Yep, this is an odd one, as there is an argument for excluding press and public, as the agenda item was to establish a new role, albeit unpaid, but it could be considered to be a staffing matter. By "genuinely confidential", I'm referring to one of the topics listed in the legislation. But, as WhiteKnight pointed out, they discussed it in open forum, then had a confidential item later in the meeting, which may or may not be related to the same matter, by which time it appears they had decided to adopt a different approach to the whole issue by using a cooption.
