A court case where in reality there was no risk to the carers because this goes on all the time and has done for years and no one really cares?
The judgment lays out the special circumstances very clearly.
The man in question has the well-articulated desire to have sex and lacks the capacity to arrange it for himself which is why he would need to request that a carer arranges the matter and the practicalities. A risk assessment needs to be done both for the adult and the sex worker.
I've quoted it before (maybe the Nordic model thread) but Hayden remarked on reports from care teams that they find it helpful to facilitate sex for some young men with brain injuries whose behaviour is very challenging. Again, questions of capacity would apply concerning their ability to book appropriate transactions.
we cannot hold someone with a disability to a higher moral standard to someone who is non-disabled.
Hayden's potted history of legal instruments to deny sex to adults with learning disabilities etc. was eye-opening. He also gave a very clear history of the considerations of abuse, vulnerability, and exploitation for affected adults. Hayden also acknowledged that there is a distressing rate of institutional abuse of such adults.
As balloonsandboobies and PPs highlight, it is other factors that are relevant.
