The appellant sought to strike his guilty plea to possession of a loaded restricted firearm, alleging material non-disclosure.
The Crown had requested an adjournment of a Charter motion, citing a police officer's medical unavailability.
Fresh evidence revealed the officer was facing criminal charges, which were not disclosed to the defence.
The appellant asserted he would not have pleaded guilty if aware of these charges.
The Crown conceded the fresh evidence's admissibility, the material non-disclosure, and that it likely influenced the plea.
The Court of Appeal accepted these concessions, allowed the appeal, set aside the guilty plea, and ordered a new trial.
