Mr Finkelstein recommended in his government-commissioned review of the media industry earlier this year that the self-regulatory Australian Press Council should be overhauled in line with the ABC model.
But two decisions this week reveal the APC is tougher on commentators who compare opponents with pedophiles.
On Tuesday, The Australian reported that the ABC had dismissed a complaint by its former chairman, Maurice Newman, against science broadcaster Robyn Williams, who made a comparison between climate change deniers and pedophiles last month. An ABC spokeswoman said the complaint was dismissed because the editorial context of the segment was reasonable, meaning "harm and offence" was justified.
Today, The Australian publishes an adjudication by the APC about an opinion article in the newspaper by the libertarian conservative commentator James Delingpole about the Australian wind-farm industry.
The article quoted an unnamed sheep farmer who said that the "wind-farm business is bloody well near a pedophile ring. They're f . . king our families and knowingly doing so."
The APC upheld the complaint, concluding that because pedophilia was a "very serious and odious crime" the comments were "highly offensive".
"The council's principles relate, of course, to whether something is acceptable journalistic practice, not whether it is unlawful," the adjudication says.
"They are breached where, as in this case, the level of offensiveness is so high that it outweighs the very strong public interest in freedom of speech. It was fully justifiable in the public interest to convey the intensity of feeling by some opponents of wind farms but that goal did not require quoting the reference to pedophilia."
Two other complaints about the Delingpole piece published on May 3 were also upheld by the APC, however several others were denied on the basis they were "not of a kind on which the council could make a decision".
Mr Finkelstein declined to comment on how the regulatory body he decided needed to be overhauled had been harder on such a similar issue than the ABC's own complaints process.
Newman had complained to ABC boss Mark Scott that Williams had failed the broadcaster's "public interest" test.
During a November 24 broadcast of The Science Show, Williams said: "What if I told you that pedophilia is good for children, or that smoking crack is a normal part and a healthy one of teenage life, to be encouraged? You'd rightly find it outrageous. But there have been similar statements coming out of inexpert mouths again and again in recent times, distorting the science."
An ABC spokeswoman again defended its decision when asked if the APC adjudication meant the ABC might review it. "The ABC acknowledges there are climate scientists who question the core thinking about climate science. The ABC gives them . . . air time. The weight of our coverage, however, rests with the weight of the broad consensus, focusing on the extent of the impact of climate change and the speed and nature of human interventions required in response."
