A new electoral law was passed prior to the election, replacing the system in which 120 members of the Assembly were elected in single-member constituencies, with one in which 35 were elected by proportional representation at the national level, and 85 elected in single member constituencies.[3] In the single-member constituencies, candidates had to receive 50% of votes cast and 33% of the total number of registered voters to win in the first round. If no candidate achieved this requirement, a second round was held between the two candidates with the most votes.
This was the only election to use this system.[4] Prior to the 2002 elections it was replaced by a system in which the country was divided into six constituencies that elected 20 members each by proportional representation.[5]
