The late Scott Douglas Routley had a nasty road traffic accident around the turn of the century, which damaged his brain. By 2012, Scott had been comatose, persistently vegetative, “locked-in” – or however you want to put it – for 12 years. He couldn’t move, or talk.
Scott suffered from a “prolonged disorder of consciousness” (PDOC). Scott was therefore fed and watered by means of “clinically assisted nutrition and hydration” (CANH). In that respect, Scott’s condition was similar to that of the late Alfie Evans, about whose death I am presently trying to take the coroner to court, over his refusal to hold an inquest.
A few days ago, the UK’s Supreme Court ruled in An NHS Trust & Ors v Y & Anor  UKSC 46 that there was no need for hospitals to continue pestering the courts, whenever they wanted to get rid of somebody with PDOC by withdrawing his CANH, causing him to die of thirst whilst possibly beginning to feel a bit hungry too if he wasn’t asleep for the duration.
The Supreme Court explained that the Common Law said the hospitals should just get on with the euthanasia concerned, without bothering their lordships, unless the patient’s stubborn family, for example his parents, couldn’t be dissuaded from objecting to this proposed economy. That, reportedly, was the gist. You can read more scholarly and neutrally-worded summaries than mine of the case, which I will abbreviate as NHS v Y (and #NHSvY on Twitter), both here and here.
