Free US Case Law from Google! - US Federal + 50 State Case Law

Starting November 17, 2009, Google has placed full text legal opinions from the US Federal and State district, appellate and supreme courts using Google Scholar. You can find these opinions by searching for cases (like Planned Parenthood v. Casey), or by topics (like desegregation) or other queries that you are interested in. For example, go to Google Scholar, click on the "Legal opinions and journals" radio button, and try the query separate but equal.

This provides all citizens with a way to learn about the laws that govern us all.  You can explore citing and related cases using the Cited by and Related articles linkson search result pages. As you read an opinion, you can follow citations to the opinions to which it refers. You can also see how individual cases have been quoted or discussed in other opinions and in articles from law journals. Browse these by clicking on the "How Cited" link next to the case title.
