South Korea’s ruling and opposition parties are expected to face a legislative confrontation during the 100-day regular National Assembly session beginning September 1. The agenda includes real estate supply and price stabilization, follow-up legislation to abolish prosecutors’ supplementary investigation authority, capital-market reforms and next year’s budget, projected by the government at around 800 trillion Korean won. The National Assembly will hold a plenary session on September 3, followed by policy speeches from the Democratic Party of Korea and People Power Party negotiation representatives on September 7–8. Government questionings will take place over four days, September 9–11 and September 14, covering politics, diplomacy, unification, security, the economy, society, education, culture and overall state affairs. Further plenary sessions are scheduled for September 17 and October 1, while a three-week audit of state affairs begins October 6. The Democratic Party has prioritized price stabilization, real estate policy, support for small business owners and capital-market reform. Its proposed legislation includes revisions to the Urban Planning Act, establishment of a Real Estate Supervision Agency, amendments to the Inheritance and Gift Tax Act known as the Stock Price Suppression Prevention Act, and a revision to the Yongsan Park Special Act. The parties disagree over housing supply in the Yongsan Park area, where the Ministry of Land, Infrastructure and Transport and Seoul City Hall have conflicting views. The Democratic Party also plans legislation supporting government projects in semiconductors, data centers and physical AI, including amendments to five laws, and may debate exempting the Mega Special Zone Special Act from the 52-hour workweek. It plans to use the fast-track system, whose maximum deliberation period was recently reduced to 90 days under revisions to the National Assembly Act. The People Power Party has selected 133 legislative tasks across seven areas under its reviving the people’s economy platform and is preparing filibusters against Democratic Party bills. It supports abolishing the reconstruction excess-profit recapture system, preserving urban green space in Yongsan Park, advancing police reform after the false closure of a missing persons case in Jeju, and restoring the independent inspector general selection process, which has been dormant for nearly a decade. The Democratic Party is also likely to pursue the 7 Major Crimes Mandatory Referral bill, covering vulnerable-group crimes including child abuse, domestic violence, sexual crimes, child sexual abuse, stalking, disability abuse and elder abuse. A super week of confirmation hearings will address 10 personnel reshuffles announced by Cheong Wa Dae. Budget negotiations will include the government’s priorities of AI and the three mega-projects, aerospace and bio-industries, youth support by growth stage, responses to K-shaped polarization and region-led growth, and public safety. The opposition strongly opposes the 100 trillion Korean won Future Response Fund, which would use additional tax revenue from the semiconductor boom.
