If the government were to announce new appropriations or new budgetary expenditures that exceed the limit, it would need to request a new budget limit. To do so, it would need to go through the whole process. That's how the system allows for more transparency, as I said. If the government wants to spend more and the limit becomes restrictive, it will need to be transparent and ask Parliament to raise the limit.
