On April 22, 2026, the Seoul High Court delivered a decisive ruling in one of South Korea’s most closely watched political disputes of the season, rejecting Joo Ho-young’s appeal to suspend his exclusion from the People Power Party’s (PPP) nomination for Daegu mayor. The decision, covered by multiple major outlets including Dong-A Ilbo, News1, Hankyoreh, Kyunghyang Shinmun, and Law Times, marks the latest—and perhaps final—turn in a legal battle that has gripped party insiders and local voters alike.
The origins of this dispute trace back to March 22, 2026, when the PPP’s nomination committee announced that Joo Ho-young, a sitting National Assembly Deputy Speaker and a well-known figure within the party, along with Lee Jin-sook, would be excluded from the party’s preliminary candidate pool for the Daegu mayoral race. The committee’s decision was part of a broader review of nine potential candidates, ultimately resulting in the exclusion of three, including Joo. According to Kyunghyang Shinmun, the committee made its decision after evaluating all nine candidates, not just a select few, and concluded that the process was procedurally sound.
Joo, who has long been considered a political heavyweight in Daegu and beyond, responded swiftly. On March 26, he filed an injunction with the Seoul Southern District Court, seeking to suspend the effect of his disqualification. The case, registered as 2026카합1176, was closely watched by legal experts and political commentators, who debated whether party nomination processes should be subject to judicial intervention.
On April 3, the first trial court dismissed Joo’s injunction. The court’s reasoning, as reported by Hankyoreh and Kyunghyang Shinmun, was clear: “With the evidence submitted by Joo, it is difficult to conclude that the People Power Party grossly violated its own rules or conducted an objectively irrational review. There is no clear proof of a serious illegality.” The court further emphasized that party nominations are “high-level political decisions,” and, compared to disciplinary actions, the autonomy of party activities must be more strongly protected.
Undeterred, Joo appealed the decision on April 8. He held a press conference at the National Assembly, stating, “I will make my final decision about my course of action after seeing the outcome of the appeal.” This comment, faithfully reported by Hankyoreh, signaled both his disappointment and his intention to exhaust all legal avenues before determining whether to pursue an independent run or withdraw from the race altogether.
The appeal was formally registered as case 2026라2475 and assigned to the Seoul High Court’s Civil Division 25-1, presided over by Chief Judge Lee Kyun-yong. On April 22, the court delivered its ruling, again rejecting Joo’s request to suspend the effect of his disqualification. The reasoning, as summarized by Kyunghyang Shinmun, was that the nomination committee had properly assessed all nine candidates and that its decision to exclude three, including Joo, was made in accordance with established procedures. The court also stated, “The nomination committee’s cut-off decision does not infringe on Joo’s right to run for office.”
This was not the first time that the courts had weighed in on the boundaries of party autonomy in candidate selection. The latest rulings reinforced the judiciary’s longstanding reluctance to interfere in what it views as the internal, political decisions of parties. According to Dong-A Ilbo, the court explained, “Nomination is a highly political decision, and the autonomy of party activities must be more strongly respected than in disciplinary cases.”
For Joo Ho-young, the back-to-back defeats in court have left his political future uncertain. The immediate effect of the ruling is that he remains excluded from the PPP’s official candidate list for the June 3 local elections. As of late April, PPP members Yoo Young-ha and Chu Kyung-ho have advanced past the preliminary round and are preparing for the main contest to become the party’s standard-bearer in Daegu, as reported by News1. The focus now shifts to whether Joo will pursue a run as an independent candidate—an option some party insiders and local observers believe could shake up the race and potentially fracture the conservative vote in a city long considered a stronghold for the PPP.
The broader implications of the court’s decision are already being debated within political and legal circles. Supporters of the PPP’s leadership argue that the ruling affirms the party’s right to manage its own affairs and maintain discipline within its ranks. “The committee reviewed all nine candidates and made its decision in accordance with the rules. There is no procedural flaw,” one party official told Kyunghyang Shinmun on condition of anonymity.
Critics, however, question whether the party’s nomination processes are truly transparent and fair, or whether they are susceptible to internal factionalism and power struggles. Some argue that the exclusion of high-profile figures like Joo could alienate segments of the electorate and damage party unity ahead of a crucial election. “This case shows how internal party decisions can have far-reaching consequences, not just for the individuals involved, but for the party’s image and its relationship with voters,” said a political analyst quoted by Hankyoreh.
Legal experts, meanwhile, see the rulings as a reaffirmation of the principle that courts should intervene in party affairs only in cases of clear illegality or gross procedural violations. “Without clear evidence of a breach of party rules or irrational decision-making, the courts are unlikely to second-guess political judgments,” said one Seoul-based attorney familiar with election law, as summarized by Law Times.
As the June 3 local elections draw nearer, the PPP’s nomination process for Daegu mayor remains a focal point for political intrigue and speculation. The party’s leadership is keen to move past the controversy and rally support behind its chosen candidate, while Joo Ho-young’s next move is awaited with bated breath by both supporters and opponents. Whether he chooses to run as an independent or step back from the race, his experience is likely to fuel ongoing debates about party democracy, candidate selection, and the role of the judiciary in South Korean politics.
For now, the courts have spoken, and the People Power Party’s decision stands. The Daegu mayoral race enters its next phase—one candidate lighter, but with no shortage of drama or significance for South Korea’s political landscape.
