Thank you to the Counsel General for confirming the costs. Clearly, the costs wouldn't be met unless there was a failure by the Government to meet the legal requirements with regard to air pollution. I realise that you as Counsel General are not responsible for that side of things, but the sums that you have talked about are more than enough to pay for several air pollution monitoring stations outside schools or hospitals as a contribution towards meeting this legal requirement that has stemmed from that. So, just to make sure that the Welsh Government doesn't face further costs, what steps or what guidance do you use as Counsel General, when you deal with court cases of the kind, to ensure that the Welsh Government either defends itself or yields, or whatever's appropriate, to ensure that the funds spent on these costs don't go on legal cases, but go on getting to grips with air pollution?
