July 31 (Asia Today) -- South Korea's acting prosecutor general submitted his resignation Friday after the National Assembly passed legislation eliminating prosecutors' authority to conduct supplementary investigations.

Koo Ja-hyun said he felt responsible for the overhaul of the country's criminal justice system and had submitted his resignation.

"The revision to the Criminal Procedure Act, centered on abolishing prosecutors' supplementary investigative authority, passed the National Assembly today," Koo said at the Supreme Prosecutors' Office in southern Seoul.

"I also feel a strong sense of responsibility that the law was revised while concerns raised by legal experts, other professionals and the public remain unresolved," he said.
