If you begin by searching for articles on your subject, you'll get context for any case you find. You can then search for the case/decision/opinion in Google Scholar.
The idea is to identify a case in an article and then follow up by finding the decision. In some of the videos, I include that step but if I felt the video was already too long, I omitted it.
You might need to add one of these terms to your search to narrow it to articles involving a case/decision/opinion: court or legal or law. Adding case with yield a substantial number of articles with "case study" in them.
If you find an article that you really, really want but can't access, email me the COMPLETE citation and I'll look into getting it for you.
