The fact that the relevant authorities haven't made a clear ruling in the current cases has made it much more difficult for individuals to do the right thing.
Nail on the head. In all of this stuff, it's the authorities that are failing the most.
There is a need to say "no" to individuals for the greater good, and often their own good too, and it can be very hard for someone close to the individual to do that.
Having an external authority that will straightforwardly say "no" can save an awful lot of relationship stress by avoiding a fight with parents/guardians/others. That close person isn't put into the position of having to be the only gatekeeper.
This is the problem with the second Keira Bell ruling - it's potentially putting parents into that gatekeeper position again. TBH, I reckon a lot of doctors would really rather have such a near-total ban that they're not put into that position of saying "no" either.
A huge number of people left the Tavistock, apparently mostly because they felt unable to get system back-up for their "no"s.
