I did not even know there was a “other business” item, and will definitely utilise this point.
Strictly speaking, in NSW there is no “other business” item on agendas. The only issues that can be discussed, voted on and minuted must be detailed on the agenda (so that everyone can see in advance what is going to be discussed). However, some committees have an informal chat after the meeting has been declared closed, partly to decide which issues need to be on the agenda for the next time. To be fair, a lot of committees don’t follow correct procedure at all, but doing so leaves their decisions open to challenge at Fair Trading and NCAT.
