Certainly there are a number of mixed models and multiple accountability mechanisms in a number of different jurisdictions. Not having done a comprehensive survey across the OECD or across the United Nations, I think we are an outlier by currently having very weak parliamentary oversight. This committee's hands are essentially tied in a number of ways, when it should be one of the most robust ones.
As I mentioned, these services, by necessity, operate in the shadows. They have to. However, they have to become accountable, because the powers they have are significant and could be abused. That accountability to Parliament needs to be augmented as well as possible.
