The measure of the success is that members attended enthusiastically. Often the debates there are at least as well attended as debates in the main chamber. There are no votes in the alternate chamber. It's not possible to vote, and if the question is opposed it has to be decided in the main chamber. In 15 years, that has never happened, because the business there can possibly be controversial but not necessarily require a decision of the House or a decision of the House on any value.
The debates proceed on an effectively procedural motion that the matter has been considered, and then the debate can take place. It also enjoys a less formal atmosphere than the main chamber. Knowing the size of your current chamber reasonably well, and indeed the one you may be moving to in the West Block, what we have is a room that takes about 60 people in a double horseshoe shape, and it is slightly less oppressive in terms of panelled wood than either our chamber or your chamber. I think that encourages members to take part in a slightly less partisan spirit, but that is also because they sit in a horseshoe shape rather than facing one another, and also because it has a modern feel to it and a less oppositional mode.
