The one reason for his detention was his possible tampering with witnesses, which meant that Glavas, who was taken to custody on 26 October, could be released after a one-month detention during which witnesses could be questioned in the pre-trial proceedings about war crimes committed in Osijek in late 1991.
The other reason for the prosecution to ask for his detention was the gravity of the crime. The judge who is conducting an investigation in Glavas and Krunoslav Fehir on suspicion that they committed war crimes against local Serbs in the eastern city of Osijek in 1991, granted this request of the prosecution three days ago.
After a panel of judges of the Zagreb County Court on Friday quashed the appeal which Glavas's defence team lodged regarding the issue of the gravity of crime, the decision became final and the suspect can no longer appeal it, the spokesman for the Zagreb County Court, Kresimir Devicic said.
"Further detention of Glavas in custody now depends on the decision of the Croatian Parliament," the court spokesman said adding that he could not speculate about the outcome of the parliamentary debates and voting on the matter.
Earlier on Friday, the Sabor decided to postpone the vote on reports by Credentials and Privileges Commission to strip independent MP Branimir Glavas of immunity, as the ruling Croatian Democratic Union (HDZ) wanted to hold additional intra-party consultations.
The Commission asked the parliament to okay the stripping Glavas of immunity and approving his detention in custody also on the basis of gravity of crimes.
Independent member of parliament Glavas, suspected of 1991 war crimes in Osijek, has been in detention in Zagreb since 26 October this year after the Zagreb County Court investigating judge ruled that he should be remanded in custody.
Also on 26 October, the parliamentary Credentials and Privileges Commission granted the repeated request by the Zagreb County Court to strip Glavas of immunity so that he could be remanded in custody due to possible witness tampering in the investigation launched against him and Fehir.
The Commission also proposed that the Parliament strip him of immunity so that Glavas could be held in custody due to gravity of crimes, which seems to be a contentious issue.
This Wednesday Sabor Speaker Seks, who is also a high-ranking HDZ official, said that his party would not support the decision by the parliamentary Credentials and Privileges Commission (MIP) approving the detention of independent MP Glavas on grounds of the gravity of the crime he is suspected of, but would only support his detention on grounds that he might tamper with witnesses in the war crimes investigation that was being conducted against him by a Zagreb court.
Glavas has been on hunger strike for 20 days which is why he has been admitted to the prison hospital.
