You sound to be having a bit of fun there!. I do not think that the Vice Chairman necessarily acted unlawful. He was in the Chair and if he believed it to be in the best interests of the public to adjourn the meeting to a future time, perhaps to allow tempers to cool, for example, then he had the right to do it. It is the Chair's job to manage the meeting. In such circumstances it might have been prudent to propose adjournment to the remaining councillors and ultimately, I suppose, put it to the vote.
Regarding the Chairman, he must take the chair if present unless he arrived ten or more minutes after the appointed start time for the meeting, in which case the vice-chairman must take the chair. Thereafter, unless your standing orders provide otherwise, the chair for the meeting can only be changed on a resolution of the council (or the occupant of the chair walking out!). In the absence of Chairman and Vice, the meeting must vote another member to the chair.
