• 1. First, the lists of political groupings whose designation was placed above a list of candidates to whom one or more seats were allocated at the last election for members of the Senate are numbered. These lists are assigned numbers 1 and subsequent numbers in the order of the votes of the respective lists at that election, with the understanding that the list of the grouping with the highest number of votes is assigned number 1. In the event of a tie, lots shall decide.

• 2. The provisions of the first paragraph apply mutatis mutandis to the merger of designations of two or more groupings if one or more seats were allocated to either the joint groupings or to at least one of them at the last election for members of the Senate. If at least one of the groups has been allocated one or more seats, for the purposes of the second sentence of the first paragraph, the votes cast on the lists of the groups to which those seats have been allocated will be added together.

• 3. The remaining lists will then be numbered, using the numbers following the last number assigned pursuant to the first paragraph, in order of the number of provinces to which the list applies, with the understanding that the next number will be assigned to the list that applies to the most provinces. In the event of an equal number of provinces, lots will be drawn.
