The family successfully sued on the grounds that after an incident where the boy ran away from the group on an outing the leaders wanted additional support for him for travelling on a bus, athletics activities etc. The boy and his family felt that the additional support would make him stand out and was effectively banning him from these activities.
I see this from both sides: of course any parent wants their child to be able to join in the maximum of his abilities in all the activities. Scouting should be making that happen for anyone who wants to join and gets a place. As a volunteer myself (albeit in Guiding rather than Scouting) I would want to ensure the safety of the child and the group as a whole. If I felt that some activities were triggers I would be talking to the parents to come up with a strategy and putting extra support in place if I felt it was necessary for the safety of the group overall.
What I don't understand, and isn't made clear from the article, is why 42K was awarded. It's a hell of a lot of money from a charity because they couldn't accommodate him as the parents wanted in a club.
