I'm no slouch on Robert's Rules. If the temporary chair never even elected a chairman, the meeting can never have really gotten started. Who, then, was the secretary, and how could minutes have been officially recorded? Clearly, there was no qualified parliamentarian who was consulted. While I have seen a motion to suspend the rules pass, immediately followed by a motion to adjourn carried when meeting topics got uncomfortable and a convention went on well past the passage of necessary business (in Missouri), the way this was conducted sounds like a pure mockery. . . until serious participants reconvened outside and completed the agenda.
