My Lords, I am one of those who believe that it is sensible to discuss the content of the Bill, if only because it is a marker, so I should like to return to its substance and talk briefly to the amendments.
If the UK were to leave the EU, it would be the biggest decision that the country had taken for at least 60 years. The idea that its consequence would be a simple retrieval of lost sovereignty is surely ridiculous. The country would have to redefine its place in the world: 60 million people confronting a world of 7 billion. Leaving the EU would not magically open up new markets. The UK would have to go cap in hand to an organisation that it had just spurned to get some kind of trading deal. Its situation would not be at all like that of Norway or Switzerland, which did not join the EU in the first place and were able to tailor deals at an early stage.
That is the backdrop to my support for many of the amendments tabled to the Bill, including Amendment 50. A referendum result that is, in the terms of the amendment, “definitive and beyond challenge”, is absolutely necessary, and all means must be pursued to ensure that it is achieved. There could easily be protracted legal challenges if the Bill is not thought through in all its ramifications—for example, challenges to the extent of the franchise. Many further amendments are relevant to that point.
I have studied referendums all around the world in the course of my academic work and I feel that Amendment 56 is also essential. I lived for quite a few years in California, where the problematic aspects of referendums were very visible. It is vital to insist on a baseline turnout for a referendum of any importance, otherwise decisions, even highly consequential ones, can be taken that do not reflect the will of the people. A minimum of 40% turnout is therefore to me an absolute exigency.
