All charges have been dropped against Chris Illingworth, the man who was charged for republishing on a video-sharing site a video of a man swinging a baby by its arms like a rag doll.

The move to discontinue the prosecution comes just days after this website revealed that Queensland Police wanted to send Illingworth to jail for up to 20 years on child-abuse charges over a video the Federal Government's own censors had classified MA15+.

It raises questions about the Queensland Police investigation, the legal framework governing child-abuse offences and the decision to charge and prosecute Illingworth in the first place.

A spokeswoman for the Commonwealth Director of Public Prosecutions said: "This prosecution was discontinued yesterday after the matter was reviewed by the CDPP ... taking into account all of the circumstances involved including the classification given to the material by the Classification Board."
