The Criminal Court has sentenced a red-shirt sympathiser to six years and eight months in jail for lese majeste.
The prison term is for two counts of insulting the monarchy and for an unprecedented charge of "attempting to commit a lese majeste crime".
Kittiton Yaemsamai, 50, was sentenced to 10 years in prison for posting two messages deemed defamatory to the royal family in August. On another charge, he was sentenced to three years and four months for possessing an electronic document with remarks that showed an attempt to "defame, insult and threaten the King, the Queen, the Heir Apparent and the Regent".
The court halved the sentences due to his confession, making the total jail term six years and eight months.
Yaemsamai, a father of two young children, was arrested at his rented house in Samut Prakan on Aug 30 this year.
He confessed during a police investigation and before the court in November without a further hearing or trial.
Anon Nampa, his lawyer, said the charge of "attempted lese majeste" is a new dimension on how the controversial law, which carries a punishment of three to fifteen years in prison, is being applied.
"This means having in your possession a computer with alleged lese majeste remarks that have not yet been disseminated is considered a crime under the lese majeste law. It is an expanded interpretation of the law in an unprecedented way," Mr Anon said.
