system The law maintains the electoral system used in 2014, using the open list system. Voters could vote directly for the candidate they wanted in a list of candidate names presented by party. The candidates are then ranked by vote in their respective parties, and the party's quota is determined through the Webster/Sainte-Laguë method after elimination of parties not meeting the threshold. For presidential candidates, the winning candidate is determined by simple majority, with runoff voting for the top two candidates if no candidates managed to secure a first round majority. In addition, the winning candidate must secure at least 20% of votes in over half of the provinces (i.e. more than 17).:Art. 416 Thresholds During the previous election, parties are required to pass a parliamentary threshold of 3.5% in order to be represented in the People's Representative Council. The law increased this threshold to 4%. The presidential threshold was decided at the 25%/20% option, in which parties would need a total of 20% (112 for the 2019 election) legislative seats from the 2014 election, or 25% of the popular vote from 2014. The threshold does not apply to local legislative elections, and all participating parties may win seats in provincial and municipal councils regardless of their total national vote. Others The law increased limits to campaign contributions – from Rp 1 billion to Rp 2.5 billion for individuals, and Rp 7.5 billion to Rp 25 billion for legal entities or corporations. In addition, it allowed political parties which participated in the 2014 election to skip party verification, despite the addition of North Kalimantan as a province requiring party offices. Lawsuit The law has been challenged in the Constitutional Court. A lawsuit by Vice President Jusuf Kalla on the term limits set by articles 169 and 227 was rejected in June 2018. A judicial review was also submitted regarding the presidential threshold (art. 222). A lawsuit to article 182, which did not explicitly prohibit political party functionaries to be elected into the Regional Representative Council, won in July 2018.
