You mentioned 50/50. The other poster mentioned 99 percent. Maybe something in between would not be problematic? Ninety percent approval? I'll acknowledge that we are of course just talking about red flags here at most.
As an aside, I'd imagine that in previous days without these public advocates, the government would have bent over backwards in choosing submissions judiciously, to guard against the obvious perception that the court was being abused. But now perceptions are different, and they can (from a PR standpoint) afford a very small amount of fighting with the public advocates. So maybe now they'll push the envelope a very slight bit, see where the boundaries are.
