Hon Deputy Chair, once you are presiding and you have made a ruling, whether the ruling might have been wrong, sitting here as a member I think you are wrong, there is a procedure in the House to deal with it. It's always wrong for us to try to challenge a ruling so that you can review what you have said because you have made a ruling in relation to the very same question and you are still correct. So, let's allow hon Minister to continue with the question and once we get there is then that we can entertain what they are raising.
