The Yukon Court of Appeal says an inquest into the 2008 death of Raymond Silverfox in Whitehorse was not unfair.
It has overturned a previous ruling that held Yukon coroner Sharon Hanley ran a biased hearing into the death of the aboriginal man in a police holding cell.
An autopsy concluded Silverfox died of a lung infection caused by acute pneumonia.
At the inquest, video tape evidence showed RCMP officers and guards left Silverfox lying on the jail floor in his own vomit and waste for more than 13 hours before he died.
The inquest ruled the death was accidental. The Silverfox family appealed and Yukon chief Justice Ron Veale agreed the inquest was unfair.
That led to an appeal from the coroner's office.
Three judges from the Court of Appeal now say deficiencies noted by Veale were not that serious and the coroner's original ruling should stand. Sharon Hanley retired as coroner in 2012.
