I'm agnostic as to whether the ability to review the sufficiency of the list is in the act or the regulations. In the U.K. example I provided, it's actually in the regulations, not the act. For whatever reason, they chose to do that.
I feel strongly that the list itself should remain a regulation. I say this because my colleagues and I have all been at this for a while, and one thing we learned and can tell you is that the evolution of the landscape from 2009, when this power found its way into the law, to where we are now is really quite something. The preoccupations and concerns that we collectively, as a nation, were looking at in 2009 have obviously shifted since that time.
I think the list itself should be left flexible in regulations. I think there should be an ability for Parliament to order some sort of review or a report on the sufficiency of that list. That's the best you can probably do to have the balance of both worlds. You have a list that's flexible and the ability to go back and take a look at it.
