Only four councillors didn't vote on the original ban. Two (Sarkis and Farouqi) had a leave of absence and Rahme was unable to attend and had sent his apologies.
Hamed left the room during the vote (apparently due to threats she'd received for voting on similar matters on the past).
The more significant point is that of the six who voted for the ban, five also ended up voting to repeal it (even two from Christou's own party).
