I still believe your best avenue is by negotiations and friendship with your alleged father. I thought DNA can never accurately prove paternity, only disprove paternity.
I just read your post again. You say you are an illegitimate child. The law recognises you as such, probably by your birth certificate, so where is the unlawful interference? In what way have you been illegally deprived? I cannot see how you claim to have fulfilled the UN stuff you wrote.
As for stolen generations of the Family Court, they are persons whose parents were known, but did not get to be raised by both of them. In the forgotten generations, they were persons whose birth certificates had been altered due to a particular event, later found to be unlawful,or done in mistake,and rectification sometimes made, or original birth certificate given to them.
You do not seem to me to be in either category. Perhaps the gentleman is not your biological father, just a father figure.
Sorry, I can't assist further.
