This sure doesn’t look too optimistic, though as you said who knows what happened between then and the time he actually did leave this mortal coil (also, was this lawyer putting the muscle on him at the time?)
ADL would show more character if they said they firmly disagreed with honoring a man with a sanctuary funeral under such circumstances, and then left it. After you’ve said what God would presumably have to say, what else is there to say? ADL has unfortunately gotten whiny in many cases and that’s a shame. It undermines their credibility.
If you’d like to be on or off, please FR mail me.

Another thread which discusses the Vatican's position and refusal.
Rome debates funeral for Nazi war criminal (Roman Vicariate says "No")
As to those suggesting or questioning whether he repented, both his statements during life and his release after death, the proper question would be what sins. He did nothing wrong, just followed orders, and the Holocaust is largely a myth anyway. The ovens were kitchens as we all know. I can see how this would be a problem for the Vatican.
