The appellant challenged orders dismissing his civil action arising from alleged new home construction defects and declaring him a vexatious litigant.
The Court of Appeal held that the motion judge misconstrued both the pleading and the statutory scheme under the Ontario New Home Warranties Plan Act by treating the action as a prohibited relitigation of matters already determined by the Tribunal.
Relying on the distinction between Tarion decisions, Tribunal determinations, and surviving civil warranty claims, the court concluded that the pleaded claims related to defects found warranted and were not fully barred by issue estoppel, res judicata, or abuse of process.
The vexatious litigant order was also set aside because it was premised on the erroneous view that the Superior Court action itself was vexatious.
Leave to amend was granted only to the extent previously contemplated for the appellant's own claims, and no costs of the appeal were ordered.
