Scotland Bill

I apologise for interrupting my noble friend again, but this is central. For the sake of argument, let us say that this power is used by the Scottish Parliament to introduce a mansion tax or a wealth tax. Is my noble friend saying that this House could consider and reject it and that that is practical politics? It seems to me that part of the 1911 settlement was that this House did not get involved in those matters. In a sense, I am here arguing for more power for the Scottish Parliament, not less, because I think that this has not been thought through.
