Thank you for the question, sir.
I can lean on my own experience here to say that there are doctors and there are doctors. Just as there are judges and there are judges, there are doctors and there are doctors, and when you aren't able to find medication or obtain medication from one doctor, you are often able to find it from another doctor. That's why you “doctor-shop”.
The protection of having a superior court justice is that it is someone who is removed from the situation of the physician, someone who can weigh the law and the affidavits of physicians and the competing evidence from family members and make an informed and legal determination. There is no doubt that sometimes judges get the answer wrong, but it seems to me that as far as ethical considerations go, it is far better to have the matter in the hands of a judge than in the hands of a physician.
