Majority legislators gathered in the Lebanese Parliament building in Beirut on Tuesday, to urge the Lebanese speaker of the house, Nabih Berri, to open the first session of parliament for the year.
The pro-government anti-Syrian camp wants Parliament to convene so that the creation of an international tribunal to try suspects in the February 2005 assassination of former Prime Minister Rafik Hariri could be ratified.
The Hezbollah-led front has demanded modifications to the proposal for the international court.
On Tuesday, key negotiations were ongoing between Berri and Saad Hariri, the head of the majority legislators.
Saad Hariri is a Sunni Muslim and his community backs Prime Minister Fuad Saniora's pro-Western government.
Berri is a Shiite Muslim, and his party Amal and its Hezbollah ally draw their support from the country's Shiite community.
The Christian community has lent more support to the anti-government faction than the pro-government.
Pro-government legislators launched a scathing attack on Berri, dealing a blow to negotiations between the two sides.
Musbah Al-Ahdab, a pro-government Member of Parliament (MP) said the Lebanese parliament had "been totally paralysed."
"I think that we need to find a constitutional platform, we need to have this parliament to start working again," he said. "It is about time to bring back discussions where discussions should be, I mean in the parliament, the Lebanese parliament."
Another MP, senior Druse leader Walid Jumblatt, accused Berri of hijacking parliament upon orders from Iran and Syria.
Anti-government MPs however said Tuesday's gathering in parliament would undermine dialogue between Berri and Hariri.
"We consider this atmosphere of exaggeration and escalation to be a stab for this dialogue and the meetings which are going on," MP Ali Bazzi said.
"It seems that they (majority legislators) have deprived the government of its legitimacy, constitutionality and credibility and now they are trying to deprive the parliament of its legitimacy," he added.
The opposition and Lebanon's pro-Syrian President, Emile Lahoud, considers Saniora's government to be unconstitutional after five Shiite ministers and a pro-Hezbollah Christian minister resigned in November.
