The Crown appealed from a stay entered after a trial judge held that issue estoppel barred relitigation of possession of cocaine, based on a prior dismissal of a conditional sentence order revocation allegation.
The Court of Appeal held that, although the revocation judge had effectively decided the possession issue in the accused's favour, the revocation ruling was not a final decision capable of grounding issue estoppel in a subsequent criminal trial.
Revocation proceedings are sentencing proceedings, not trials determining guilt for a new offence, and extending issue estoppel to them would be inconsistent with the narrow criminal-law scope of the doctrine and its underlying policy objectives.
The appeal was allowed, the stay set aside, and a new trial ordered on the possession for the purpose of trafficking count.
