Let me make a couple of preliminary points, before handing it over.
Obviously, the sanctions that are passed by the UN Security Council have the agreement of the members of the Security Council, including the permanent members. That happens in a context. Those are then implemented under the UN Act. If the situation under consideration involves one of the UN Security Council's permanent members, obviously we're in a different political context. I think that's where the government has other instruments available to it to take action, and that's where, as Hugh had set out before, SEMA has been used in those kinds of contexts. That's where we look at the suite of tools that have been used to deal with a particular context.
