It's become the favored strategy of opposition lawmakers protesting - and hoping to prevent - a vote for president.
Tensions have been building in the country since Foreign Minister Hashim Thaci -- the current top presidential contender -- brokered a deal with Serbia that gave more power to the ethnic Serb minority in Kosovo.
Opposition supporters have been rallying outside.
Parliamentary police are preparing for a possible escalation, while inside, officials warn that a failure to elect a president will lead to parliament's dissolution and snap elections within 45 days.
