The Special Tribunal for Lebanon in January delivered a sealed indictment to tribunal judges. The indictment is widely expected to point the finger at Hezbollah, which led opposition leaders in a January walkout that brought down the government of Saad Hariri, the son of Rafik Hariri.
Members of the Shiite elite in Lebanon said the STL has lost constitutional legitimacy. The tribunal has been turned into a political tool rather than a venue for justice, they said.
"Therefore, the (Shiite) council calls (on the Lebanese government) to reject any cooperation with it because it has bypassed the state, the constitution and the people," Lebanon's Daily Star newspaper quoted the Shiite elite as saying in a statement.
Washington and the United Nations have urged Prime Minister-designate Najib Mikati to ensure that any new government honors its international obligations.
Mikati, a former ally of Saad Hariri, hasn't been able to form a unity government because of disputes between the Western-backed March 14 coalition and the March 8 alliance, which includes Hezbollah.
