A judge in Wetaskiwin made the ruling following a trial earlier this year for Const. Ron Lavallee.
The 37-year-old was accused of using excessive force during an arrest in Maskwacis on Jan. 1, 2012.
The officer is also appealing an earlier conviction for assault causing bodily harm for a confrontation on Dec. 14, 2011.
Lavallee was sentenced last year to two months in jail.
The RCMP says Lavallee is currently assigned to administrative duties.
