filing systems such as PACER and state court portals, and is continuously ingested from federal and state court websites. Automated systems poll those court websites multiple times daily to capture newly published opinions. Statutory and regulatory content is sourced directly from authoritative federal and state government sites.

Coverage — The database spans more than 2,000 federal and state courts, including all federal appellate courts, federal district courts, and state appellate courts across all 50 states and D.C., plus rulings from select federal administrative agencies and specialized courts. It covers the substantial majority of federal and state appellate authority, including a significant volume of unpublished opinions. State trial court opinions are generally not included, and the database does not include secondary materials.

How opinions are stored — Every opinion is stored and indexed as full text, not summaries or editorial headnotes, so searches run against the actual language courts used. Each opinion is also processed to extract key attributes such as the authoring judge, docket number, case type, party names, and embedded citations, which enables precise filtering. The database maps the relationships between opinions, statutes, and regulations, which is the foundation for citation functionality and connected research across sources.

Recency — The database is updated daily, with most new decisions indexed within one business day of publication. Actual ingestion speed depends on how quickly each court makes opinions publicly available; some state courts and administrative agencies publish on slower or less predictable schedules, so very recent decisions from certain jurisdictions may not yet appear. For time-sensitive matters, confirm currency directly through the relevant court's website or docket system.

Verification — Citation history flags are designed for accuracy. They are a reliable starting point, but attorneys should always review the underlying citing references directly. Eve is designed to make thorough legal research faster, not to replace attorneys' professional judgment and verification standards.
