The Constitutional Court of South Korea has officially opened the trial of President Yoon Seok-yeol's impeachment case. The trial process first enters the "preliminary court" stage, which is also called the "pre-court meeting". During the preliminaries, the Constitutional Court will organize one or more court sessions so that the prosecution and defense parties - the South Korean National Assembly and Yoon Seok-yeol - can focus on their respective positions, claims, evidence and focus of debate.

In addition, Yoon Seok-yeol submitted a power of attorney. His legal agent team includes Bae Bo-yoon, a former constitutional researcher at the Constitutional Court, who served as the spokesperson for the Constitutional Court during the impeachment trial of former President Park Geun-hye. This is the first positive response from Yoon Seok-yeol to the impeachment trial.

After the preliminaries, the Constitutional Court will choose an appropriate time to start the court debate between the two sides and finally announce the verdict. This process may take several months, and the final result of Yoon Seok-yeol's impeachment case will have a significant impact on the political situation in South Korea.
