Compare River of Life Kingdom Ministries v. Village of Hazel Crest (PalatinoLinotype, F.) with United States v. Blagojevich (HoeflerText, F.). I side with PalatinoLinotype, which seems thinner and less busy — and avoids the unfortunate capital Q of HoeflerText, see the top of p. 7 of Blagojevich.
UPDATE: I am told that this is a rare departure from consistency, stemming from the fact that Blagojevich was a rush opinion (argued June 29, decided July 2, because of the especially time-sensitive nature of the question), and is therefore being “released in typescript.” But, still, why have a different font for “typescript” opinions than for “printed” opinions? It’s not like they didn’t have the time to enter it into the computer, and so had to type it on a typewriter that only had the HoeflerText font.
