Longest in History?

Eugene Volokh points out that the campaign finance reform decision -- 298 pages and over 90,000 words -- may be the longest in history, and asks if anyone can think of a decision that was longer. The only candidate that came to my mind was Gibbons v. Ogden, 22 U.S. 1 (1824), but when I cut and paste that decision into a word processing program, it comes out to a mere 65,000 words.

Longest decision in history: A dubious distinction if ever there was one.
