When CASA is wrong
When CASA is wrong they will firstly never admit anything. Secondly they will close all ranks. Thirdly they will engage the target and commence attack mode.
If you wish to engage in any defence the only avenue is the court system.
From experience unless you have several $x,000,000 to waste / fight CASA it is not worth your health. You are fighting a bureaucracy that is largely self serving and corrupt.
This is why GA is almost dead. The only way to live with CASA is to pay them off (not literally of course) but those that play know how it works.
Your $2M house, your privacy, your friends/family your physical and mental health is not worth the fight
