Relatives of Schapelle Corby are suing an author and publisher for defamation over a book about the convicted drug smuggler's father.
Mercedes, Rosalie Rose and Michael Corby are suing the author and publisher of Sins Of The Father, saying it implies they were involved in Mick Corby's drug operations.
Lawyers for Allen & Unwin and author Eamon Duff are in Sydney's Supreme Court today arguing the book makes it clear that no-one played a role in Mick Corby's drug operations other than Schapelle Corby, when she took marijuana to Bali.
Allen & Unwin lawyer Sandy Cameron says the book states that Mick Corby's drug deals were conducted away from the family home at a car park at Jupiters Casino.
Mr Cameron also told the court the book made no suggestion of regular contact between Mick and Rosalie Corby, saying it makes clear the marital separation took place in 1979 before his foray into drug smuggling.
