Zoom is only permitted for members of the public, so a councillor participating in a meeting by Zoom would have no powers as a councillor. They should not participate in the debate and their vote should not be counted.
The Section 101 motion is poorly worded. A council cannot meet remotely. They could meet as a group of friends, but would have no legal powers. If you delegate to the Proper Officer subject to council consultation, who makes the decision? It's either delegated, or it isn't. What are the statutory obligations of the council? Does that encompass any obligation placed upon the council by statute? In other words, almost everything you do?
