Although we don't know the full details of the custody agreement, this is an unusual case that will be looked upon favourably by all fathers fighting for equal rights and access rights to their children. I acknowledge that the father in this case was married to the childrens mother which leaves him in a stronger position then a single father.
There are so many stories of "bad fathers" and fathers who do not care, it's great to read about a ruling of this type.
