Gerard Baden-Clay did not appear at the Queensland Supreme Court on Friday morning for the continuance of his bail hearing, during which his counsel argued against evidence of blood found in the family car.

Baden-Clay, accused of killing his wife Allison and interfering with a corpse, was in the courtroom on Thursday, but the hearing was cut short due to a security threat.

Allison Baden-Clay's blood found in family car?

Peter Davis SC, counsel for Mr Baden-Clay, argued it was only a luminol test, and not Allison's blood. He further argued that the only injury forensics found in Allison's body was a chipped tooth. He pointed out there was no reason for blood to be in the car when there was no other report on Allison's injuries.

For his part, prosecutor Danny Boyle argued the Crown did not need to provide evidence at this time to show the blood found was indeed Allison's blood.

The defence for the accused: Lack of evidence

Davis also used the lack of concrete findings in arguing for Baden-Clay's bail. He said there was no report on the cause of Allison's death. Police also had no evidence to prove Allison's husband had been at Kholo Creek, where her body was found ten days after she went missing.

While there were previous reports on sightings of the car similar to the Baden-Clay family car, the reports remained inconclusive. Davis went on to say police had no evidence on Allison's time of death.

Bail for the children

The police said Baden-Clay could interfere with potential witnesses if his bail is approved.

Davis argued his client must care for his children, and should therefore have bail. He also said the father of three young girls currently have no existing valid passport.

Security scare in the Baden-Clay hearing

The Herald Sun reported Thursday's hearing was dismissed five minutes into the session after a security threat was phoned in.

"It's absolutely disgraceful, if this is a hoax, that the proceedings of the state's highest court can be disrupted in this dreadful way," Chief Justice Paul de Jersey told The Courier-Mail.

All other courts in the Supreme and District Court complex were evacuated and police arrived after the security threat was raised.

The Courier-Mail reported "a large crowd" has gathered outside the court on both days to find out news about the hearing.

Davis told The Australian the case against his client is weak, adding he has been caught in "rather extraordinary allegations."
