Davey Butorac (BOO'-ter-ack) was convicted of two counts of second-degree murder of two women, whose bodies were found months apart in the B.C. communities of Abbotsford and Langley in 2007.
But the B.C. Court of Appeal overturned those convictions last year and ordered a new trial, while also giving Butorac the opportunity to apply to have the cases heard separately.
The Crown appealed to the Supreme Court of Canada, which has refused to hear the case, effectively upholding the B.C. Appeal Court ruling.
Butorac, who has not yet formally applied to have the cases separated, is scheduled to appear in court next on April 17.
Butorac is also awaiting trial for second-degree murder in the death of Margaret Redford, whose body was found in Langley in May 2006, with the next date in that file also set for April 17.
