The accused was charged with possession of child pornography collected between 1999 and 2006.
At trial, he admitted the images were child pornography but claimed he collected them for a planned artistic exhibition to raise awareness about child exploitation.
The trial judge acquitted the accused, finding he could rely on the pre-2005 'artistic merit' and 'educational purpose' defences, as well as the post-2005 'legitimate purpose' and 'no undue risk of harm' defence.
The Crown appealed.
The Court of Appeal allowed the appeal, holding that the pre-2005 defences did not apply because the materials themselves lacked artistic or educational merit.
Furthermore, the post-2005 defence did not apply because the accused's possession of thousands of images, stored insecurely over seven years, posed an undue risk of harm to children.
A conviction was substituted.
