Article 20 Allocation of Seats (1) The Commission shall allocate 239 seats to the provinces in the following order: 1. The total number of populations of provinces shall be divided by the 239 allocated seats to determine the population quota for each seat. 2. The population of each province shall be divided by the population quota for each seat to determine the number of seats for each province. 3. Each province is allocated a number of seats equal to the whole number from the division under clause (2) of this paragraph. 4. The seats that are not allocated under clause (3) of this paragraph, shall be allocated in the descending order of the remaining decimal fraction of the division mentioned in clause (2) of this paragraph. 5. If less than 2 seats are allocated for one or more provinces as result of this calculation, then two seats shall be allocated for that province. 6. The total seats and number of population of the provinces to which extra seats are allocated under clause (5) of this paragraph, shall be subtracted from the total of 239 seats and total population of all the provinces. For the remaining provinces, a new quota for allocation of seats shall be calculated and repeated, in accordance with the procedures described in clauses (2) and (5) of this paragraph.
