This appellate decision from 1993 (h/t Volokh) is interesting to read, as much for its content as for the decision.
It tells a life story and a legal story, but the quality of the writing is what most impressed me. That judge's clerk can write, and knows how to tell a Dickensian story. (Clerk informs, judge decides, clerk writes.)
Correction via reader: Judge Posner writes his own opinions!
