Northern Ireland (Executive Formation and Exercise of Functions) Bill

I just want to be clear in my mind about what the Secretary of State is saying. I understand she is saying that there will be no change in policy and decisions will be made by civil servants in the Departments without changing policy. What happens when, in the absence of an Assembly and an Executive, there is a challenge to the policy—perhaps for being in breach of our international obligations? What happens then to the policy? Who is responsible then for dealing with that?
