I put this question to our shaykh, ‘Abd ar-Rahmaan al-Barraak (may Allah preserve him) and he said:
Reference should be made concerning that to specialists. The issue should be put to a medical committee, and if they determine that what this doctor did was wrong, then he must offer expiation and pay the diyah (blood money) to the male heirs of the deceased.
But if they say that the doctor did not do anything but what was required of him, and there was no error in what he did, then he does not have to do anything. End quote.
You have to refer this matter to the administration to take the necessary steps to form a specialist committee that can examine the matter, as is usual in such cases.
And Allah knows best.
