They may make such ludricrous rulings...but they have no bearing on the facts. A lesbian "partner" cannot couple with, either physically or in the lab, another woman to produce a human child no more than two me could do the same.
It is sick that any nation even has to even have such a discussion and IMHO, the Judges that made this ruling are in need of serious mental help and have no place on any bench...save a physc bench perhaps.
