Kindly see the emboldened sentence. What does it mean? Just because "facts fall under the general rule, but not the more nuanced cases" doesn't mean your facts don't relate to those cases. Analogies are never a perfect fit. I think the author wrote this, but I can't remember which page. If every new factual matrix fell under nuanced cases, then we wouldn't need judges.
During the ‘A’ [Application] portion of your essay, you are, in a sense, justifying the inclusion of every legal reference you have made in the ‘R’ [Rules] portion of your essay. If you cannot draw a direct link from a fact to any of the cases and statutes you have mentioned, then reconsider whether you should include that fact in your essay. This is what is meant by having the facts in the back of your mind as you write (or, even better, as you plan) the rules section of your paper. Of course, the reverse is true as well: do not introduce a case or statute unless it relates to a fact you intend to discuss. If you take the time to think about the application step before you begin writing your essay, then you know that you are introducing each of your cases and statutes for a reason. The ‘A’ step is when you explain that reason.
Once it comes time to discuss the sub-issues that are primarily in dispute, you may not have to note how the facts fall under the general, leading precedent for that area of law. Instead, you will focus on explaining how the facts apply to the more specific cases that flesh out the bare bones of the general precepts of law. Because you have explained in the ‘R’ section that these cases are merely more specific manifestations of the general standard, you often can get by without evaluating the facts with reference to the general cases. Alternatively, you might find that you can demonstrate how your facts fall under the general rule, but not the more nuanced cases. This means that the claimant fails to meet the required standard for the prima facie case. Use your judgment as you balance what needs to be said versus what can be implied. As stated earlier, it is dangerous to rely implicitly on an examiner’s understanding of your mental processes, but there are times when you do not need to spell out everything.
