The courts should double the fine every time a guilty company appeals. The idea being to dissuade the practice of using appeals to 'fish' for a favourable result, or continually appealing because it buys time for inflation to eat away at the real value of the fine (ie. keep appealing until €210 mil is about the price of a beer at the pub).
There are good arguments why courts should not do what I'm suggesting but I'm over companies trying to buy the answer they want.
