I guess so, unless you can justify in some meaningful way why the court can make such a decision. Your post only said they could weigh the evidence to render a decision regarding guardianship. It did not say what evidence was weighed and how these judges arrived at their decision, so for the layman, your answer falls way short of the mark of explaining their action. And you expect others to simply agree?
Sorry, but I'm not really sure what you want me to explain to you. Moreover, I fear that anything I do say that you disagree with will merely be dismissed as "legalistic crap."
