Well, the concern would be, as a lot of people have said, that in operational circumstances there may have been intervention by the chain of command—but we don't know—and it hasn't been regulated. The point is that Parliament will say that if this has to happen, this is how you do it.
There's one really important point I'd like to make in addition, sir. It doesn't specify with exactitude exactly when this power could be invoked, because the point is that one doesn't know. Ultimately you can't legislate integrity or common sense, but as a very brief and apt quotation that I'd like to share with you, Professor Llewelyn Jones Edward, in his publication about the attorney general, said:I am convinced that, no matter how entrenched constitutional safeguards may be, in the final analysis it is the strength of character, personal integrity and depth of commitment to the principles of independence and the impartial representation of the public interest, on the part of holders of the office of the Attorney General, which is of supreme importance.
The goal of this is for Parliament to give as much statutory guidance and protection as it can, but the bottom line in reality, sir, is that you have to choose very carefully the people you appoint and that you have to rely on their integrity.
