My understanding is that the wording of the bill would be flexible enough to allow judges to decide that a ceiling of $500,000 is not sufficient in cases where this is done repeatedly, where it is excessive or where it makes no sense. Based on this reasoning, any given organization or individual could be fined, say, $800,000 instead of $500,000. If I understood your answer correctly, the wording of the bill would allow for this kind of flexibility.
