 In order to increase proportionality, the law provided that if parties reaching the five per cent threshold got in total 50 per cent or less of the vote, parties with at least 3.0 per cent of the vote would also win seats by declining numbers of votes up to the point at which the total share of vote exceeded 50 per cent.However, if after this procedure the parties winning seats still had less than 50 per cent of the vote, the election was to be deemed invalid.In the single-member district ballots, if votes cast against all exceeded the votes of each candidate, a repeat election had to be held within four months.
