It's not that simple.
Imagine your dad who you thought from the day you were born was your dad. Your folks then split up and you have a comfortable life 'cos your dad paid his dues. You might even have a decent relationship.
Then one day that is all taken away because of a DNA test, your dad doesn't want to pay anymore - forget the years when your folks were together and ok, forget the times after when you still saw your dad and it was fun.
I can see the judges point. It was only when the bill was upped did he go and have a test...
