'Simpsons porn' user loses appeal against child pornography conviction

A man charged over cartoons showing sex acts involving children modelled on The Simpsons characters has failed to have his child pornography convictions overturned.

In the NSW Supreme Court on Monday, Justice Michael Adams ruled a fictional cartoon character was a "person" within the meaning of the relevant state and Commonwealth laws.

In February, Alan John McEwan was convicted in Parramatta Local Court of possessing child pornography and using his computer to access child pornography.

"The alleged pornography comprised a series of cartoons depicting figures modelled on members of the television animated series The Simpsons," the judge said.

The cartoons showed characters like Bart, Lisa and Maggie Simpson having sex.

The man was convicted and fined $3,000 and placed on a good behaviour bond.
