The appellant was charged with failing to comply with orders under the Building Code Act requiring him to obtain building permits or remove structures.
At trial, he argued he had obtained permits for some buildings and no permits were required for others.
The appeal judge convicted him, finding these defences were impermissible collateral attacks on the orders.
The Court of Appeal allowed the appeal in part, holding that arguing compliance (having permits) is not a collateral attack, restoring those acquittals.
However, arguing no permits were required is an impermissible collateral attack, so those convictions were upheld.
