The simplest solution it to put a motion on the agenda – and do it right now – that proposes that each item in the new by-laws be discussed and voted on individually.
You could add in an explanatory note that while most issues will go through without debate, there is a small number of contentious issues about which there are strong feelings. Failure to discuss and vote on these individually could result in a successful challenge at NCAT over what amounts to a denial of vote. That would lead to the rejection of all the by-laws, resulting in the need for another EGM.
“All or nothing” is no way to revise the by-laws of a building.
But I repeat, send your motion in now with the request that it be attached to the agenda of the by-laws EGM. Motions must be included on the agenda for the next general meeting if they are submitted before the agenda is issued
