That is one arrogant letter.
If the parents are summoned to court and they ask you to assist them because a lawyer is not available, try to highlight several key aspects that have been covered in this material, in Family Care, and the legal volume. For example, is this a true emergency? Is the doctor merely treating a low hematocrit level? It may be pertinent to prove his claim with clinical findings that the infant is lacking oxygen. A review of the medical record may reveal such notations as 'baby active, good color', yet at the same time the doctor may be saying the infant will die if it does not get blood. You may find that the notations have been made in the chart at the last moment before going to trial to show a "drastic change" in the child's condition, despite no real change in any indicator of clinical status, such as low hematocrit, increased bilirubin count, or the baby is now on oxygen in the pediatric ICU. This is the technique used by some doctors to paint a bad picture before going to trial.
So elders now play lawyer in a real court of law, instead of just in a backroom at the Kingdom Hall. Disgusting.
What this paragraph shows is that instead of allowing doctors to do their job, to try to save a life, elders and WT lawyers will waste precious time calling into question the integrity of the doctor, basically calling him a liar and scoundrel. All to enforce their (the WTS's) wishes upon a third party that may not even realize that their life is hanging in the balance. Their chance to live is being put in a precarious situation by uneducated, untrained, inexperienced lay clergy, who do not have the patients interests at heart but the interest of the organization. It's diabolical. If the patient were to die, it's second degree murder.
