The Office of the Rail Regulator has ruled that there is no case to
answer with regard to the London Travel Users Council's complaint
concerning the timing of FCC's evening restrictions ending at 19.01
thereby excluding 19.00 departures by both MML and GNER but not by FCC
who do not have any trains departing at that time.Can anybody refer me
to a copy of that adjudication in the public domain? In dealing with
this the ORR are obliged to function in accordance with rules laid down
by the Office of Fair Trading who have concurrent jurisdiction - see
the OFT guidance notes above. In particular the OFT are hot upon the
operation of cartels that put in appropriate barriers by raising
switching costs - recently they drummed the banks for putting
bureaucratic delay barriers in the way of people switching accounts.
The OFT can compel the production of documents - a process known as
discovery. It would be interesting to know if FCC, MML and GNER did any
point liaise over the timing of the end of the restrictions.
