A team of French forensic investigators are to travel to Ireland to examine evidence gathered by gardaí investigating the murder of Sophie Toscan du Plantier.
Minister for Justice Dermot Ahern agreed to allow the team to travel here after receiving a written request during the summer from the French magistrate Judge Patrick Gachon.
A spokesperson at the Department of Justice said that the State has already provided French authorities with written evidence.
The spokesperson said French investigators will be allowed to examine non-testimonial, non-written, physical evidence when they arrive here, but no evidence will leave the State.
The body of the 39-year-old film producer was found outside her holiday home in Toormore near Schull in Co Cork in December 1996.
