My Lords, this has been a lengthy and complex debate, and I blame the noble Lord, Lord Anderson of Ipswich, for that; we tried to split this group to make it more manageable, but his will prevailed.
As the noble and learned Lord, Lord Thomas, said, amendments in this group are on prior authorisation by a judge; by an investigatory powers commissioner; by an investigatory powers commissioner unless it is urgent; by an investigatory powers commissioner if a criminal conduct authority is to be used to identify a journalistic source; and by a Secretary of State. Another amendment requires that an investigatory powers commissioner be notified
“as soon as … practicable, and in any event within seven days”
and that the police authority be involved in holding the chief constable to account as a result of the investigatory powers commissioner’s annual report on the use of CCAs.
It is understandable that noble Lords want prior notification—and why the police should not, as the noble Baroness, Lady Kennedy of The Shaws, said, mark their own homework. On the advice of one noble Lord, I read the code of practice that goes with this Bill. I have held both ranks that could grant a criminal conduct authority under this Bill. In urgent cases, that is an inspector, who can not only grant a criminal conduct authority but also grant immunity from prosecution. I was an inspector at the age of 24. I was also, subsequently, a controller of covert human intelligence sources. I spent 18 years as a uniformed officer. On the Friday I left the office as a uniformed chief inspector and on the Monday morning I was a detective chief inspector in the role of a controller. The Government may say that all the people involved in the matters considered by this Bill will be experienced and highly trained, but that is not always the case in my experience.
We should listen very carefully to the noble Baroness, Lady Manningham-Buller, who articulated why prior authorisation is not practical, a point also made by the Minister for Security in another place and by the noble Lord, Lord Anderson of Ipswich. From my experience I agree, although the description of MI5 handlers and agents as beyond reproach is not, in my experience, universally applicable to police handlers and informants.
Any prior authorisation would instruct CHIS to operate within strict parameters, which may no longer be necessary or proportionate once they are deployed, or may not be adequate once they are deployed, because they are being deployed into rapidly changing scenarios in an uncontrolled environment, often involving chaotic individuals. The most common use of CHIS in policing, for example, is to counter drug dealing. As the noble Baroness, Lady Manningham-Buller, has said, you cannot turn an agent on and off like you can a listening device.
Even the most experienced undercover officer may have to necessarily and proportionately go beyond the strict parameters of a CCA because the situation has dramatically changed in ways unforeseen by the handler. If he were to strictly adhere precisely to a CCA, he could put himself in danger of losing his life. As we will hear in later groups, children are increasingly being used as covert human intelligence sources, some of whom have chaotic lifestyles. Sometimes they are drug users or drug dealers. To expect such people to operate within the strict and precise boundaries of a CCA in such turbulent situations is not only unfair
and unreasonable but completely unrealistic. To determine the strict parameters of a CCA to cover every possible scenario, in the middle of a rapidly changing situation, and when the legal immunity of both handler and CHIS depends on it, is unfair and unreasonable to both handler and CHIS.
Those proposing prior authorisation by judges, Investigatory Powers Commissioners and government Ministers may say that any conduct outside the strict parameters of a CCA will be looked at by the prosecuting authorities and a decision made whether to prosecute using the public interest test. In that case, why can the prosecuting authorities not look at all the actions of the CHIS and the handler and decide whether to prosecute?
Amendment 46, for which there seems to be a good deal of support around the House, suggests that the Investigatory Powers Commissioner should be given notice where a person grants a criminal conduct authorisation as soon as practicable and, in any event, within seven days—but, as my noble friend Lady Hamwee and the noble and learned Lord, Lord Thomas, said, so what? What power does the Investigatory Powers Commissioner have to intervene? What happens if the handler corruptly tasks an informant to commit crime? As the authority has already been granted, both CHIS and handler have legal immunity, even if the handler informs the Investigatory Powers Commissioner six days later. A wronged party may be able to claim compensation from an Investigatory Powers Tribunal but criminal offences may have been committed for which the perpetrators should be prosecuted. That is why we have added to Amendment 46, to the effect that legal immunity is dependent on the CCA being approved by the Investigatory Powers Commissioner. If the actions of the handler or the CHIS are not within the limits set out in the Bill, neither are immune from criminal prosecution or from being sued.
I understand completely why noble Lords do not want a criminal conduct authority to be granted without prior judicial or ministerial authorisation because of the potential for abuse. However, as others have said, it is not practical. We believe there is a way to prevent abuse without prior authorisation of a CCA, including protecting journalistic sources, which we will come to in a future group. We have listened very carefully to this debate and have come up with a new amendment; because we were part way through this debate we cannot debate that amendment in this group, but we will come to it in a couple of groups’ time. What must not happen in any circumstances is the granting of legal immunity without judicial oversight. That is what our Amendment 47 attempts to do.
