Mr. Speaker, I believe that your interpretation of the rule, as I saw it being dispensed, is quite correct. There are two different concepts here. The first is that one may not ask a question of a previous minister or a minister who is no longer responsible. That is in citation 410 of Beauchesne's.
However, it is also equally true that the government itself can decide that any minister can answer a question. That is not the same proposition; it is a totally different one. The two of them are very different and the Speaker was quite correct in giving a different decision in both cases because they are different propositions.
