Going against a parent's wishes is hugely destructive. Taking a legal course of action to lawfully force parents to allow grandparents to see grandchildren against parent's wishes destroys families. Some AC might be spiteful, sure, but like someone else said NOT all grandparents are whiter than white. To force a another person to go to court and make them give you access to their child is to take money, resources and time from the people who are taking care of that child you're meant to care about all for your own benefit. Some grandparents are wronged for sure, however some grandparents prefer to try everything except just being nice to the parents of the child. There may be instances of sexual, emotional or physical abuse, neglect, absent grandparents, absent parents to AC, racisit, unfit caregivers, appalling judgement, a huge threat of parental alienation "oh mummy and daddy are SO awful to us, we love you so much, mummy and daddy are mean, grandma loves you, you should live with grandma, grandma loves you the most, mummy and daddy tried to keep grandma away but she loves you more than anyone, mummy and daddy are awful and nasty to grandma"
There really is a whole host of reasons why people stop you seeing their children. They want family time, just want to live their own lives, maybe you're overbearing. Who knows. You got to make the decisions exclusively when you raised your children however and now you don't like the outcome want a blanket law to FORCE parents to give up their right to parent their children and forcefully insert yourself into the picture. What good outcome is that going to be? Tense mum and dad not wanting to sent child to court ordered access? Tense parents not wanting to communicate to the people who dragged them to court and are taking their kid against their will for a few hours on the weekend? Looking the people in the eye that would rather take money and resources from their children and trying to lay out guidelines for the visit? Will they be allowed to speak up? Do they have to forfeit their rights as parents in other ways? Can they ask you not to feed child xyz or take child to xyz?
Its a slippery slope. None of the above stuff is creating a happy, secure home life for the child. The child will know mum and dad dislikes grandma or grandpa, but every week they have to go to a contact centre and see grandma anyway. They come home and the atmosphere is naturally tense because the courts have taken away a decision that should be solely made by the parents.
Too many variables. Hence why the law currently gives no automatic visitation because its up the parents to decide who gets to be in their children's lives. Dragging them to court because you think your relationship with your grandchildren is the MOST important thing in your grandkid's lives is so self absorbed, deluded and naïve. As is thinking they'll be NO negative knock on effect to the grandchild. It all has to be weighed and balanced.
