Thailand’s senate will decide Friday on whether to retroactively impeach former Thai foreign minister Noppadon Pattama for signing a statement in June 2008 in support of Cambodia’s bid to list Preah Vihear temple as a UNESCO World Heritage site, Thailand’s The Nation newspaper reported Friday. Noppadon, who served at the time under former Thai prime minister Samak Sundaravej and now works as a legal adviser for former Thai prime minister Thaksin Shinawatra, is accused of violating the Thai constitution by not consulting with parliament before signing the statement. If impeached, he faces a five-year ban from politics.
