Electoral administration in Indonesia is complex. The Electoral Commission (Komisi Pemilihan Umum) is responsible for planning and running five-yearly elections for one national and two regional legislatures, and one additional national regional representative body, as well as direct presidential, gubernatorial, mayoral and regent elections. Because candidates and parties often have significant financial stakes in their outcome, these elections are hotly contested and the results quite commonly disputed, including in Indonesia's Constitutional Court (Mahkamah Konstitusi). Electoral contestants often point to mistakes in administration and vote counting, which appear to be natural consequences of the great logistical challenges these elections present. For example, on 17 April, 2019, well over 150 million citizens attended one of over 800,000 polling stations to vote for candidates to fill 19,817 legislative seats in national and subnational parliaments. Many of these elections are said to be marred by attempts by candidates and their parties to gain illegal advantage, whether through misuse of incumbency or vote buying. There is also said to be much potential for corruption amongst electoral administrators themselves in registering candidates, verifying parties, procuring equipment for polling stations, and counting and tallying votes on election day. Given the potential of mistakes and illegality to jeopardise the legitimacy of election results, lawmakers in Indonesia have created multi-layered oversight mechanisms to oversee the planning and running of the elections by the Electoral Commission, as well as to oversee the Election Supervisory Board (Bawaslu, Badan Pengawas Pemilihan Umum) itself, which is charged with supervising that Commission. This article examines the work and performance of these institutions, and the Electoral Administration Honour Council (DKPP, or Dewan Kehormatan Penyelenggara Pemilu), which hears allegations of breaches by the Commission and the Board.
