Here's my thoughts on the matter, for what they're worth. I've said it before, the differing opinions on how things should work is the problem. Sometimes there's a right answer, other times, it hasn't been said one way or the other from an 'official source'
Example: There was a thread about how much Senjutsu chakra a person can absorb safely. Initially, lots of people were discussing mathematical formulas for how to determine it; obviously they say there's a set percentage to be.
Me, personally, I believe in differentiating between Senjutsu chakra and Nature Energy. I say that Senjutsu chakra doesn't have the dangers inherent that Nature energy does. I have evidence for why I feel so but, at the same time, that someone could have a differing opinion is perfectly reasonable.
So, Hunter Nin Kakashi is fighting Mizukage Terumi. She uses a Senjutsu Lava Waterfall to which Kakashi absorbs it with his Rinnegan's Preta Path.
Judge A says that Kakashi is turning into stone
Judge B says that his is not turning into stone. Disparity between judges. But usually, only one judge decides and what they say goes.
Different scenario:
Kakashi uses his sharingan to copy the lava waterfall and make his own.
Judge A says ok, it's allowed.
On judges ruling, it's legit. That is all it takes, despite the fact that, since season 1, 'Sharingan can't copy Kekkei Genkai'. It's stated in black and white, but a judge's misguided opinion supercedes canon basis. I've seen it happen before.
Which brings me to the point of my long winded explanation; what really is legit? With so many differing ideas about how things should work, everyone thinks their way is the right way. Obviously, that can't be true but no one ever stops to consider that they might be incorrect. Thus, 'judging' is never going to have any kind of legitimacy. Even with a group of elected officials, there will always be things judge A allows and judge B does not.
