Fixed penalty notices

[Thomas Ralph]

From the leaflet on fixed penalties

16. DO I HAVE TO PAY THE FIXED PENALTY PAYMENT
ON THE SPOT?
No, you have 21 days to pay the penalty. You are required
by law to provide your full name and address. Failure to
provide the correct details will lead to you being detained
until correct details are given. Failure to provide the correct
details when asked or to give false details is a criminal
offence and can lead to a court appearance and possible
prosecution.

In cases where details given are false or an individual is
abusive or aggressive to staff, authorised members of the
Revenue Protection Unit can detain individuals on Railway
property until their arrest by the Gardai.

Last I checked, nothing in any enactment gives IÉ staff authority to detain anyone. (Dublin Bus inspectors can, though.) Could lead to an interesting case if it ever came up.
