Males are probally more than likely to just pay the fine and move on rather than make a major issue. Regardless of RPU actions in general, the ruling in this case for someone sticking her nose in a joke. No wonder insurance costs sky rocker when such foolish decisions are made.
On the subject of fines, I agree some are genuine mistakes. Perhaps IE should consider moving to a system like Luas where the majority get €45 as opposed to €100 fine which is usually at the discretion of the officers issuing the fine. From experience of seeing people on the Luas, more often than not people accept it and there is no attitude issues for the most part where as €100 causes problems.
