Mark Reckless MP has posted at least two updates on his blog and newsletter to the effect that his constituents appear to have been improperly charged PFs, and that he is investigating:

Southeastern do appear to have been charging PFs in these circumstances for at least three years, as per:

I've read the Penalty Fares Regulations, and I do not believe that a PF can be issued merely for being 'off route', as is the case here; furthermore, I consider it reprehensible that Southeastern are using the threat of prosecution to effectively force passengers to pay an invalid PF.
If I were given a PF in these circumstances, I would pay under protest, wait six months, and then sue for the recovery of the difference between the correct excess fare due and the invalid PF extracted under threat of prosecution.
