Published opinions are a small fraction of what federal courts produce. The strategy lives in complaints, motions, and orders, and that material only became searchable at scale once AI could read dockets rather than headnotes.
Federal litigation research has a coverage problem that predates AI. The tools most lawyers grew up with index published opinions. Published opinions are a small and unrepresentative slice of what a federal court actually produces.
Most of what determines an outcome never gets published. It sits in complaints, motions to dismiss, oppositions, replies, discovery orders, and one-line text entries on a docket sheet.
A keyword search over published decisions cannot answer the questions that come up in practice:
None of those questions is about the law. They are about behavior, and behavior is recorded on dockets.
A docket sheet is a chronological list of every filing and order in a case, with dates. Read across a few thousand of them and patterns appear that no single case shows: how long motions sit before a ruling, which judges rule from the bench, how often extensions get granted, whether cases in a district settle before or after summary judgment.
That is a structured dataset hiding inside unstructured documents. Extracting it by hand is possible and nobody does it, because reading ten thousand docket sheets is not a use of anyone's time.
Three things, concretely.
Summarizing long filings. A 200-page complaint with exhibits takes an hour to skim and ten minutes to summarize badly. A model reads it and returns the claims, the parties, the jurisdictional basis, and the relief sought, and it does so consistently across a hundred complaints.
Answering questions in natural language across a corpus. Instead of guessing at search terms, you ask what you actually want to know. The gap between "what a lawyer wants to know" and "what a keyword search can express" has always been the real cost of legal research.
Extracting structure. Party names, case numbers, dates, statutes cited, and relief sought can be pulled out of documents reliably enough to aggregate.
A model will produce a fluent, confident, wrong answer if the underlying document does not support it. Citation fabrication is a documented and sanctionable problem in federal courts. Several judges now require certification about AI use in filings.
The discipline that fixes this is unglamorous: never rely on a summary you have not traced back to a document. A research tool that shows you the source filing behind every claim is doing something different from one that just answers. Ask which one you are using.
Judge research stops being anecdotal. Instead of asking a colleague what a judge is like, you look at the record of how that judge has handled comparable motions. That is what our federal judge lookup is built to surface, and the underlying method is described in more detail in how to research a judge's track record.
Monitoring stops being manual. Nobody should be refreshing a docket page. Our case alerts watch dockets and push new entries, and the workflow is covered in how docket monitoring changes litigation practice.
Cost changes too. PACER charges $0.10 per page with a $3.00 cap per document, and no cap at all on search result pages or transcripts. Fees are waived if you spend $30 or less in a quarter, and the PACER fees guide breaks the rest down. That pricing punishes exploration: you pay to find out a document was not what you needed. Checking the free RECAP archive before paying is the single most effective cost control available, and it is the first thing any serious workflow should do.
Start with the docket, not the opinion. Read the complaint and the operative motion before anything else. Use AI to triage what to open, then open it. Verify every proposition against the filing before it goes in a brief.
If you want the reporter's version of this workflow, which is more aggressive about cross-referencing outside sources, see how journalists investigate federal court cases.
Search the federal record here: search federal cases. Pick a case you already know well and see whether the docket tells you something the coverage did not. It usually does.
Can you open the source? If the tool cannot show you the filing behind a claim, treat the claim as a lead rather than a fact.
Does the citation resolve? Check that the case exists, that the docket number matches, and that the quoted language appears in the document. Fabricated citations have produced sanctions in federal court.
Is the document current? A summary generated from a 2024 filing will not know about a 2026 order. Check the docket date.
Does the court have a standing order on AI use? Several districts require certification. That is a local rules question, and local rules change without announcement.
None of this is exotic. It is the same verification a lawyer applies to a summer associate's memo, applied to a faster and more confident writer.
