Ian Bailey's eight-day cross examination has come to an end.
The 57-year-old with an address at Schull, Co Cork, is suing the State and Garda Commissioner for his alleged wrongful arrest on suspicion of murdering French film producer Sophie Toscan du Plantier in 1996.
The allegations are denied.
There was a brief but heated exchange earlier as the former journalist expressed his unhappiness at his diaries being used against him in this civil action.
He called it an absolute intrusion of his privacy. When asked to explain one diary entry "smoking a wet day j" he admitted that he used to smoke four to six small joints a day.
He said to some laughter "it was very popular in West Cork. Members of the legal profession used to drive down and road test it."
He is now going to be re-examined by his own barrister.
