Each major premise in your motions and briefs must be supported by authority. The initial cases that you find after running a Google search are probably not your best ones. (Yes, we know that you use Google to research, but we won’t tell your clients. But we will tell the ethics commission if you try to bill those research “costs,” which you would never do, of course.)
So how should you select the best authority? I drafted a short article answering that question. Check it out at the Legal Writing Editor. And then share the article with your buddies.
