OSCE/ODIHR Needs Assessment Mission Report (14 October 2012)

'Elections to the parliament are held under a parallel, mixed electoral system. The Seimas has 71 members elected in single-member constituencies under a majoritarian system and 70 members elected by proportional representation in one national constituency.

In the majoritarian contests, the winner must have an absolute majority if the voter turnout is above 40 percent. In case of lower turnout, the winner must have at least 20 percent of votes. If neither condition is satisfied and at least two candidates participated in the election, there is a runoff round between the two candidates who received most votes. In the proportional contest, an election is valid if the turnout is at least 25 percent, and a party must pass a threshold of 5 per cent in order to be awarded mandates.'
