Which in the general case is pretty clearly true. If someone is arrested and found not guilty, have their conviction overturned on appeal, etc. they're not in general entitled to payment for lost wages, legal costs, etc. It seems reasonable to consider this a different situation in that it involved a specific fine but I can at least see the counterargument that it's not.
