Technically, Danzo didn't go through full preocedure of Hokage's election, he was yet to be approved by Jonins. So while he acted as Hokage during the summit, he was not officially one.

Also, as already pointed out, it was Kakashi who helped Sasuke. Naruto asked for less sever punishment for his friend, but ultimately it was Kakashi's call. And I am far from being Sasuke's fan, I still consider him an aweful character.
