Once on-the-spot tallying is over and the tallies reported officially, the ballots are sealed and transported to the Central Election Service of the Interior Ministry. There ballots are recounted, mainly to ascertain the validity or invalidity of the few ambiguously marked ballot papers. Any unresolved matters following this recount are referred to the specially convened "Eklogodikeion" (Court of Election), which adjudicates and then officially publishes the names of elected MPs, so that the new Parliament may convene. The Court of Election may reconvene at any time to discuss appeals by candidates who failed to be elected, and also to fill seats that become vacant in the case of death or abdication of an MP. Such seats are filled by going down the preference tally of the party list that won the seat in the first place (there are no by-elections in Greece unless a party list is exhausted: an extremely rare occurrence).
