Convicted baby killer Keli Lane has lost a bail application ahead of her appeal in the New South Wales Supreme Court.
Lane's appeal against her conviction for murdering her newborn baby Tegan includes the ground that the jury should have been directed to reach a verdict on an alternate charge of manslaughter.
The baby was last seen leaving Auburn Hospital two days after being born in September 1996.
In 2011 Lane was convicted of Tegan's murder and was jailed for at least 13 years and five months with a maximum sentence of 18 years.
The 37-year-old former champion water polo player will be eligible for parole in May 2023.
During her trial in 2010, the jury heard Lane had five secret pregnancies, including two terminations and two children she adopted out.
Neither the man or Tegan have ever been found.
When the jury found Lane guilty of murder after a week of deliberations there were dramatic scenes in court when she fainted and an ambulance was called.
In sentencing, Justice Anthony Whealy said she murdered Tegan 'in a situation of desperation' and felt that she could not turn to people close to her for help.
Justice Whealy also said the case was "a tragedy involving mother and daughter" and that the life of a defenceless baby had been taken.
Lane was not in court for her bail application this morning but appeared via video link from a Sydney jail.
She was dressed in prison greens with her once-blonde hair now dark and pulled back in a tight bun.
Lane also appeared to have lost weight since she last appeared in court.
Lane's barrister Winston Terracini SC argued for her to be granted bail ahead of her appeal hearing.
He told the court the evidence used to convict her was circumstantial and he also criticised the conduct of Crown Prosecutor Mark Tedeschi.
But Justice Clifton Hoeben refused Lane bail ahead of the appeal.
He told the court he'll give his reasons for the refusal at midday tomorrow.
On the video screen, Lane sat with her head in her hands as the decision was read out.
Her appeal will be heard in July.
