Ian Bailey’s lawyers have begun their appeal against his failed legal action in relation to the investigation into Sophie Toscan du Plantier’s death.

He claimed he was wrongfully arrested twice and unsuccessfully argued there was a Garda conspiracy to frame him for her murder.

The majority of his grounds of appeal relate to rulings made by the trial judge over the course of the 64-day hearing.

Mr Bailey arrived at the Four Courts with his partner Jules Thomas at 9.30am this morning – an hour before his appeal got underway.

In his civil action, he unsuccessfully argued that his arrests following Sophie Toscan du Plantier’s murder in west Cork in 1996 were unlawful.

Following a trial, the jury dismissed his claims that he was the victim of a Garda conspiracy to implicate him in her murder.

His lawyers have submitted over 30 grounds of appeal. Most of them relate to various rulings made by the trial judge.

He contends that the decision not to put certain allegations to the jury was wrong.

They have also raised issues about the narrowness of the conspiracy claims eventually put to the jurors.

The hearing is expected to take two days.
