VANCOUVER -- A rookie Vancouver police officer who admitted abusing his authority when he pushed a disabled woman to the ground has been suspended for six days.

Const. Taylor Robinson was captured on video shoving Sandy Davidsen, who has multiple sclerosis and cerebral palsy, as he walked along a sidewalk in the Downtown Eastside in June 2010.

Robinson's lawyer has argued that his client's actions involved an innocent lapse of judgment and that a two-day suspension was sufficient, though Davidsen's lawyer sought 15 days.

The officer has received the punishment after a disciplinary hearing last month by the Office of the Police Complaint Commissioner.

Adjudicator Wally Oppal says the facts are not in dispute and notes the length of time it's taken to settle the matter is unacceptable.

Robinson's lawyer has said Davidsen incorrectly believed his client tried to grab his firearm, though the officer has admitted to using unnecessary force.
