The son of Sophie Toscan du Plantier has described the announcement of a full review being carried out into his mother's murder as "very good news for justice".
Speaking on RTÉ's News At One programme, Pierre-Louis Baudey-Vignaud also said his family has "big expectations" from it after waiting over 26 years.
"My family are all deeply involved in the fight for justice of my mother," he said.
Mr Baudey-Vignaud said gardaí called him at around midday yesterday to inform him about the new review.
"I think this new investigation is, in a way, the gardaí recognising there have been some mistakes during the original investigation, and so they need to do a new one," he said.
He added: "Maybe with new technologies, maybe also there are new elements which have been released during these past few months, after my appeal, after the Netflix and Jim Sheridan film.
"So, I am sure if they are launching a new investigation, they think there are new elements".
Mr Baudey-Vignaud said that following his appeal on the Late Late Show in September last year, he did receive contact from people, adding that gardaí received "lots of contacts".
"I am not saying here there are new elements because I am not the person who can say that, but for sure there has been a lot of new contact," he said.
Meanwhile, a former Assistant Garda Commissioner has said "no investigative opportunities have been overlooked" by authorities after the 1996 murder of Ms Toscan du Plantier.
Speaking on RTÉ's Today with Claire Byrne programme, Pat Leahy said that it is important people understand that it is "not a re-investigation of the case" but a formal and independent examination of the investigation being conducted with integrity and objectivity.
He added that it is "a natural process in policing" that reviews would be conducted.
He said the senior investigating officer will be part of the preparation for this, and the review will follow a "very definite process" and that "hundreds of thousands of elements" will have to be reviewed as part of it.
