The key point of the trial is whether Mayor Oh commissioned public opinion polls several times through Myung Tae-gyun and had his acquaintances pay for them. The special prosecutor's team believes that Mayor Oh violated the political fund law by communicating with Mr. Myeong through former Vice Mayor Kang Cheol-won, who was his chief of staff, to secure public opinion polls to use in his election strategy, and by having businessman Kim Han-jung bear the costs. On the other hand, Mayor Oh admits to having met with Mr. Myeong, but completely denies the charges, saying that he ended the relationship due to low evaluation of the reliability of the information he provided. While Myeong's side claims that Mayor Oh requested an investigation in the past to defeat candidate Na Kyung-won, Mayor Oh strongly opposes this claim, saying it is groundless sophistry aimed at clouding judicial judgment, making it even more difficult to establish the facts.

It appears that this trial has gone beyond a legal dispute and has degenerated into a harsh frame war of 'underlying investigation' and 'planned prosecution'. Immediately after appearing in court, Mayor Oh directly attacked the Special Prosecutor Min Joong-gi's team, calling it a vicious organization that abused its judicial power to achieve political goals. In particular, he said that placing him as a defendant in line with the local election schedule was an intentional plan to destroy his political career, and even hinted at the possibility of accusing the special prosecutor's team of distorting the law depending on the results of the trial. Mayor Oh emphasizes that he tried to prove his innocence by voluntarily submitting his cell phone during the investigation, and claims that this trial will be the end of a flawed investigation in which the criminal and the victim were switched.

Along with the legal battle, changes in the power landscape within the People Power Party are also becoming important variables in this case. Mayor Oh poured out sharp criticism toward Jang Dong-hyuk, leader of the People Power Party, who strongly insisted on requesting re-election after the June 3 local elections, clearly revealing the cracks in leadership within the party. Mayor Oh said that Representative Jang's push for re-election was nothing more than a political slogan to strengthen his political position, and devalued the leadership of Jang Dong-hyuk, saying that his leadership had already reached its end of its lifespan. This goes beyond simple response to the trial and shows how the fight for leadership within the party will unfold in conjunction with the external variable of the trial, foreshadowing that the People Power Party's struggle over the line will intensify in the future.

This case, which involves the Public Official Election Act and the Political Fund Act, is a serious matter that will directly lead to Mayor Oh losing his position even if a fine of 1 million won or more is confirmed. Since both the continuity of Seoul's administration and the next political move depend on the judicial procedures following the first trial ruling, the judiciary's judgment after this trial carries greater weight than ever before. With Mr. Myeong's claim and Mayor Oh's wife in a tense conflict, the political situation will once again be shaken depending on what evidence the court adopts and what legal interpretation it presents. Ultimately, this case is a test of whether the judiciary can block external political pressure and draw wise conclusions based only on the substantive truth.
