The Crown has filed its appeal in the Ray Newman case, seeking to overturn pre-trial rulings that had excluded nearly all of the evidence.

Newman was found not guilty last week on a charge of second-degree murder in the death of his estranged wife Chrissy Predham Newman in 2007.

The Crown says Supreme Court Justice James Adams made mistakes in acquitting Newman.

In a series of six pre-trial rulings, Adams excoriated the police for “egregious” violations of Newman’s rights.

But the Crown argues that Adams was wrong on several points.

The Crown says the judge erred in ruling Newman’s statement to police the night of the murder was inadmissible.

The appeal also contends Adams was wrong when he ruled that Newman's right to remain silent had been breached, and was wrong in his interpretation of a Supreme Court of Canada ruling on evidence.

The Crown also believes the judge was mistaken in law in finding there was an unreasonable search and seizure under the Charter of Rights and Freedoms.

Adams ruled that the warrants the police had obtained to search Newman's car and home were invalid because the police had violated his rights during the initial interview.

Chrissy Predham Newman's body was found in her Airport Heights apartment in January 2007. She had been stabbed, and her throat had been slit.

The Crown has yet to file its arguments on the appeal.

Newman's lawyers can then file a response.
