No laws broken over alleged porn ring: AFP

A federal police probe into allegations of a porn ring involving Victorian coalition MPs and advisers has found no commonwealth laws were broken.

The probe was initiated after a former government adviser claimed to have organised the sharing of pornography while working for the office of former premier Ted Baillieu.

Victorian Labor, then in opposition, referred the matter to the Australian Federal Police (AFP) to identify whether any commonwealth legislation was breached.

An AFP spokesman said it has evaluated the matter and did not find any offences.

"As a result, the AFP considers the matter finalised," the spokesperson told AAP.

Don Coulson, a former senior adviser to Mr Baillieu, claimed to have organised the sharing of pornography while working for his office.

He is suing the state for $67,000 in redundancy pay he claims he is owed after being sacked for other reasons, days after Dr Napthine became premier in March 2013.

The government is countersuing for $30,000 it says was a severance package he has to repay, because he allegedly stored or viewed a "considerable amount" of pornography in his office.

When the porn ring allegations surfaced last October, then premier Dr Napthine said the government's own legal advice was that the material found in Mr Coulson's office was not illegal.
