There are many humorless and poorly written legal opinions out there, but there are also plenty of excellent ones, excerpts of which I find myself writing down. Here's one from a patent case I just read -- Phillips w. AWH:
Eloquent words can mask much mischief. The court's opinion today is akin to rearranging the deck chairs on the Titanic - the orchestra is playing as if nothing is amiss, but the ship is still heading for Davey Jones' locker.
And from the oral argument in the recent Henderson v. United States:
Justice Scalia: I can also not imagine a lawyer who intentionally makes that decision. That lawyer is a unicorn I suppose.
