Accused wife murderer Gerard Baden-Clay returned to court in Brisbane on Monday for legal argument ahead of his upcoming trial.
The routine hearing to determine which evidence can be put before a jury is scheduled to run for two days in the Brisbane Supreme Court.
Dressed in a dark suit and wearing a tie, the 43-year-old former real estate agent watched proceedings from the dock.
The court heard from the pathologist who carried out Allison Baden-Clay's post-mortem examination.
Legal argument centred on the admissibility of parts of his evidence, and that of medical experts who assessed scratches and other marks found on Baden-Clay following his wife's disappearance.
The couple's former family counsellor is expected to give evidence in court for the first time when the hearing resumes on Tuesday.
Mrs Baden-Clay, 43, was reported missing by her husband on April 20, 2012.
Her body was found 10 days later on the banks of a creek in Brisbane's west.
