I am grateful to the noble Lord for his work on the ISC. He is absolutely right: The Principles, published today, will lead to internal guidance being produced by the MoD, for example, which will take the overarching principles and turn them into more specific guidance relevant to the context in which people in the MoD will work. That internal guidance will be available to the IPCO. I will take advice on whether it will also be available to the ISC; I see no reason why it would not. Sir Adrian is minded to encourage, where possible, this internal guidance being made public.
I have discovered the right paragraph for my noble friend Lord Deben. I refer him to the section called “Reporting non-compliance” in Sir Adrian’s report. On not reporting any non-compliance, it says:
“Non-compliance for these purposes is a failure to comply with these Principles. An instance where a sustainable assessment, made in good faith, subsequently proves to be incorrect will not count as an incident of non-compliance”.
That is the serious section of The Principles that addresses my noble friend’s point, which I have now located.
