Why offer cash incentive to establish a principle?
The Italian government was ordered by the same court to pay €5,000 compensation to the woman who found the crucifixes so disturbing in the first place. While I can understand someone taking a case on a point of principle, it is a grave error to add a financial incentive for doing so.
I think we can safely assume there will be many more cases taken in the future and not a few of them with their eye on the cash prize for getting it through the court system successfully.
