Indeed. I suspect, as this was some months ago, there was little progress on their complaint. Here's my understanding for
@Gray. They're right to point out that introducing a fast-track lane for MMST holders appears to be a technical breach of clause (5) of the Manchester City matchday season ticket terms. That clause clearly states MMST holders have "no precedence over other passengers," which implies a general equality in the experience facilitated by the ticket.
However, as someone who doesn't hold an MMST, they're not a direct party to that specific contract. While the Contracts (Rights of Third Parties) Act 1999
could allow them to enforce a term intended to benefit them, it's a very high bar. Practically speaking, if they were to sue for damages, proving quantifiable financial loss from a few minutes' delay would be incredibly difficult, likely resulting in only nominal damages, if any.
Alternatively,
@Gray could apply for an injunction to force the closure of the fast track, but courts are generally reluctant to intervene in commercial operations for minor inconveniences. Moreover, the most likely first response from Manchester City and Transport for Greater Manchester would be to revise the terms and conditions to explicitly allow for a fast track, which they are legally entitled to do.
