The Legislature placed on DCPP the burden of proving by a preponderance of the evidence that a parent abused or neglected a child, N.J.S.A. 9:6-8.46(b)(1), and the Judiciary has no commission to exercise equitable powers to alter the statutory burden of proof set forth by the Legislature. The Court disapproves of the Appellate Division cases that have imported the doctrine of conditional res ipsa loquitur from the common law into a comprehensive statutory scheme to relieve DCPP of its burden of proving that a particular parent abused or neglected a child. The Court remands for a new hearing.
