Say, one for students who feel strongly from the beginning that they do not want to become litigators, and would prefer to learn research and writing skills that would serve them better in non-litigating positions within public administration, or transactional settings, as examples. I understand that advanced legal research courses are available. I don't disagree that these are important things to teach law students. But here is the problem.
Most law schools have classes in the first year that concentrate mostly on case law analysis.
Through a legal writing class and Moot court problems, a statutory or even a legislative history dimension might be added to the mix. Few schools have required research courses after the first year. IMHO, law students are not ready to learn the regulatory stuff in the first year. They won't remember it because they don't need to know or remember it. So there is a timing question that is really difficult.
