A Denver police officer’s 30-day suspension has been overturned after a Civil Service Commission hearing officer determined the city used the wrong use-of-force standard in the case.

The Denver Department of Public Safety made an erroneous decision when it suspended Officer Choice Johnson for 30 days, hearing officer Terry Tomsick wrote Tuesday in a decision letter.

Daelene Mix, safety department spokeswoman, said the city will appeal the hearing officer’s decision.

In July 2014, Johnson was working off-duty in LoDo when he shoved bar patron Brandon Schreiber, causing him to fall. Schreiber was at his brother’s bachelor party.

Schreiber was charged with interference and resisting arrest. He filed a complaint against Johnson and reported being choked and slammed to the ground. A city surveillance camera captured the confrontation.

In March, Deputy Director of Public Safety Jess Vigil found Johnson used inappropriate force because Schreiber was not a credible threat. Tomsic, though, ruled Johnson used non-deadly force, which was appropriate.
