The transport working group for Bramley Moore stadium is Led by Everton Football club, in conjuction with the Council and Merseyrail/Merseytravel etc. That has been the case throughout the process, from consultation, planning and throughout the build. If the council or any of the other groups responsible have reneged or failed to deliver any infrastructure or resources that was agreed at planning or any point since, then the club could have highlighted this publically. As far as I know, they haven't, so we can only assume that the club agreed with the adequacy of provision, as laid out in their planning application and included transport plan. There is nothing new as regards planned matchday transport arrangements. There was always going to be major parking restrictions given the nature of the site, and the operational capacity of Sandhills and the Shuttle buses were all laid out in the transport strategy, and have always been known.
As a comparison, both Spurs and Arsenal had to contribute to major new infrastructure costs as part of their planning processes. That was their agreement to allow their projects to get planning, and this is ours. So blaming a cash-strapped council is pointless, unless it can be shown that they failed to deliver on anything agreed. If that can be shown, then club can hold them accountable.
However, it was clear from the start that there was always an obvious massive disparity between the "required" and "actual" public transport capacity at this site. The transport plan clearly stated that it would require a reversal in the current proportions of public to private transport usage at GP.... which roughly equates to 32k+ using public transport/walking at BMD (compared to only 15k currently at Goodison). Transport modelling obviously showed that allowing cars into the immediate vicinity would only grid lock the available lanes required for public transport and the shuttle buses..... and the transport plan basically descends into Shank's Pony, with the saving grace of the city centre with all of its transport hubs and capacity. I believe there are potential solutions to improve that connection with the city centre and elsewhere etc.... but none are really covered in the transport plan which was (porposely) vague from the start.
One thing that whole debate has at least brought to light in recent years, is the high number of potential Olympic speedwalking champions there are amongst our fanbase.
