Bailey appeal to hear of criticisms
New evidence highlighting investigatory abuse over the murder of a French film-maker will be presented on the last day of Ian Bailey's extradition appeal.
The fourth and final ground of Bailey's case at the Supreme Court is expected to reveal how Gardai mishandled the investigation following the discovery of Sophie Toscan du Plantier's body in Co Cork in 1996.
The Department of Justice received documents reviewing the investigation last year - 10 years after it was completed.
The documents, which include criticisms of how the investigation was handled, were then passed on to Bailey's lawyers.
The 54-year-old former journalist is challenging a High Court order of his extradition to France, where he is wanted for questioning over the killing, which took place near the victim's holiday home in Schull.
Bailey has always denied any involvement in the murder and has never been prosecuted.
France wishes to exercise extraterritorial jurisdiction to try to prosecute him under its own laws.
But his lawyers have argued during the appeal that France has no right to exercise such authority over Ireland, because if the situation were reversed, Ireland would not be permitted to exercise extraterritorial jurisdiction over France.
Bailey's senior counsel Garrett Simons also argued that Ireland and France exercise extraterritorial jurisdiction in different ways, which would present further problems in adhering to the principle of reciprocity.
Ireland's jurisdiction centres around the citizenship of the accused, while France looks to the citizenship of the victim.
