As regards the phrase "necessary or expedient to do so in the interests of justice", Senators will note that this criterion is already in section 4(3). It also resembles section 17(3) of the Child Care Act, 1991, which was referred to with approval by the Supreme Court in the case to which I referred and which permits an interim care order in respect of a child to be made without notice to a parent where, having regard to the interests of justice or the welfare of the child, the judge so directs.
