Number of tiers

South Africa, however, had only one tier in 1994, when the result was determined by the national vote alone.  The two tier system was introduced by the 1998 Election Act, as follows:

1998 Election Act

Schedule 1A, Section 2

2 The seats in the National Assembly must be filled as follows:

(a)  One half of the seats from regional lists, submitted by the respective parties, with a fixed number of seats reserved for each region, as determined by the Commission, for every election of the Assembly, taking into account available scientifically based data in respect of voters and representations by interested parties.

(b)  The other half of the seats from national lists submitted by the respective parties, or from regional lists where national lists were not submitted.
