SEOUL, July 24 (Xinhua) -- South Korea's main opposition lawmakers said Friday they will continue with its firm protest against the recently-passed media reform law, vowing to take every possible measure, including resigning from parliamentary seats.

    Rep. Chung Sye-kyun, chairman of the main opposition DemocraticParty, said he submitted his resignation to National Assembly Speaker Kim Hyung-o.

    He is the second lawmaker to do so after Rep. Choi Moon-soon who formerly served as head of local broadcaster MBC.

    About 70 members of the DP's 84 legislators successively vowed to take the same measures, submitting their resignation to their party leader.

    South Korea's law allows a lawmaker's resignation only when the parliament votes for it or the Assembly speaker accepts the offer.

    Earlier on Wednesday, South Korea's National Assembly passed the government-proposed media reform bills amid harsh oppositions from the DP.

    The revision was reached during a parliamentary session attended only by lawmakers from the ruling Grand National Party (GNP), whose lawmakers went through violent physical confrontationswith the DP members to reach the voting venue.

    The opposition party has been claiming the legislation is void in that the voting procedure has been erred.

    During the session, the chairperson of Wednesday's session called a revote after declaring the completion of the first vote as he belatedly realizing that the first vote failed to meet the quorum.

    The DP is pointing out that the current law prohibits a revote on any single legislation, while the ruling party argues against them by saying that the first vote simply did not have the quorum.

    In addition to asking the Constitutional Court to nullify the media law revisions, Chung and his opposition party plan to attendstreet rallies throughout the country until the regular parliamentary session starts in September, according to DP officials.

    The newly passed media reform law, which South Korea's Lee Myung-bak regime has been pushing for since his inauguration, aims at lifting a ban on local newspaper companies from owning television channels.

    While the regime has called it as a move to promote competition of the industry, the main opposition party, together with the broadcasters and progressive civic groups, is strongly "enraged" over the move, saying it would lead to monopolies in the media industry.
