Hi my son as recieved letter from court with intent to prosecute for not having the correct ticket for his journey.
He only had a ticket for part of the journey.
However the details on the paper work have the wrong date of birth and states that he is over 18.
How do I rectify this and can help be prosecuted if he is under 18.
Yes, he can be prosecuted if an offence is evident. As Salesy already correctly identified, the age of criminal responsibility in England is 10 years, but it is not going to be used to deal with a 10 year old in relation to travelling without a correct rail ticket.
The point made by Stigy about 17 year olds is important though.
To bring action in a Magistrates Court the offender would have to be 18 years of age on the date that the plea is heard by the Court. Technically therefore, a person who was 17 years and 7 months old at the time of any offence could be summonsed to a Magistrates Court hearing a week or two after their 18th birthday. That is extremely unlikely to happen in my view, unless a very serious offence is evident and for minor matters, this is likely to be considered an 'abuse of process'.
The company can use Youth Court prosecutions, but rarely do and certainly not for matters such as described by you unless the alleged offender has a history of continuous offending.
If your son is in fact over 17 years of age I'd help him to write and explain what happened in his own words as he was the person there. He should correct the date of birth, sign and date the letter and send it by signed for post. You can include in the envelope a note as an interested parent/third party on a separate sheet of paper if you wish.
IF you don't mind a constructive suggestion, in my long experience of dealing with this sort of thing, letters received in this format tend to get a much more sympathetic and understanding reaction than the more frequent bullish rants that parents / guardians are prone to writing.
If in fact, your son held an invalid ticket and an inspector has genuine belief that an offence is evident, hence the report, the process explained above will allow for this to be sorted out quickly by administrative process rather than Court action.
