South Korean President Moon Jae-in has signed a bill to revise the nation's Constitution, changing the rules on the president's duties and authority. The proposals still need approval by the National Assembly. Shane Hahm has more from Seoul.  

SHANE HAHM SEOUL "A government proposal to amend South Korea's constitution now heads to the legislature. At the heart of this issue is cutting back on the president's authority, and diversifying that power into the prime minister and the National Assembly. Many here argue there's just too much power vested in the presidency and so it makes the position more susceptible to corruption, as evidenced by the on-going trials currently of two former presidents. The government is suggesting allowing two successive four-year presidential terms, as opposed to the current single five-year term. President Moon would not be subject to this amendment. Other measures include allowing the Constitutional Court to appoint its own chief justice, instead of the president nominating a judge, and also more oversight into presidential pardons. These proposals would need approval from the parliament, but I went around the streets of Seoul to see what South Koreans think about these proposals."

HAM SONG-E SEOUL RESIDENT "There are still many supporters of past presidents Lee Myung-bak and Park Geun-hye. Many of them are against the government proposal. I think the opinions of these people need to be collected and more political support is needed."

LEE JOON-HO SEOUL RESIDENT "A constitutional revision must satisfy all citizens. I think it's being rushed. Not enough time has passed since the president was inaugurated."

SHANE HAHM SEOUL "This bill would need to pass a two-thirds vote in the legislature, which now has 60 days to review and approve. The government wants to see a national referendum vote on this in June in time for local elections. But opposition lawmakers are saying the timing of this proposal is politically motivated to win more votes and say more time is needed to deliberate."
