The bill, which calls for an investigation into Yoon, former Defense Minister Kim Yong-hyun, Army Chief of Staff Gen. Park An-su and other officials involved in the martial law declaration, passed the Assembly in a 210-63 vote with 14 abstentions.

Lawmakers of the ruling People Power Party (PPP) also cast their vote as the party earlier decided not to choose whether to vote for or reject the bill as its party line.

Prime Minister Han Duck-soo, Counterintelligence Commander Yeo In-hyung and former PPP floor leader Choo Kyung-ho were also included in a list of those subject to the investigation.
