Spokesman Neil MacKenzie says that although the Crown asked for three to nine months of jail time for Monty Robinson, it can't identify any error in law that would justify an appeal of the one-year conditional sentence.
MacKenzie says the Crown would not be able to persuasively argue that the sentence handed to Robinson last month was unfit because the judge considered factors such as the ex-Mountie's deliberate and calculated misconduct and his position of public trust.
Robinson is currently serving a month of house arrest for his role in the October 2008 death of Orion Hutchinson.
After the crash, Robinson went home and downed two shots of vodka and later said he'd tried to calm his nerves but a judge found he'd attempted to mask the effects of alcohol he'd consumed earlier that night.
Robinson still faces perjury charges in connection with his testimony at the public inquiry into Polish immigrant Robert Dziekanski's death after he was stunned by an RCMP Taser at Vancouver's airport in 2007.
