I am so sorry to interrupt the noble Lord, but he is referring to a previous case in a way which I do not believe is accurate. The example he is citing relates to primary legislation, not to a statutory instrument. An amendment was properly tabled in this House to that primary legislation, and this House voted on it. This House sent the Bill back to the other place in the normal way. The House of Commons decided that it would invoke financial privilege, and that was the end of the matter, so it is wrong for the noble Lord to draw direct comparisons in the way that he is doing.
The reason why the 1911 Act is relevant is that is quite clear that secondary legislation is not covered by some of the conventions that have been raised in debate in this House. What is at risk here is the financial primacy of the Commons.
