Madam Chair, Mr. Therrien raises some interesting points about constitutional law, including Supreme Court precedents. He has explained them well. However, I am not familiar with the specific precedent to which he referred. In any event, I would venture to guess that factors such as geographic representation, communities of interest, and linguistic communities, which are subject to judicial review, are normally taken into account by the electoral boundaries commissions when discussing how to apportion the number of seats according to the formula the Chief Electoral Officer gives them.
I don't think you can extrapolate and establish that this applies, for example, to a minimum threshold of representation that far exceeds demographic weight, as Mr. Turnbull has said.
As I said earlier in response to Mr. Vis's question, Parliament will have this discussion again in 10 years' time, and I suspect they will discuss exactly the same issues.
