In Slovakia's system of proportional representation, the parties needing the fewest votes to get to their next quota are given the remaining seats.
If this system had been applied in Slovakia, it would have resulted in the quota being reduced to 45960 (5.55% of the total), with the remaining 3 seats going to SDKU, SMK and SNS.
The 11 candidates elected due to personal preferences included 3 (KDH's Anna Záborská and Miroslav Mikolášik as well as SNS's Jaroslav Paška) whose list positions did not in themselves justify a seat so could be said to have been elected solely by preferential voting.
The remaining 8 candidates (SMER's Boris Zala, Vladimír Maňka and Monika Flašíková – Beňová, the SDKU's Eduard Kukan and Peter Šťastný, the SMK's Edit Bauer and Alajos Mészáros as well as the HZDS's Sergej Kozlík) all would have been elected anyway if there was no preference voting in the system (as in some other member states) and the party list ordering had been used alone.
It is important to note however, that these 8 people would not have been elected if their personal voters had chosen other candidates, so they were not in any way guaranteed seats as a result of their list positions.
