The public session at which the Supreme Court will discuss Cacic's appeal to a decision by a panel of Zagreb County Court judges entirely confirming an earlier ruling by a Hungarian court in Kaposvar, is scheduled for 11 am on April 24.

Cacic's defence counsels had previously said that they would request a 'slightly shorter sentence' as a drastically reduced or conditional sentence, even if approved by the Supreme Court, would most likely be rejected by the Hungarian judiciary.

Confirming the Hungarian court's verdict, Zagreb County Court in January this year ruled that after serving at least half the sentence, Cacic would be eligible for parole. He was further banned from driving for a period of three years.

The final ruling in the trial for the accident in which two people were killed was passed down by the Hungarian court in late November 2012. Cacic immediately stepped down from office as first deputy prime minister and economy minister and lodged a plea with the Hungarian court to allow him to serve his sentence in Croatia.

The Hungarian court issued provisional approval which means that a final decision by the Croatian court needs to be accepted and endorsed by the Hungarian justice minister and only then will Cacic be allowed to serve his sentence in one of Croatia's prisons.
