I can't help but wonder why it isn't immediate - or did they create a new Bylaw for it that requires process to repeal? If they did, they could just state they won't enforce it from now on.
The working group said it should be "by" 2nd June" rather than "on" 2nd June.
In any case, ScotRail's MD already confirmed on 29th April that they don't (and can't) enforce the ban (see post #55) and it is routinely ignored anyway.
AFAIK, there was never any bylaw amendment made, so there is nothing to repeal.
The on-board announcements about the "ban" were becoming less and less frequent over the years and I assume they have now been stopped.
