Thank you, Mr. Minister.
In terms of the first part of your question of why it's not in the act at the moment, if you go back 30 years, at the time it was not envisaged that the service would be as involved as it is today in administrative proceedings or criminal prosecutions. The threat has evolved, and terrorism is taking a growing place.
I think it is pretty obvious why we need to protect our sources. We've talked about it in terms of nobody wanting to cooperate with us if they were putting their life at risk. But I think it's also very important that we shouldn't lose sight that when somebody is cooperating with the service quite often at the risk of their own security and with the promise of confidentiality, the state has a duty to protect that person and to protect their identity so that we can protect their security—and not just protect them but sometimes their family also.
We have to balance that in different proceedings with how we maintain fair proceedings. I think the bill has achieved that balance.
