I'm not a law lecturer. I spend most of my time wrangling contracts and advising about data law. But I did a stint of part-time work teaching a masters in law.

My experience then (this was back before "Attention Is All You Need", I hadn't met the output of generative models) was that students tended to produce work that did not have a proper thread of reasoning in it. There was a tendency to repeat things they had read but rehashed in various ways.

Reviewing some of their texts it was clear that much of the writing - by law tutors - was of the same kind. Much was incorrect. The fact that someone at some time had said a particular case was a proposition for something, meant that got repeated from book to book. Many authors simply didn't read their sources or check their references. Students repeated what they had been told incuriously.

Note: this was a graduate level course. Not wet about the ears undergraduates.

The worst material was little potted notes produced for law students. Utterly awful material in most cases.

Anyway, when LLM's became a thing, a lot of what did not feel right about their output and many of their error patterns, reminded me of the experience of teaching masters' students.

One of the saving graces of English court room practice (when I did that sort of thing) was that judges would say to you "where does it say that?" in a case you cited. You had better have them all at your fingertips and know exactly where you had cited. That avoided a lot of hallucination.

Just a random remark which might be of interest.
