Australian Jock Palfreeman's case in Bulgaria's highest court is expected to be heard two weeks earlier than scheduled.
The Supreme Court of Cassation had been due to review the 32-year-old's parole on October 23 but the court has announced the case will now go ahead on October 7, the ABC reports.
"Due to to the extraordinary public interest in the trial and due to the information that Jock Palfreeman, who has been granted parole, cannot move freely because of the upcoming decision to be made by the Supreme Court of Cassation, I find that we should allow the opportunity to hear the case sooner," the Supreme Court of Cassation's deputy head said in a statement.
Palfreeman, of Sydney, was sentenced to 20 years' jail in 2009 for the fatal stabbing of law student Andrei Monov during a brawl in 2007.
He was granted parole by Bulgarian authorities last month after serving more than 11 years behind bars.
His release was met with outrage in Bulgaria and prompted the country's prosecutor-general to lodge an extraordinary petition to suspend Palfreeman's parole and review the ruling from the Court of Appeals.
