Admissibility of evidence taken on previous proceeding
9In considering any application brought under this Act, the court, upon notice to the parties, may allow to be read into the record as evidence, or, upon notice of the nature of the evidence, may take into consideration without reading into the record, any evidence taken on any previous proceeding, if that evidence is informative in any way as to the psychical, psychological, social or physical development of the child, his parent or any other person living with the child or in such a close relationship with the child as to be in a position to influence the nature of the care and control exercised with respect to the child, and if it is relevant to any matter under consideration by the court.
