Ian Bailey's claim of wrongful arrest in connection with the murder of Sophie Toscan du Plantier is back before the High Court today.
The journalist who lives in Schull, Co Cork wants access to Garda files as part of his legal action against the State.
Mr Bailey is suing the Garda Commissioner, the Minister for Justice and the State regarding his arrest here in 1997 and 1998 in connection with the killing of the French film-maker.
He claims that he has suffered severe personal injuries and is seeking damages, for unlawful arrest, false imprisonment, malicious prosecution, assault, battery and trespass to the person.
A decision was made by the DPP not to prosecute following an internal Garda review into his arrest on foot of a statement made by shopkeeper Marie Farrell, which she later withdrew.
Bailey, whose separately fighting an order for his extradition to France, will today push for access to Garda files that he believes will assist his case.
