Courtlistener

Courtlistener is an open-access legal research platform designed to make U.S. court information freely available and searchable. It aggregates case law, PACER documents, judicial profiles, and oral argument audio from federal and state courts, updating continuously as new documents are filed. Its primary purpose is to support legal research, transparency, and data-driven analysis of the judiciary by providing structured, searchable access to a vast collection of court records.

Key features include a powerful full-text search engine for opinions and orders, with filters for jurisdiction, date, judge, citation, and more. Courtlistener integrates PACER data, enabling users to view and track dockets and filings without navigating the PACER interface directly. Users can create alerts to monitor new opinions, docket updates, or activity involving specific parties, judges, or topics. The platform also offers judge profiles, citation networks, and bulk data access, supporting empirical legal research and advanced analytics.
