Main opposition People Power Party(PPP) leader Jang Dong-hyeok says the judiciary's concerns about the constitutionality of two bills sought by the ruling Democratic Party represent a stern warning from the people.

Jang made the statement on Monday during a Supreme Council meeting when discussing a potential tribunal to handle martial law cases and a bill that would classify judicial perversion of justice as a criminal offense.

The PPP chief said that during a gathering last Friday, the nation's top judges pointed out the unconstitutionality of the DP's bills and clearly warned that they violate the people's right to a fair trial.

Jang criticized the presidential office for supporting the two bills after the National Assembly's Legislation and Judiciary Committee passed them last Wednesday, saying its choice revealed it to be the command center of constitutional destruction.
