My impression is only the person performing the C-section was the JW (not necessarily the 'maternity clinic's' owner), and she made a unilateral decision that no-blood transfusion would be performed as she considered administering a BT would be in conflict with her religious beliefs.
The woman who died, was taken to the clinic in an emergency situation due to abdominal pain while only 7-months pregnant.
Perhaps neither she nor her husband had previously met or spoken with the person who performed the C-section, to know that refusal of a BT was even a possibility. It seems, refusal of a BT had not been clearly stated in the documents signed by the patient or patient's husband.
The wording of the husband's statement and Facebook posting, suggested a blood transfusion would have been accepted, if the 'doctor' had made that available.
Was blood even readily available if needed at this unlicensed 'maternity clinic'? Probably not!
