[The Deputy Chairman of Committees (Lord Lexden) (Con)]

My Lords, the noble Lord, Lord Randall of Uxbridge, who is next on the list, has withdrawn.

[Lord Trees (CB)]

My Lords, a crucial aspect of the Bill is determining which animals within the vast animal kingdom are sentient. Crucially, of course, that depends on how sentience is defined. The Bill does not attempt to define sentience, and various expert opinions, which I respect, have suggested that that is sensible. But we can be sure that, if and when the Bill becomes law, there will be those who will start to question the limit currently in the Bill or that proposed in Amendment 57, which I support. It is almost certain that at least some scientific opinion will be arguable and credible to propose further extending the range of animals included.

Current definitions of sentience include capacity to have feelings. I know of no way of determining what animals feel, but we know that many lifeforms sense and avoid potentially harmful stimuli, which we do, of course. Although we would sense pain on that occasion, we can only guess at the feeling the animal has, but presumably it is not a pleasurable sensation. Of course it is important to consider the science, but extremely respected scientists can and do differ even when confronted with the same data.

The frontiers of what sentience is will likely shift. I listened yesterday to the evidence given to the EFRA Committee in the other place by Jonathan Birch of the London School of Economics. He is the lead author of the LSE report referred to on the first day of Committee, which has yet to be published but has been carefully considering whether to include cephalopods and decapod crustaceans as sentient beings. Professor Birch commented yesterday with respect to the definition of sentience that the science is evolving. Indeed, the Minister commented in much the same way today.

Clearly it would raise huge issues were more and more animal taxa credibly—and, indeed, scientifically—argued to be sentient. So, although I accept that Amendments 59 and 60 are improvements on the current Bill, I feel that the range of animals included in the Bill should be a political decision determined by the Secretary of State and with the complete and full consideration of Parliament, where the cost-benefit considerations can be properly weighed—taking scientific opinion into account, of course, but not being bound by it.
