Facebook plans to legally challenge Thai decision to block group

Thailand's government blocked the Royalist Marketplace group -- a page with more than one million members that discusses the country's royal family -- as the administration continues its crackdown on the growing protest movement calling for greater democracy and less power for the monarchy.

The social media giant said it was legally compelled to comply with the demand to block the group after the government threatened to pursue criminal proceedings against Facebook Thailand, but added it was "preparing to legally challenge this request."

Such requests are "severe, contravene international human rights law, and have a chilling effects on the people's ability to express themselves," a Facebook spokesperson said in a statement Tuesday. Excessive government actions undermined the U.S. company's "ability to reliably invest in Thailand," including maintaining its office and safeguarding its employees, the spokesperson added.

The move follows the arrest of protest leaders and demonstrators, including two rappers from separate anti-military music acts, who are facing charges including sedition, which carries a maximum jail sentence of seven years.

"What we have done to these pages is based entirely on Thai law -- it's not dictatorship power as I no longer have it," Prime Minister Prayuth Chan-Ocha said on Tuesday of the government's move. "If they want to take legal action, we will fight based on Thai law."

Members of the groups and protesters at recent anti-government demonstrations are breaking deeply entrenched taboos in Thailand, where openly criticizing the monarchy can lead to long prison sentences. Under the country's tough lese-majeste laws, which make it illegal to defame, insult or threaten the king, queen, heir apparent or regent, offenders can get as many as 15 years in jail for sharing a story on Facebook or hitting "like" on a post.

"Thailand's government is again abusing its over-broad and rights-abusing laws to force Facebook to restrict content that is protected by the human right to free speech," said John Sifton, Asia Advocacy Director at Human Rights Watch.

The access within Thailand to the group's page showed a message: "This content isn't available right now." The group can still be accessed outside of Thailand, although only members of the group can view the content.

The page, created in April by self-exiled academic and monarchy critic Pavin Chachavalpongpun, is highly active, with more than 10,000 posts within the last month and more than 10,000 new members over the last week.

Hours after Bangkok shut down the Facebook page, a new one from the same group had sprung up and garnered more than 500,000 members.
