Keli Lane's two-day appeal set to start Keli Lane is set to appeal her conviction more than two years after she was jailed for murdering her newborn baby. The former elite water polo player was jailed in 2011 for at least 13 years and five months for the 1996 murder of her two-day-old daughter Tegan. Lane's case will be heard in front of three judges in the NSW Court of Criminal Appeal on Tuesday and Wednesday. The 38-year-old's legal team - lead by barrister Winston Terracini SC - will appeal the conviction on a number of grounds, including that an alternative count of manslaughter should have been open to the jury as there was no evidence "of infliction of any harm with any intent." They are also expected to argue her trial's crown prosecutor, Mark Tedeschi QC, had reversed the onus of proof by posing questions to the jury during his closing address. Lane's appeal comes after Justice Anthony Whealy last year said he wasn't convinced the crown had proved its case. Lane has steadfastly maintained she handed Tegan over to the infant's father, with whom she'd had a brief affair. Tegan's remains have never been found. Lane had two terminations as a teenager and had kept three pregnancies and births secret from family and friends, adopting out two children. The crown contended Lane murdered Tegan because a child would have interfered with her sporting, sex and social life. Earlier this month, Lane's partner Patrick Cogan told Woman's Day that Keli was confident Tegan was alive, but has more than one theory about where the little girl is. Mr Cogan said Lane watched a television report about an Indian boy trying to find his family and said "that is going to be me." She said,'Tegan is going to grow up and have brown eyes and realise that mum and dad don't'. Lane was sentenced to a maximum of 18 years. If her appeal is unsuccessful her earliest release date is in May 2024.
