"Forcing the situation where the company will be driverless until another hurried meeting can be arranged.".
That's no big deal. A break of a few months between the old and new boards won't matter much. Nominet's core registry and DNS functoon will continue to work just fine regardless of what's happening (or not) in the boardroom. As proven by the bomb-proof registry service it has provided while Howard and his cronies have been in charge.
Remember that Belgium recently went over a year without a government and the machinery of state - collecting taxes, running an army, keeping the lights on, etc - carried on as normal. If a country can manage for that long without any leadership, I'm sure Nominet could too.
