Electoral system

Hainaut currently elects 17 of the 150 members of the Chamber of Representatives using the open party-list proportional representation electoral system.^[5][6] Seats are allocated using the D'Hondt method.^[7][8] Only parties that reach the 5% threshold in the constituency compete for seats.^[9][10]

Electors may vote for the list (party) or for individual candidates, either main candidates or substitute candidates or a combination, on the list.^[11] They may vote for as many candidates as there are seats in the constituency.^[12] Split-ticket voting (panachage) is not permitted and will result in the ballot paper being invalidated.^[13] The minimum number of votes a candidate must obtain to get elected - the quotient - is calculated as the total votes received by the party divided by the number of seats in the constituency plus one.^[14] Half the ballot papers where there are no votes for main candidates (i.e. the elector has voted for the list or for substitute candidates only) are redistributed amongst main candidates in the order they appear on the ballot paper so that the candidate's total votes (personal votes plus redistributed votes) equals the quotient.^[14] The seats won by the party are then allocated to the candidates with the most number of total votes.^[14]
