A Saskatoon judge has decided not to re-open the trial of Douglas Hales for new evidence.

Hales’ defence submitted an application last week to re-open the trial, arguing a recent Supreme Court decision changed the burden of proof in the case and that the defence should be allowed to bring in more experts to testify.

Defence lawyer Bob Hrycan wanted court to order a psychological assessment of Hales and stated Hales’ potential cognitive issues need to be considered by the court when it comes to the reliability of his confession to undercover RCMP officers.

Justice Gerald Allbright said he’d rule on the defence’s request sometime before Nov. 14, and on Thursday he stated he would not be re-opening the trial.

Hales is accused of killing Daleen Bosse, a 25-year-old mother who was last seen in 2004 and whose body was found four years later in a rural area outside Saskatoon.

Hales confessed to the murder during a so-called Mr. Big sting in which undercover RCMP officers posed as members of a fake crime ring.

Allbright was set to rule on the case in August but a Supreme Court ruling stalled the decision.

The Supreme Court, in July, set requirements for the admissibility of evidence obtained during Mr. Big stings.

The defence pushed for a mistrial but Allbright dismissed the request, ruling last month the trial would continue.

Final arguments in the case will be heard Nov. 14, according to defence lawyer Hrycan.
