It's something that all governments, to my recollection, have done. It's nothing new.
What was surprising in the fall economic statement was the number of spending items that were contained in one of the annexes. This annex listed all the spending items that had been taken or decisions made after the budget and before the fall economic statement. The list was quite long. For me, who follows government spending rather closely, I saw items there that I had never heard about. There were items there from decisions that were made on spending outside of the budget and fall statement normal cycle.
It's not an issue in and of itself. Governments need to have that flexibility to make government announcements or funding decisions as they see fit. But the number of these measures suggests that the budget was not a firm, solid government spending plan if a couple of weeks or very few months after there were already a number of additional spending decisions that had to be made.
It begs the question as to what the purpose of a budget is if a couple of weeks afterwards there are already new items appearing on the radar screen for new government expenditures.
