South Korea constitutional amendment vote fails due to opposition boycott

South Korea's National Assembly declared a vote on a proposed constitutional amendment invalid Thursday after a boycott by the opposition party ^[1].

The failure to reach a quorum stalls a significant effort to alter the nation's foundational law. This deadlock highlights the deep political divide in Seoul as lawmakers clash over the limits of executive power and the timing of legislative changes.

The vote took place on May 7, 2026 ^[1]. The session was intended to address a proposal backed by six parties ^[1]. However, the People Power Party (PPP) boycotted the plenary session, which prevented the assembly from meeting the required quorum to make the vote legally binding ^[1], ^[2].

Members of the ruling Democratic Party (DP) said the amendment was necessary to establish stronger safeguards against the declaration of martial law ^[1], ^[2]. They said the changes would protect democratic stability by limiting the circumstances under which such emergency powers could be invoked.

Opposition lawmakers from the PPP said the amendment was politically motivated ^[1], ^[2]. The PPP said the move was designed to benefit the ruling party ahead of upcoming local elections rather than to serve a genuine constitutional necessity.

The National Assembly in Seoul remains the center of this legislative struggle. Because the PPP refused to enter the chamber, the session ended without a result ^[1], ^[2].

This is the second time this month that legislative progress has been hampered by quorum disputes. The ruling party continues to push for the amendment, while the opposition said the proposal is a tactical maneuver to sway voters in the next election cycle ^[1], ^[2].
