The B.C. Court of Appeal will rule today on appeals from the lawyers of convicted mass-murderer Robert Pickton and Crown prosecutors.

The appeals were filed in the months following the Port Coquitlam pig farmer’s conviction on six counts of second-degree murder of women from the Downtown Eastside.

Pickton’s lawyers argued that the trial judge erred in his instructions to the jury.

The Crown’s appeal is on Pickton’s acquittal of the first-degree murder charges and the ruling that split the original 26 charges into one group of six counts and another group of 20.

On Dec. 9, 2007, Pickton was found guilty of second-degree murder in the deaths of Sereena Abotsway, Mona Wilson, Andrea Joesbury, Brenda Wolfe, Marnie Frey and Georgina Papin.
