But it would need still be JUDICIAL discretion, not Kidicial discretion! THAT is black and white - a judge, not a kid DECIDES what will be.
That's absolutely true, but its also a judge that decides whether or not to give any weight to the child's wishes.
There was a case in my state a couple of years ago that really hits that home with me....because a judge truly listened to the child. The child was 12.
Legally, neither mom or dad were unfit...there were some relatively minor issues in both homes, but neither one were unfit from a legal standpoint. Dad had received custody because mom moved (two hours away to where her parents lived) and then a couple of years after that dad allowed the child to move to mom's temporarily because of tension between his wife and the child....but didn't change custody legally.
The child wanted to stay with mom, and dad wanted the child to return to him, and it went to court. No GAL was involved or any other court professional. The judge decided to hear what the child had to say in chambers.
The child was a basket case about the whole thing but was suddenly extremely calm and relaxed after speaking to the judge in chambers (the judge kicked the attorneys out). All she would tell either of her parents was that the judge "ordered" her not to tell either of her parents about their conversation.
The judge's order was that the child remain with mom, because the child articulated very mature and logical reasons for wanting to stay with mom. Afterwards the child did confess that the judge told her that he was going to let her stay with mom, but that she wasn't allowed to "tell".
That's not the only time that I know of situations where a judge chose to listen to a child in chambers, with or without attorneys present, and went with the child's wishes. However my state is one of those ones where the child has no "legal" option to express a preference. Its totally up to the descretion of a judge to decide whether or not to take the child's wishes into consideration.
The point I am making is that judges do decide sometimes to listen to children, and that doesn't necessarily mean that the children have to "testify". That does not mean that the children get to choose, it only means that sometimes a judge will seriously consider a child's wishes, based on how the child expresses themselves.
