There is a specific law in the UK requiring production of a ticket to a railway inspector. Doesn't matter if you paid - you are convicted if you are unable to produce a ticket when asked.
Considering that, I'm very surprised this reporter had her conviction quashed - it looks like she broke the law, even if she didn't intend to. (Intent is not required for a conviction for this law).
