The judge cannot be considered unbiased. Citing feminists that think all sex is rape, claiming in the past that "Marriage, in the legal sense only, is a purchase. The buyer is the man, who commits himself for the rest of his life to provide food, shelter, clothing and medical attention in return for... the exclusive use of his bride's vagina.", that law does not support women enough, etc. He's also been known to commit judicial misconduct in the past by altering transcripts.
Perhaps he wanted to be known as the noble chivalrous judge who protected womyn against the evil rape culture. After all, womyn are always innocent and men are always guilty.
We already know that courts are heavily biased against men, be it child custody, divorces or the sentencing gap (men have 62% longer sentences even after controlling for other factors http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2144002).I guess now they want to make it so that a woman's testimony counts for more than a man's; sort of like the opposite as in Sharia where a man's testimony counts for twice as much as a woman's.
