The Minister would have a veto on any change. There would have to be complete agreement of all eurozone Ministers to any change that might happen, and whoever the Minister for Finance might be in three, four or six years' time would be able to veto any decision which might have a negative impact on the State. The Minister would not be able to enter into any decision that might incur an additional cost to the Exchequer without the approval of the Oireachtas. A change to the resolution waterfall which might change rates and incur an additional cost would not be able to be agreed.
