And that statement, if it is indeed the basis for the court's ruling, exposes the utter hypocrisy of their earlier ruling in favor of same-sex "marriages". The earlier ruling was based on the bizarre notion that gender isn't a significant enough factor for marriage laws to take notice of. And yet, biological relation, which is inherently based on gender (it's the whole reason for gender in the first place), is still given special notice.
In other words, if the judges involved support same-sex marriage, then they have some explaining to do.
