I believe that suddenly stopping a good decent loving father from seeing their child for no reason at all when that father has been a permanent feature in that child's life since the day they were born is extremely detrimental and damaging to the child and to the parent, and will cause long term damage to both concerned. Also stopping contact from the rest of the child's family for no reason whatsoever who have also  been a permanent feature from the very first day. It is illegal to stop contact from the other parent and the law needs to enforce consequences when this happens.
