Legal professionals typically use specialized legal research platforms and analytics tools to analyze court decisions that are relevant to their clients’ cases.

Core tools lawyers rely on

  • Legal research databases like Westlaw, LexisNexis, Bloomberg Law, Clio Library, Fastcase, and Justia give access to case law, statutes, regulations, and secondary sources, with powerful search filters by jurisdiction, date, and issue.
  • AI‑enhanced research tools (for example Lexis+ AI, Westlaw Precision with AI, Casetext, and similar systems) summarize opinions, surface key passages, and suggest related precedents tailored to a specific fact pattern.
  • Citator and validation tools (Shepard’s on Lexis, KeyCite/TrueCite‑style tools) are used to check whether a case is still “good law” by tracking how later courts have treated that decision.

How they analyze court decisions

  • They search by keywords, issues, or natural‑language questions, then narrow results with filters like court level, procedural posture, and date to find the most on‑point precedents.
  • They use citators and analytics to see how often a case is cited, whether it has been followed or criticized, and how particular judges or courts tend to rule on similar issues.
  • They consult secondary sources (practice guides, treatises, law review articles) that explain how courts interpret certain doctrines, then map those interpretations onto their clients’ facts.

Litigation analytics and strategy tools

  • Litigation analytics platforms such as Lex Machina and other court‑data systems help analyze trends in outcomes, judge behavior, case duration, and damages across thousands of decisions.
  • These tools support strategic calls like venue selection, settlement posture, and predicting how a particular judge might handle a recurring legal issue.

Free and public resources

  • For quick checks, many lawyers and law students also look at free tools such as Google Scholar, CourtListener, FindLaw, the Legal Information Institute, and Justia to read opinions and basic summaries.
  • Free caselaw projects and Supreme Court archives provide historic decisions that can still be persuasive or binding, depending on the jurisdiction.

TL;DR: When analyzing court decisions relevant to a client, legal professionals don’t just “Google it”; they rely on dedicated legal research databases, AI‑powered research and analytics platforms, and citator tools to find, interpret, and validate the most applicable precedents.
