Today in the NSW Supreme Court, Senator Hanson's legal representatives discontinued proceedings against the ABC and she was ordered to pay the national broadcaster's legal fees.

Last week, Senator Hanson launched the legal action against the ABC and former party treasurer Ian Nelson to stop more covert recordings being broadcast.

Senator Hanson succeeded in temporarily gagging Mr Nelson and proceedings against him are continuing.

The injunction followed a story by the ABC's 7.30 program which revealed a secretly recorded phone conversation between Senator Hanson and Mr Nelson where Senator Hanson appeared worried the alleged donation of a light aircraft would become public, months before it became a controversy.

Ms Hanson has denied breaching electoral laws by not disclosing the plane and strongly disputes Mr Nelson's version of events.

Mr Nelson told The Guardian last week he has more than 4,000 secret recordings but in an affidavit presented to the court said that was an exaggerated figure.

"Whilst I have publically [sic] stated that I had over 4,000 recordings, this figure was embellished and I do not have 4,000 recordings of Pauline Hanson or other One Nation conversations with Party Office Bearers," the statement reads.

Mr Nelson now says he has deleted all but one recording of Senator Hanson, which is solely in the possession of his solicitor Michelle Harrington.

The barrister representing Senator Hanson, Dauid Sibtain, argued before the court that if Mr Nelson had deleted the recordings after legal proceedings had begun it would amount to the destruction of evidence and potentially contempt of court.

Today Judge Francois Kunc ordered that Mr Nelson produce his phone, computers and storage devices for expert inspection to prove he had in fact deleted the recordings.

"My client welcomes the opportunity to provide his devices to the expert so that his honesty can be assessed. He will cooperate in all respects," Mr Nelson's barrister James Cremin told the court.

An injunction against Mr Nelson continues until the matter returns to court in August.
