Armed Forces Bill

Debate between Lord Houghton of Richmond and Lord Craig of Radley

Committee stage
Monday 8th November 2021 Grand Committee

[Lord Houghton of Richmond (CB)]

My Lords, it is a pleasure to speak in support of this amendment. It is one of the few elements of the Bill that seeks to get ahead of the game rather than just play catch-up. My particular perspective is that there is one element of the new security challenge that I feel has escaped proper consideration, one for which there seems no comprehensive or coherent plan of action, which is the issue most commonly referred to as “lawfare”.

To my view, the law is potentially one the most powerful weapons that we have in the security context of the age. It is both a weapon of defence that we should use to protect ourselves from the malign activity of others, and a weapon of attack that we should use to liberate our own freedom of action. As had been said, a fundamental deduction from the recent integrated review was that, within what is a significantly changed strategic context, we now live in a persistent state of adversarial competition, but one in which the resort to formalised warfare at scale is, perhaps by choice, avoided. The preferred vectors of attack in this competitive world are not, therefore, active, large-scale military operations, but more subtle, more deniable and less attributable activities.

The domains of active warfare are no longer necessarily primarily land, sea and air, but space, cyber and what is called the “cognitive domain”. Whereas traditional warfare has rules and laws and accepted norms of ethics and morality, the new character of grey-zone warfare is one in which our enemies exploit, for advantage, the absence of a legal framework within which to operate. So the new vectors of attack are activities such as disinformation, multiplied by internet bots; deniable cyber offensive activity; proxy terrorism; and political assassination, potentially using international private military companies.

More specifically in relation to this amendment, technological advancement in the areas of artificial intelligence, machine learning and autonomous weapons systems also offers scope for our adversaries to deny us their potential benefit while they exploit their unattributed use simply because no accepted legal framework for their authorised use yet exists. This context means that our principal geopolitical adversaries can employ methods that are both malign and aggressive but which we find difficult to respond to because we are unclear about what is morally, ethically and legally permissible. We risk, in effect, allowing our enemies to win without fighting.

In this House, during the passage of the overseas operations Bill, I bore witness to—forgive me—some remarkably contorted debates that appeared to present the law as either something inviolate to change or else an irremovable object that needed elegant methods of circumnavigation. I fear that our enemies will exploit our legal complexities to undermine our morale and devalue our credibility as an ally, among other things.

My view is that the only practical way to respond to the situation I have described and the one described in the integrated review is to start to use the law to our advantage: to go on the legal offensive, to reimagine our use of the law not as a time-honoured constraint on activity but as a weapon to be employed to liberate and confirm the legal boundaries of our own freedom of action while bringing much-needed constraint to the malign activities of our enemies. The Government need to give serious thought as to what aspects of this legal offensive need prioritisation. This House, consisting as it does of far more legal minds the military ones, has a significant role to play, but unless global Britain can make a meaningful contribution to the re-establishment of internationally accepted norms of morality, truth and justice, some might seriously undermine the willingness of our people to fight for them.

My strong view is that this country has all the necessary skills to embark on lawfare. I hope that, within their stated intent to help shape the future international order, the Government have the political will to do so as well. I believe the amendment is a small step in the right direction and it has my unreserved support.

[Lord Craig of Radley (CB)]

My Lords, I support this amendment and agree that there is an increasing need for clarity not just today but in the immediate future about the legality of, for example, remote aerial vehicle kinetic operations that involve loss of life, whether military, paramilitary or civilian. Many recent operations have been conducted on an asymmetric footing and not all perhaps with formal, clear-cut international approval. Of course, the right to self-defence is well understood, but how confident are we that emerging technologies in defence weapons systems and their oversight will remain invariably with a human in ultimate control? How it that to be maintained in order to comply with the present laws of conflict as new weapons systems with new technologies are deployed? Are the laws of conflict being overtaken by the possibilities of new types of lethal weapons systems?

Presumably the legality of a remote aerial vehicle operation applies to long-distance control from ships as well as to that from a land base that is remote geographically from the target. Does that base have to be on national territory? What if it is not? What if the operation of the remote vehicle is shared with an ally? How has the operation been approved? What justifications are required for an armed response or for initiating one?

What if the child of a non-combatant civilian accidentally killed by a remote kinetic strike subsequently grows up and seeks to sue the individual or individuals responsible for the control or authorisation of the attack that killed their parent? Will the loss or destruction of any official records of the attack be any sort of viable defence?

As technology moves defence capabilities forward, we will soon enter the era of loyal wingman UAVs and how they interact with their human control. Swarming mini drones are also emerging. There will soon be more, as novel digital technologies are exploited; for example, in the Tempest programme, although I do not have knowledge of secret projects.

The Armed Forces personnel—and this is the key point—involved in kinetic operations exploiting these novel technologies must have absolute clarity about the legal position in which they are required to operate. It is time to know more about how the Government are examining this issue, as I am sure they must be. It is time to be kept informed about the considerations of this complex legal issue as it evolves. Reports from the Secretary of State to Parliament are a must. A review, which should be already in hand, should be reported to Parliament.
