The Legal Memo as Literary Genre

Can anyone think of a book which uses them almost exclusively? Real life has provided some very good models, as you know if you follow the news. I could imagine someone publishing the Yoo memos, as is, in chronological order, in 1997, and winning all relevant prizes.

I feel like there’s an obvious example, but I refuse to research it; and I know that one of my erudite readers will supply some examples, if they exist.
