We have had similar lengthy discussions on a similar matter HERE. when an owner and her non-owner lawyer sister would both attend meetings and both speak in an effort to harangue the committee
Agreeing on standing orders that limited speakers to one voice per vote worked, up to a point – that point being when the owner became so distressed she was offered the opportunity to step outside and compose herself, which she did … then complained she had been excluded from the meeting! People! What can you do?
But it’s worth looking at the whole standing orders thing if this is an issue for your scheme. Just search “standing orders” (use the magnifying glass symbol at the top of your screen) and you’ll get pages of valuable insights.
