I received a ticket infringement notice in the mail...under brief description of offence it states..UNABLE TO PRODUCE VALID TICKET. Im looking to dispute the offence...i did not have a ticket because the machine at my local station was not accepting notes, only debit card. Now i only had about 10 min to get to work and i knew if i was to tell a ticket inspector i was going to have to wait around untill they could verify my story...which would have taken ages. So i opted to jump the barrier and then the undercover ticket inspectors caught me and the rest is history. Now on my infringement letter it just states unable to produce valid ticket...so i guess im just disputing my reasons for not purchasing a ticket. I've never had a fine before and i buy a full fare ticket everytime i go to work. I jumped the barrier knowing that on my way home i would have needed a ticket anyway, so evading was never an issue. Can anyone shed some light on how to go about writing a dispute letter, or if anyone who has disputed a fine let me know the procedure.
