The new electoral law has come under wide criticism from the centre-left opposition since its introduction for a series of reasons including instability, large parties bias, partitocracy, adaptation to opinion polls, and no agreement with the opposition, as the law was passed by the majority against the opinion of the opposition. Many felt that the "rules of the game" should be agreed upon by everybody, and not imposed by one side. The system is considered by its opposers to be less stable than the previous additional member system.
