Before the announcement of the verdict, Cacic's defence team and prosecutor Krisztina Kostyak will give their closing arguments at a session scheduled for 9 am tomorrow.

At the last main hearing on June 21, two expert witnesses who had already differed in their opinions whether Cacic had driven too fast or not when his Chrysler hit a Skoda Fabia on the Nagykanisza-Budapest motorway in January 2010, reiterated their assessments.

Expert Zoltan Lovasz, who previously testified that the accident had been caused by speeding, insisted that Cacic had driven between 140 and 150 kilometres per hour when the accident happened, adding, however, that a margin of error was between 10 and 15 percent, which meant that the speed of Cacic's car might have ranged between 125 and 165 km/hr. Lovasz also insists that Cacic failed to adjust his driving to the conditions on the road. Cacic, however, claims he had been driving at 125 km/hr, which was below the limit of 130, and that he had entered a patch of fog when he hit the car in front of him.

Expert Mihaly Rektor, who already claimed that the speed of Cacic's car had not been excessive and that the two passengers in the Skoda Fabia sustained fatal injuries when their car crashed into the motorway barrier, said that after studying additional expert materials on this matter, he had come to the conclusion that Cacic had been driving at the speed of 135 km/hr. This expert said that only the Skoda driver had her seatbelt on, while other passengers in her car were unbelted. He went on to say that after the crash, Cacic's car slowed down to 120 km/hr, while the Skoda's speed accelerated to between 100 and 120 km/hr and hit the safety fence, which he deems to have been fatal.

Katalin Liptak, the Skoda Fabia driver insists that Cacic should be held accountable for the fatal accident in which she lost her 81-year-old mother and 60-year-old husband. They died of injuries sustained in the crash some time after the accident.

At his arraignment in late September 2011, Cacic said he felt responsible and expressed regret, but rejected the charge that he had driven too fast, claiming that visibility had been poor.

In his later comment to the press, the Croatian official said that "accidents cannot be reasons for resignations" and that "if there is responsibility, then one can resign," although some time ago he had announced his withdrawal from politics in the event of a non-suspended prison term for the crash.

Croatian Prime Minister Zoran Milanovic said that the traffic accident involving Cacic was "ethically neutral" which was why he would let Cacic decide whether he would remain in his cabinet or resign following the court's judgement.
