I thank my noble friend for that correction—yes, it was Ponting, not Westland. I apologise; I had the wrong incident in my mind.
My fourth point is about the life sentence contained in subsection (3) of the proposed new clause. I simply do not like tautologies such as “manifestly unjust” in criminal sentencing provisions. In my view, if there is to be a provision of this kind—we have been told that it has been drafted very carefully—it should not contain tautologous phrases like that. “Unjust” will do very nicely, as far as I am concerned.
My fifth point is about the authority for such a prosecution. The noble Lord, Lord Bethell, referred to the involvement, presumably, of the Director of Public Prosecutions in authorising such a prosecution. However, as drafted, this proposed new clause would permit a private prosecution, which could be stopped by the Director of Public Prosecutions only in certain circumstances. Private prosecutions—often justifiably—are becoming more fashionable and frequent, particularly in fraud cases which the authorities are not able to undertake for reasons of scale and cost. Those are perfectly defensible private prosecutions, as results in the courts have shown. However, the use of private prosecutions for oblique motives in this context seems to be a very realistic possibility. I therefore urge that if we are to have a revised treason offence, it should be prosecutable only with the authority of the Attorney-General.
Finally, the House should pay very close attention—I would say this, as a former Independent Reviewer of Terrorism Legislation—to the views of Jonathan Hall KC, who has considered this matter in detail and with whom I agree. I also simply pose a rhetorical question: who seriously thinks that ISIS would be discouraged in any way whatsoever by the introduction of this clause? The Government are right in the decision they have taken, and I hope that they will stick to their view.
