A Saskatoon man who was convicted of killing his wife appealed his conviction in a Regina courtroom on Tuesday.

David Woods was found guilty of first-degree murder in the death of Dorothy Woods in 2014. Court heard that he hit her over the head, knocking her out, before strangling her in 2011. Her body was found in a culvert near Blackstrap in early 2012.

Woods was sentenced to life in prison with no parole eligibility for 25 years after his conviction.

His appeal was originally scheduled for last summer, but has been adjourned twice.

In a rare move, the media was granted permission to film the appeal. CTV News carried the feed live on our website.

Woods is questioning the judge’s decision to allow certain evidence to be heard, as well as the judge’s instructions to the jury. He is also taking issue with his lawyer’s effectiveness at his trial in 2014.

“The instruction isn’t that they should not consider all the evidence, the instruction is problematic because it has them draw conclusions first, before considering all the evidence,” James Streeton, Woods’ defence lawyer said at the hearing.

The evidence brought into question was a series of threatening text messages allegedly sent by Woods to a man he believed his wife was having an affair with.

In the original trial, court heard the couple both had affairs, and that Dorothy was looking to end the marriage.

The defence argued that because the messages weren’t sent to the victim, they shouldn’t have been used to show Woods’ disposition towards his wife. They also argued Wood’s defence lawyer during the trial, Michael Nolin, didn’t properly cross examine several witnesses.

The Crown disagreed with all points made for an appeal by the defence, but Crown Prosecutor Alan McIntyre said Nolin did the best he could under the circumstances.

“[Nolin] had a case that was difficult from the outset, facing overwhelming evidence, and in my respectful submission, a very good job,” McIntyre said before Court of Appeal.

In an unsurprising move, the three justices overseeing the appeal elected to reserve their decision.

“We’ll deliberate on this matter, and render a written decision as soon as we reasonably can,” Chief Justice Robert Richards said to end Tuesday’s appeal submissions.

There’s no timeline on when the Judges’ decision will be released.

In the meantime, Woods will continue serving his life sentence.
