As for the judgment, Judge Walker would be pretty stupid if he wrote one which reeks of bias. Of course you can't tell from the judgment itself. But that, as I said, is beside the point. Actual bias need not be shown. As long as a reasonable member of the public perceives that there might be bias, the judgment must be set aside. So in answer to the question posed by this thread, I would say: There is no evidence Judge Walker was biased, but, even so, if there the mere perception of bias in the minds of the public, his judgment cannot stand.
