If you're not familiar with what "case law" is, and how to use it, check out Chapter 7 of Nolo's LegalResearch: How to Find and Understand the Law for a guide to how to read through a case to get the parts that matter.
Also, you need to be familiar with the concept of "jurisdiction." Here are some helpful links:
When you read a case, check to make sure that the case's decision applies to your local district. Do this by looking at which court has decided the case -- either the U.S. Supreme Court, a court of appeal (listed here in large type), or a district court (listed in small type). Your local district court judge is not bound to follow the opinion of judges from other district courts, but often they look to these cases for advice. Your local district, however, is bound to follow decisions in cases from it governing circuit court. You'll see fairly few Supreme Court case here, but those cases are also binding on all districts."
NO! NO! NO! This is a start for your research. New cases are constantly being decided. I update this when I have time. This is only a fraction of the actual published opinions out there. Dozens of cases are handed down nationwide every week. I catalog interesting ones when I have time. They are meant to serve as a starting point for your research -- NOT as a comprehensive listing of the current state of the law.
