My Lords, although I sympathise with Amendment 79, which seeks to protect those who act genuinely in the public interest, I do not support it, for a number of reasons.
First, although I accept that, in its comprehensive 2020 review relating to the protection of official data, the Law Commission recommended that a public interest defence be introduced, that was in relation only to the Official Secrets Act 1989. Its recommendation did not suggest that such a defence should be incorporated into the rest of the Official Secrets Act regime, which is what in effect this Bill seeks to replace.
Secondly, in any event, the risks of introducing such a defence need to be carefully considered and balanced against the benefits of potential alternative approaches. This includes the creation of an independent
commissioner to receive and investigate complaints of serious wrongdoing, which the Law Commission also recommended.
Thirdly, any introduction of a public interest defence needs to form part of a wholesale reform of the Official Secrets Act 1989, which this Bill does not seek to do. As I said at Second Reading, the ISC was disappointed to see that the Government were not reforming that Act. I will not repeat what I said then, other than to say that it is a very significant missed opportunity. That is particularly so because the Government have accepted the need to change the OSA for years, and this Bill represented a clear legislative route to do it.
Lastly, this amendment is very broadly drafted. It would introduce a public interest defence into a range of offences that do not require one, such as the offence of assisting a foreign intelligence service. For those reasons, I cannot support it.
