Let's see. It's a hard-core, blistering opinion. One that repeatedly slams not only the appellant (e.g., from the first paragraph of the opinion: "Blixseth has now filed a blunderbuss appeal." Or from the last paragraph: "Blixseth's claims are a transparent attempt to wriggle out of an unfavorable decision by smearing the reputation of the judge who made it), but also his counsel. By name. (Check out footnote 2.) Slams that the author makes sure get set forth in a published opinion.
The panel consists of Judges Kozinski, Paez and Berzon. It's a per curiam decision.
Which means, of course, that we can only wonder baselessly about who the actual author of this sharply worded opinion could possibly be.
