Changes

The parliament consists of the 460-member Sejm and the 100-member Senat, or upper house. The new constitution and the reformed administrative division (as of 1999) required a revision of the election ordinance (passed in April 2001). The most important changes were liquidation of a national list (all deputies are elected by voters in electoral districts) and introduction of a new method of calculating seats (the modified St. Lague method replaced the d'Hondt method, thus eliminating the premium for the top parties). The law stipulated that with the exception of guaranteed seats for small ethnic parties, only parties receiving at least 5% of the total vote could enter parliament.
