The family of Maria Altagracia Dorval is seeking just over $683,000 in damages, after the 28-year-old was stabbed to death in her Montreal North home.
Dorval's relatives say they want to be compensated because they believe the Montreal police should have done more to prevent the young woman's death.
Dorval was murdered on Oct. 17, 2010, after she had recently separated from her husband Edens Kenol.
She filed complaints against Kenol with police in the weeks before her murder.
The police ethics committee absolved 5 Montreal police officers of any negligence in Dorval's death.
Kenol was convicted of first-degree murder and is serving a life sentence – although he is appealing his conviction.
The family has been fighting in the courts for years.
Their first lawsuit, dating back to February 2012 against the city of Montreal, sought $905,000 in damages.
Their second lawsuit was filed in October 2013, this time seeking damages for just over $683 000.
After losing, the family filed an appeal, which was eventually dismissed.
Despite all those setbacks, Dorval's family is now seeking a reversal to the judge`s decision to deny their appeal.
