The 75 members of the First Chamber (Senate) are elected by the members of the provincial legislatures for a four year term. First Chamber elections take place about two months after provincial elections.
Since smaller provinces have relatively large legislatures, the vote of every legislator is multiplied with a vote value, which depends on the number of inhabitants. The vote values range between 96 for Flevoland and 628 for Zuid-Holland. One Noord-Holland casted an invalid vote. Residual seats are assigned by a system of largest averages (D'Hondt). When lists are combined, they are regarded as a single list when residual seats are assigned.
The First Chamber can only pass or reject bills, not amend it. Bills are only discussed when the Second Chamber has already passed them. First Chamber membership is a part time job, usually one day a week.
The parties are the same as the ones in Second Chamber, except for the Onafhankelijke Senaatsfractie (OSF). This stands for Independent Senate Fraction, its member was elected by legislators who are members of regionalist parties, (regional) parties for the elderly, or independent lists.
