In 1993 the criminal code was amended to provide for the creation of a set of child pornography offenses separate from and in addition to the existing obscenity offenses. Not merely the distribution, but privately possessing or even the making of such material is an offense. It is not enough that the actors or models are over 18, it is an offense to portray them as though they were not. If convicted, defendants face up to 10 years in prison and fines.
Exemptions exist for works with artistic merit or an educational, scientific or medical purpose.
But the law puts the burden of proof on the accused.
