FIVE Law Lords are to rule in a case involving the death of a prisoner in New Hall women's jail at Flockton.
They will decide whether an inquest jury should have been able to blame the Prison Service for the death.
Lawyers for Home Secretary David Blunkett have urged the Law Lords to overturn two court rulings that coroners are bound by human rights laws to allow juries to make public findings of neglect or fault on the part of prison authorities.
Sheena Creamer, 22, was found dead at New Hall while on remand for dishonesty.
A coroner, although concerned that a prison doctor did not recognise that Creamer was at risk, did not give the jury the chance to add a rider to its suicide verdict, indicating that neglect contributed to her death.
The verdict was later overturned by a higher court.
A new inquest was ordered after it was held that the restriction on what could be recorded in a jury's verdict broke the European Convention on Human Rights.
