South Korea political‑legal enforcement

In early July 2026, a South Korean appeals court dismissed two voters’ attempts to cast a second ballot in the 21st presidential election, upholding a 1 million‑won penalty per voter and reaffirming the one‑person‑one‑vote rule.

A week later, the Seoul Central District Court fined Mayor Oh Se‑hoon 10 million won and confiscated 21 million won for using undisclosed opinion polls and arranging payments that violated political‑fund rules. The fine exceeds the threshold that could trigger loss of his mayoral office, prompting a partisan split over whether the ruling represents justice or a politically motivated judgment.

On 22 July, Oh announced an appeal, sending the case to a higher court and potentially to the Supreme Court. The appeal process keeps the possibility of his removal pending.

On 27 July, the Democratic Party’s special committee filed a criminal complaint alleging that Oh issued false statements about the poll‑funding controversy, violating the Public Official Election Act. The committee seeks the seizure and full return of campaign‑fund refunds and warns that a conviction could force a by‑election.

These developments illustrate South Korea’s aggressive legal scrutiny of both election‑related conduct and political‑fund misuse, extending a pattern of stringent political‑legal oversight.
