Collaborative Open Legal Data (COLD) - Cases
COLD Cases is a dataset of 8.3 million United States legal decisions with text and metadata, formatted as compressed parquet files. If you'd like to view a sample of the dataset formatted as JSON Lines, you can view one here
This dataset exists to support the open legal movement exemplified by projects like Pile of Law and LegalBench. A key input to legal understanding projects is caselaw -- the published, precedential decisions of judges deciding legal disputes and explaining their reasoning. United States caselaw is collected and published as open data by CourtListener, which maintains scrapers to aggregate data from a wide range of public sources.
COLD Cases reformats CourtListener's bulk data so that all of the semantic information about each legal decision (the authors and text of majority and dissenting opinions; head matter; and substantive metadata) is encoded in a single record per decision, with extraneous data removed. Serving in the traditional role of libraries as a standardization steward, the Harvard Library Innovation Lab is maintaining this open source pipeline to consolidate the data engineering for preprocessing caselaw so downstream machine learning and natural language processing projects can use consistent, high quality representations of cases for legal understanding tasks.
Prepared by the Harvard Library Innovation Lab in collaboration with the Free Law Project.

Summary
Format
Apache Parquet is binary format that makes filtering and retrieving the data quicker because it lays out the data in columns, which means columns that are unnecessary to satisfy a given query or workflow don't need to be read. Hugging Face's Datasets library is an easy way to get started working with the entire dataset, and has features for loading and streaming the data, so you don't need to store it all locally or pay attention to how it's formatted on disk.

Notes on appropriate use
When using this data, please keep in mind:
- All documents in this dataset are public information, published by courts within the United States to inform the public about the law. You have a right to access them.
- Nevertheless, public court decisions frequently contain statements about individuals that are not true. Court decisions often contain claims that are disputed, or false claims taken as true based on a legal technicality, or claims taken as true but later found to be false. Legal decisions are designed to inform you about the law -- they are not designed to inform you about individuals, and should not be used in place of credit databases, criminal records databases, news articles, or other sources intended to provide factual personal information. Applications should carefully consider whether use of this data will inform about the law, or mislead about individuals.
- Court decisions are not up-to-date statements of law. Each decision provides a given judge's best understanding of the law as applied to the stated facts at the time of the decision. Use of this data to generate statements about the law requires integration of a large amount of context -- the skill typically provided by lawyers -- rather than simple data retrieval.
To mitigate privacy risks, we have filtered out cases blocked or deindexed by CourtListener. Researchers who require access to the full dataset without that filter may rerun our pipeline on CourtListener's raw data.
