On the face of it, the setup for the meeting looks wrong. At the start of a new council year, the annual meeting of the council is held.
When the meeting starts, it should be chaired by the previous year's chairman, or failing that, the previous year's vice chairman. The meeting proceeds swiftly to the election of a new chairman (who could be the past year's chairman) at which point, the newly elected chairman takes over the meeting, first signing the declaration of acceptance of office.
So it's not clear on what basis a councillor who is not the past chairman came to conduct the election of the new chairman, in the presence of the past chairman.
