The main opposition Democratic Party of Korea (DPK) is taking advantage of Justice Minister Han Dong-hoon s failed attempt to overthrow the DPK-endorsed laws aimed at weakening the investigative powers of prosecutors in its fight against the ruling bloc. Han and DPK lawmakers traded barbed remarks, Monday, when the National Assembly s Legislation and Judiciary Committee meeting took place, demanding apologies from each other by citing parts of the ruling in their respective favors.
