Director of Public Prosecutions Jon White called in police last week over material provided to Victorian Magistrate Peter Lauritsen, who was in Canberra to preside over a two-day hearing.

Details of that case cannot be published for legal reasons.

Prosecutors aborted last week's court proceedings in front of Mr Lauritsen after the Melbourne magistrate revealed that he had been sent a detailed background briefing on the case.

In a submission to the court, Mr White's office alleged that a bundle of documents had been sent by email to the visiting magistrate, which included the case against the accused, matters for consideration in the hearing, relevant case law and a copy of the existing suppression order preventing the media from reporting details in the case.

The Chief Magistrate, who is due to retire on December 15 after a 34-year career on the magistrates' bench, confirmed that ACT Policing detectives had executed a search warrant on his chambers on Monday, a move he described as unnecessary.

''I am aware that a search warrant has been executed and I'll just make it clear that had I been approached I would have said that there's no need for a search warrant if you want to search my chambers because I have nothing to hide,'' he said.

''The document is there, it's on the public email.''

Mr Cahill said what he had done was ''completely transparent''.

''... I have never hidden what I did and it's just unfortunate that this publicity had to happen without me saying that I clearly believe that I have done nothing wrong,'' he said.

''I will fight to make sure that the character damage done to me by this publicity is rectified.''

Earlier, Mr Cahill told ABC Canberra's 666 breakfast program that after speaking to Mr Corbell he was ''amazed that we've had any publicity at all''.

''... I thought there'd be no further comment because I've asked and requested and he's acceded to the desire that I put it all in writing, which I'm endeavouring and working on just at the moment in what spare time I have,'' he said.

''... In my view any publicity at this stage and the inferences that are being raised are totally regrettable,'' he told presenter Ross Solly.

Asked whether what he had done was normal practice, Mr Cahill said, ''... This is not a normal case. It's related to a visiting magistrate, so we don't have any normal practice.

''But I must say, of course, that this is not a case of me influencing a magistrate at all, it's a case of doing what I thought was appropriate to assist in making the case run appropriately.''

Mr Corbell held a doorstop press conference on Tuesday.

Asked then whether a judicial inquiry would be held, Mr Corbell said, ''These are all matters which are under consideration, I'm not going to speculate further on that except to say that I will make further announcements in due course.''
