Data Retention and Investigatory Powers Bill

I simply ask the Minister whether he accepts—he has more or less done so—that there is a risk that the sort of principles that were applied in the case of the Merchant Shipping Act could apply to the Bill as drafted, and that the only way of dealing with that would be to employ the “notwithstanding” formula to ensure that the Bill actually survives for the reasons of terrorism, national security, child pornography and child abuse that were properly mentioned earlier. Does he accept that what I am proposing is effectively to sustain the provisions of this domestic enactment and that I am not just making a general speech about the sovereignty of the UK Parliament?
