[JURIST] Amnesty International (AI) [advocacy website] on Friday called for a public trial [press release] for a Thai political activist accused of insulting the royal family. Judge Prommat Toosang on Wednesday ordered [Reuters report] that the trial of Darunee Charnchoengsilpakul [advocacy website] be closed for national security reasons. AI's Asia-Pacific director Sam Zarifi noted that although the closure of trials is legitimate under the International Covenant on Civil and Political Rights (ICCPR) [text] and the Thai Constitution [text, in Thai], the government "will have a very difficult time explaining why the trial of someone charged with making an insulting remark could compromise Thailand’s national security." Zafiri said that Prommat's guarantee of a fair trial was inadequate and "simply not verifiable" unless the trial is conducted in public.

Darunee was arrested [The Nation report] last July on charges of violating Thailand's lese majeste [UPI backgrounder] law, which prohibits defaming, insulting, or threatening "King, the Queen, the Heir-apparent, or the Regent." Darunee is accused of denouncing the royal family during a July 2008 speech [video, in Thai] while speaking at a political rally for the United Front for Democracy against Dictatorship (UDD) party of ousted prime minister Thaksin Shinawatra [BBC profile; JURIST news archive]. Thaksin was removed from power in 2006 by a military coup and was later as convicted on corruption charges [JURIST reports] by the Supreme Court of Thailand.
