The Assembly passed an amendment removing prosecutors' supplementary investigative power. Proponents framed it as reinforcing the separation of investigation and indictment, but critics warned it could leave gaps in investigations once in force.

The opposition People Power Party pushed back immediately, arguing the president should exercise the power to request reconsideration—a veto—and said it would file a constitutional complaint, claiming the law may be unconstitutional.

Within the ruling Democratic Party, some lawmakers voted against or abstained. Rep. Kwak Sang-eon opposed it, saying he could not back a measure whose harm to citizens was evident; reactions within the party were mixed.
