Jan. 30 (Asia Today) — South Korea’s Innovation Party said Thursday that the Constitutional Court’s decision striking down the 3% vote threshold for proportional representation is a warning to the country’s two major parties and called on the Democratic Party to amend the Public Official Election Act.
The party argued that the ruling requires broader electoral reform, including abolishing two-member local council districts, expanding regional proportional representation and introducing runoff voting for mayors and governors.
Park Byeong-won, interim spokesperson for the Innovation Party, told a news conference at the National Assembly Communication Center that the court’s decision underscored violations of popular sovereignty. He said the Democratic Party, which holds a majority in the National Assembly, should take responsibility for revising the election law.
Park said the court found partially unconstitutional a provision of the Public Official Election Act that denied proportional representation seats to parties that failed to secure at least 3% of the nationwide vote. As a result, he said, parties receiving less than 3% support will be eligible for seat allocation in the 2028 general election without further legislation.
He added that the court criticized the current system as favoring the two major parties and blocking new political forces from entering the National Assembly. Park said it would be unrealistic to expect the major parties to voluntarily reform a system that benefits them and called the ruling a rebuke that lawmakers must heed.
Park said the decision highlighted the need to abolish two-member local council districts, expand regional proportional representation and introduce runoff voting for local chief executives in upcoming local elections. He said the Democratic Party should move unilaterally to amend the election law to reflect the principle of popular sovereignty.
On Wednesday, the Constitutional Court ruled 7-2 that Article 189(1) of the Public Official Election Act was unconstitutional. The provision limited proportional representation seats to parties that won at least 3% of the national vote or secured five constituency seats.
Minor parties and candidates who failed to meet the threshold in the 21st and 22nd general elections under a semi-linked proportional representation system had filed the constitutional complaint.
