My Lords, I acknowledge the changes that have been made to Amendment 79 since it was introduced in Committee, but I still do not feel that it would be appropriate and right for us to accept it. The noble Lord, Lord West, has pointed out a number of the reasons why, but I emphasise that we are being invited to introduce a public interest defence for what is, straightforwardly, espionage on behalf of a foreign service. I do not believe that we need to provide a public interest defence when an individual obtains and provides protected information on behalf of a foreign power while recognising that this is prejudicial to the safety of the United Kingdom.
I also recognise that the amendment extends to the Official Secrets Act 1989 but, again in support of the noble Lord, Lord West, I say that, if we are to change that, we must do so in a careful and deliberate fashion and bring forward legislation to do so. The 1989 Act does not deal with espionage on behalf of a foreign intelligence service. It is drawn up for different purposes. Therefore, it is separate from the issues that we are considering regarding the Bill. More broadly, it remains extremely dangerous to encourage or to lead individuals to believe that there is a public interest defence to the disclosure of highly sensitive information. Any one individual is unlikely to be able to make an accurate assessment themselves of whether their declaration
and their disclosure is damaging to national security. That must be considered carefully, and it is not something for an individual official, however senior, to take on themselves. Therefore, any legislation and any amendment that might encourage them to do so is misguided.
Also, once a disclosure has been made, it cannot be withdrawn. Even though there may be benefit in prosecuting an individual for having done it, that does not stop the damage that has already been done. Therefore, we must have care not to lead people into believing they will be able to defend themselves having already made a disclosure, because the damage will have occurred.
Finally, on the question of evidencing damage, I recognise that the change in the burden of proof is a significant change to the amendment. Nevertheless, we are then faced with a situation where a person who has been accused of this offence will be trying to argue that they did not cause damage. In so doing, they are likely to adduce more evidence and more contextual material which might itself be damaging. It is not clear that this makes it easier in terms of the evidence or that it makes the prospect of prosecuting people for harmful activity any easier. For these reasons, I do not support this amendment. I hope that the House agrees.
