@JimmyT said:It’s not rocket surgery. The chairman is absent (because he hasn’t been elected yet) and the obvious choice to run the meeting until the new chair is elected is the secretary although it could be anybody the meeting chooses. Not even the geniuses at CTTT would uphold a claim that the chairman wasn’t properly elected because there wasn’t a nomination in the motion of vacation of the chair.
If it makes you happy, I’ll repeat my second suggestion that there should be two motions, one to vacate the chair, another to elect a new chairperson. That’s it. Take the legal debate elsewhere if you want to keep going with it.
Thanks Jimmy
