Justice Kevin Duggan, and six months later on 17 December 1990, Justice Duggan released his findings. He ordered von Einem to stand trial; however, he expressed concerns with most of the prosecution's evidence. The pre-trial hearing began on 19 December 1990, in the Supreme Court of South Australia, with Justice Duggan as the presiding judge. The prosecution decided after Justice Duggan's findings two days earlier to have von Einem tried separately for the murders of Barnes and Langley. Justice Duggan ruled that the evidence relating to the Kelvin murder, and from the various associates of von Einem and hitchhikers, was inadmissible. Justice Duggan did rule that "Mr B"'s evidence could be heard, but that the defence would be allowed to question the evidence as it was being given. This was a shattering blow for the prosecution's case, and on 21 December 1990, on advice from the Attorney-General of South Australia, prosecutors withdrew the charge for the murder of Langley. The prosecution tried to continue with the charge for the murder of Barnes; however, with the problems associated of getting enough evidence admitted into court from associates about von Einem picking up hitchhikers, the final charge was withdrawn on 1 February 1991. The prosecution, on the advice of the Attorney-General, then entered a nolle prosequi for the Barnes murder charge.
