And here is another case
http://www.penmansedgwick.com/PracticeAreas/Criminal/FareEvasion/FareEvasionCases.aspx (which I provided assistance for)
The defendant was accused of over-travelling without paying the correct fare, and I am certain that if they had not had proper representation the court would have found in favour of FCC. In fact the defendant had done nothing wrong. FCC were very worried by the presence of defence solicitors as it threatened to disrupt the day they had planned with many cases to get through, all of which were just rubber stamping exercises.
It has taken months for a forum member to get acceptance by GWR that they held a valid ticket for a journey made in April, and this was only after intervention of the retailer, and after numerous staff members (all of whom would no doubt be treated as expert witnesses by a court!) all stated the OP's fare was not valid.
I think some people really have absolutely no idea what goes on! Come and join us at a forum meal some time and I'll tell you what goes on!
