WA's highest court has dismissed an appeal by a former private girls school chaplain jailed for possessing child pornography.
In March, Matthew David O'Meara was sentenced to 15 months prison after being found guilty of possessing hundreds of images and videos.
The images and videos were found on two computer thumb drives in his possession.
At the time, he was the chaplain at Perth College in Mount Lawley.
O'Meara denied any knowledge of the material and suggested at his trial that he may have been set up.
He has always maintained his innocence but today the Court of Appeal rejected his submission that his conviction was a miscarriage of justice.
O'Meara still has a couple of months to serve before he can be released on parole.
