Day One in Court: 5 Key Issues in Seoul Mayor Oh Se-hoon's Blanket Denial of 'Poll Payment Cover-Up' Charges
Seoul Mayor Oh Se-hoon attended his first trial hearing at the Seoul Central District Court on March 4, 2026, charged with violating the Political Funds Act for allegedly having associates cover the costs of opinion polls commissioned from political broker Myung Tae-kyun ahead of the 2021 Seoul mayoral by-election. He denied all charges. With the June local elections approaching, the trial outcome is being watched as a major variable in the Seoul mayoral race.
Why you should pay attention now: With just 90 days to go before the June local elections, the biggest wild card in the Seoul mayoral race opened in court today.
TL;DR
- Seoul Mayor Oh Se-hoon appeared at the Seoul Central District Court on March 4, 2026 for the first hearing in the 'Myung Tae-kyun poll payment cover-up' case.
- The charge: violating the Political Funds Act by allegedly receiving opinion poll services from political broker Myung Tae-kyun ahead of the 2021 by-election and having associates and donors cover the costs.
- Oh's legal team denied all charges, stating: "There was no instruction to commission polls, and no arrangement for anyone to cover the costs."
- At the same time, they raised the possibility of political prosecution, questioning the timing of the indictment relative to the election calendar.
- A January court ruling that acquitted First Lady Kim Keon-hee on a similar charge in the same Myung Tae-kyun case may influence the outcome of Oh's trial.
1. The Facts — What Happened
Seoul Mayor Oh Se-hoon is accused of receiving opinion poll services from political broker Myung Tae-kyun during preparations for the 2021 Seoul mayoral by-election and arranging for third parties — associates and donors — to cover the costs (estimated in the several million won range). Prosecutors and the special counsel (Special Prosecutor Min Jung-ki) charged Oh with violation of the Political Funds Act.
Mayor Oh appeared in person at the Seoul Central District Court and stated before the presiding judge:
*"I neither instructed anyone to conduct opinion polls, nor did I arrange for anyone to cover the costs."
2. Why It's Exploding Now — Key Factors
| Factor | Explanation |
|---|---|
| D-90 to Local Elections | The Seoul mayoral race is heating up with just 90 days to go before the June local elections |
| The Myung Tae-kyun Fallout | An extension of the 'Myung Tae-kyun Gate' entangling Yoon Suk-yeol, Kim Keon-hee, and multiple PPP figures simultaneously |
| Kim Keon-hee Acquittal Precedent | A January court ruling found the poll reception charge not guilty — potentially forming favorable precedent for Oh's defense |
| Both Parties on Alert | The opposition is pressing on 'political funds corruption'; the ruling party is pushing back with 'political prosecution' framing — both sides weaponizing the trial for the election |
3. Context — What Is the 'Myung Tae-kyun Gate'?
Myung Tae-kyun provided opinion poll services to key People Power Party figures around the 2021–2022 by-elections, general elections, and presidential race, and became the center of various allegations including interference in candidate nominations and illicit financial arrangements. The special counsel has been sequentially indicting politicians connected to Myung, and Oh Se-hoon stands out as a sitting metropolitan mayor among those charged.
On January 28, the court acquitted First Lady Kim Keon-hee of charges that she received Myung's poll services without payment (Political Funds Act violation), ruling that "Myung provided them voluntarily for business purposes." Oh's defense team is invoking this verdict in arguing for their client's innocence.
4. Outlook — How Far Does This Go?
- Short-term (1–3 months): Political sparring will continue as hearings proceed. A first-instance verdict before the June election appears unlikely given the schedule.
- Medium-term (before the election): Rather than the verdict itself, the ongoing trial proceedings will weigh on Oh's campaign. Opposition candidates will repeatedly use the trial as attack material.
- Long-term: When the Myung Tae-kyun-related trials wrap up (second half of 2026 to 2027), the final outcome could reshape the political and administrative landscape of Seoul.
