''Re A (conjoined twins)''
0012 WLR 480
is a
Court of Appeal (England and Wales) decision on the separation of
conjoined twins. The case raised legal and ethical dilemmas. It was ruled it would be permissible to sever and thus kill in a palliative, sympathetic manner the weaker twin to save the much stronger one.
The case was among those where it would be lawful to conduct surgery against the wishes of the parents. The parents' faith was held not to be overriding, nor general applicability of the outcome to all such cases.

on 8 August 2000, were
conjoined twins who were joined at the abdomen.
During legal deliberations, they were given the public pseudonyms "Mary" and "Jodie", respectively.
The medical evidence showed that Gracie was the stronger sibling, sustaining the life of Rosie. Rosie had severe brain damage, very little heart function and no functioning lungs, and survived only due to a shared common artery supplied by Gracie. If surgically separated, Gracie was assessed as having a 94%-99% survival rate, but Rosie was guaranteed to die. If left conjoined, then their life expectancy was estimated to be around six months.

beliefs. They did not consider abortion on learning that the twins were conjoined, and on their birth decided not to separate the girls, even if it meant both would die.
Reasons of judgment and appeal decision
At first instance,
Mr Justice Johnson was left to decide the case without any direct
precedents to bind or guide him.
He relied primarily on ''
Airedale NHS Trust v Bland'' where it was declared acceptable to remove life support. He ruled separation would not be
murder but a case of "passive
euthanasia" in which food and hydration would be withdrawn.
The Court of Appeal agreed in outcome but rejected this analysis. The three appellate judges gave contrasting legal reasoning.
Lord Justice Ward invoked the concept of self-defence suggesting that "If
raciecould speak she would surely protest, ''Stop it,
osie you're killing me.''"
Lord Justice Brooke relied upon ''
R v Dudley and Stephens'' and invoked
necessity as a defence.
Lord Justice Robert Walker focused upon the morally understandable intention of the surgeons, and the great body of profession opinion, in concluding that surgery could go ahead.
Result

The 20-hour-long operation to separate the twins took place on 7 November 2000.
As expected, Gracie survived the operation and Rosie died. Rosie's remains were later buried in her hometown of Xagħra.
In 2014, when Gracie was 14 years old, she was living a reasonably normal life, had a younger sister, and was thinking about studying to become a physician.
In 2020 she was described by surgeon Adrian Bianchi, who had stayed in touch with the family, as "stable, intelligent, independent" and "intent on establishing a professional career".
