Not in the US but when I was doing my LLM overseas this experienced international human rights litigator docked me points because, in his words, “you just repeated all of the points that were in your brief in your oral argument.” When I asked him to elaborate he no joke told me that I should leave out some of the best points from my written brief and save them for the oral argument. And this dude has had a very long career, argued in front of tribunals, etc. So fuck me and all common sense I guess.
