South Korean lawmakers passed an amendment to extend the second comprehensive special investigation period by 30 days [1].

The extension allows investigators more time to uncover facts in a high-profile probe while intensifying a legislative battle over the legal powers of state prosecutors.

The amendment passed in the National Assembly in Seoul after the conclusion of an unlimited-debate filibuster [1]. Under the new terms, the investigation deadline is moved to the 23rd of next month [1]. To support the extended timeline, the maximum number of dispatched investigators has been increased to 150, which is an increase of 20 personnel [1].

The legislative process highlighted deep political divisions. To force the end of the filibuster, a minimum of 180 seats was required [1]. The effort was led by the Democratic Party and supported by other political factions.

Rep. Jeon Eun-soo of the Democratic Party said, "Truth must be identified and revealed. Only a special prosecutor can do that."

However, the move faced criticism from the opposition. Rep. Kim Tae-gyu of the People Power Party said, "The majority of the people will think so. That the regime is carrying out such a bloody revenge and catching people like that."

Beyond the timeline and staffing, the amendment process revived a broader debate regarding the legal system. Specifically, lawmakers are clashing over whether to abolish the supplementary investigation authority currently held by prosecutors [1]. This authority allows prosecutors to conduct further inquiries into cases, a power that critics argue can be misused for political purposes.

Truth must be identified and revealed. Only a special prosecutor can do that.

The extension of the special investigation signifies a continuing power struggle between the legislative branch and the executive's prosecutorial arm. By increasing both the timeframe and the manpower, the National Assembly is signaling a lack of confidence in standard prosecutorial processes. The renewed debate over 'supplementary investigation authority' suggests that the outcome of this specific probe may lead to a systemic overhaul of how criminal investigations are managed in South Korea.
