If anything causes a problem (with Justice, at least) I think it is this reasoning from Archonus.
The Circle comes first and the circle operates democratically-- Archonus knows that and, being a man of honor, needs to come out and admit that he is in the minority... so, he needs to go along with the wishes of the group.
I realize that he and Xath have a bond different than the Oath. But, if he comes out and says something like this with Justice around-- she will blow up because it implies that you do not trust the group-- and, you have sworn your life ETERNALLY to the group and, as such, if you don't trust it, I would say that you have broken that Oath.
