The Supreme Court has been told that new information has come to light in relation to the extradition of Ian Bailey to France that reveals "breathtaking wrongdoing" on the part of state officers.
Mr Bailey is appealing against the High Court's decision to allow his extradition to France in relation to the killing in 1996 of French film maker, Sophie Toscan du Plantier.
Mr Bailey denies any involvement with Ms Toscan du Plantier’s death and the DPP here decided not to prosecute him.
His appeal against his extradition was due to begin on Monday.
This morning, his lawyers told the court that they had received information from two different state bodies that was relevant to the extradition proceedings.
Senior Counsel Martin Giblin said they were forced to bring this material to the attention of the court.
He said it appeared the State had been in possession of information which was highly relevant to the proceedings and to the arguments Mr Bailey's lawyers had made against his extradition in the High Court.
He said submissions in the High Court were very measured, because Mr Bailey's lawyers lacked the evidence which would have enabled them to make stronger submissions relating to Garda misbehaviour in the investigation.
He said the situation was unprecedented and such a situation had never been faced by the courts before. The extent of the wrongdoing by state officers revealed by the documents was breathtaking even by the lowest standards encountered by the courts in past cases.
Mr Giblin said much of the new documentation had been made available to them by the DPP on the advice of the Attorney General.
Some documentation had been received from the Department of Justice yesterday evening. He said the situation was unprecedented as the DPP did not have to make any material available to them, as they had no quarrel with the DPP. He said they believed there must be other documentation.
Lawyers for the State said they were not opposing an adjournment to allow Mr Bailey's lawyers time to examine the documents and to bring an application for the discovery of further documents.
Senior Counsel Robert Barron said the State had not withheld material.
Mr Bailey's lawyers are also expected to bring an application to have what were described as his "very onerous" bail conditions relaxed.
