CONVICTED child killer Keli Lane's fight to be retried over the death of her baby girl has returned to the NSW Criminal Court of Appeal.
The former champion water polo player claims the judge presiding over her murder trial in 2010 failed to give the jury the option of considering the lesser charge of manslaughter.
Lane, 38, is serving at least 13 years jail for the murder of her newborn daughter, Tegan, who has not been seen since she left hospital with her mother in 1996.
The hearing continues.
