That still kinda' seems like a monumental undertaking. There are 196 countries, so even trying to figure out what the law/rules are for a small portion of them would be quite the task.
Reasons we shouldn't try and get change;
1/ It's how we've always done it.
2/ It'll be too hard.
3/ It's easier just to complain.
4/ ....
On a side note I am working to get the law/system changed around the family court to ensure less children lives are destroyed. I am not interested in fighting the Family Court. I am interested in changing the system. This is a monumental undertaking that will likely take decades. I've set up a charitable trust for it. One primary concern is widespread perjury by parents. Perjury is illegal. The Family Court has no jurisdiction to deal with perjury associated with a Family Court case. The Judge has to accept that people are telling the truth and that their lawyers are not supporting perjury. Perjury is a criminal matter that requires a Police investigation and then further the Police then have to decide to charge the person and the court process be run for that. What this means is children lives get destroyed and some years later if the system deems it appropriate perjury charges will be laid. In New Zealand the Police to my knowledge have not charged on Perjury in this environment and therefore it means you can tell massive lies and get away with harming children.
I've had person after person from the Ministry of Justice, The Courts, The Human Rights Body, The Childrens Commissioner tell me it an't be changed. That the processes go back to the British Westminster system. I tell them I know that but the reality is children lives are being destroyed and we have two choices. Do nothing. Do something. The courts are by and large operating correctly. The problem is the systems and processes need changing.
I hope to see that change in my lifetime. It's unconscionable to me that we allow this to exist. I am aware that resources and work needed to make this change though. It is big.
