Former Deputy Prime Minister Damir Polancec had also been a suspect in the case, but USKOK recently gave up prosecuting him because it had not found any evidence of Polancec aiding and abetting Sanader in the abuse of office.
Before issuing the indictment, the prosecutors failed to obtain a deposition from the suspect Hernadi, although they had requested it from their Hungarian colleagues. According to media reports, the Hungarian authorities explained their rejection by saying that the transfer of requested information would pose a threat to Hungary's security. Some 20 days later, an agreement was reportedly reached on transferring the prosecution of Hernadi to Hungary.
The investigation of the former Croatian prime minister for taking 10 million euros in kickbacks from MOL was launched in mid-June.
In October 2010, more than six months before the investigation was initiated, Sanader testified on INA-MOL relations before the Croatian Parliament fact-finding commission on the privatisation of INA. He said then that all he had done was for the benefit of Croatia, telling his former party colleagues that they were risking "falling into their own trap."
According to his lawyers, Sanader also rejected all the accusations in this case when questioned by USKOK investigators about it in August in Zagreb's Remetinec prison where he has been held since mid-July when Austria extradited him to Croatia to face accusations of corruption. He repeated then that all government ministers, coalition partners and the then President of the Republic, Stjepan Mesic, were acquainted with the details of the agreement with MOL.
His defence team claimed at the time that the case was launched based on a deposition by the owner of the petrochemical company Dioki, Robert Jezic, who, by blaming Sanader, tried to secure a better position for himself in proceedings against him. A half of the 10 million euros were allegedly been paid through Jezic's companies in Switzerland.
On 31 August USKOK filed the first indictment against Sanader, accusing him of abuse of office as a deputy foreign minister in 1994 and 1995 and taking HRK 3.6 million in kickbacks for a loan the government obtained from Austria's Hypo bank.
