The Supreme Court has posted the transcript of the oral argument in Culbertson v. Berryhill, concerning attorney fees for federal court work. The argument was more spirited than I would have thought. I wouldn't predict the Court's decision in this case but I would predict that it won't be unanimous.
To my mind this is a straightforward plain language case. The statute says there's a separate cap on attorney fees for federal court. You can certainly make an argument that it shouldn't say that but that's what it says. If that's not what Congress intended, they can change the statute but it's not up to the Court to change it to something they think makes more sense. Judges or justices shouldn't use the plain language argument only when it suits their purposes and ignore it when they don't like the result. Plain language should always be the first consideration.
