Oh no, I think that's been misunderstood. In the committee to which I'm not a member, I think everyone here agrees I'm a member of the public and would have to leave and can't record any more. The comments in this thread were made because the Chair decided that myself and another Councillor weren't members of the public to stop us asking a question in the public speaking section of the meeting. In the thread, we were just pointing out the flaw in her logic because if, by her own decree, we weren't members of the public, we wouldn't have to leave for any "closed session".
In terms of recording a closed session just above, I was referring to making a recording of a closed session of a meeting that I was entitled to attend (i.e. a full council meeting). The law you pointed to suggests that I can record a closed session of a meeting I'm entitled to be a part of so long as I don't share that info with anyone not in that meeting (e.g. a member of the public, a district councillor, etc). Sorry, I should have made that clearer.
