Former Cambodia National Rescue Party leader Sam Rainsy and his legal team have welcomed a California court’s indication that Facebook will be obliged to provide information related to various legal cases the self-exiled opposition figure is facing in the Kingdom.

Judge Sallie Kim said in a hearing Monday that she would “likely” instruct the social media giant to hand over pertinent data, specifically in relation to Rainsy’s domestic legal woes.

Rainsy’s head lawyer, Noah Hagey, submitted English translations of four Cambodian court documents covering four separate convictions on Tuesday, all of which stemmed from statements made by Rainsy on Facebook.

The first complaint is about Rainsy’s claim that Hun Sen buys Facebook ‘likes’. An analysis shows that a disproportionate amount of the premier’s likes originate overseas, including in countries known to harbour so-called “click farms”. The second case concerns an accusation from Rainsy that the Cambodian government was behind the murder of government critic Kem Ley, a belief that many others share. The third stems from Rainsy’s accusation that Hun Sen bribed social media activist Thy Sovantha to attack the opposition. Rainsy’s accusation was seemingly substantiated by leaked messages purportedly showing conversations between the two, although the messages have not been independently verified. The fourth case was based on a video recording of Rainsy urging soldiers not to obey orders that endanger civilians.

The submissions were made after Judge Sallie Kim said Monday she was inclined to honour Rainsy’s request for information from Facebook, but noted that the initial request was overly broad.

“I am grateful to the Court’s careful review of the Application, and to its indication that discovery of Facebook will be permitted,” Rainsy said in an email Wednesday.

He reiterated claims that Hun Sen and his “agents” have abused the platform to “defraud ordinary Cambodians during this critical time in our country”.

Hagey said the legal team continues to “be surprised by Facebook’s overly-zealous opposition to ordinary discovery of Facebook”.

Both Hagey and Rainsy suggested that the information received could “exonerate” Rainsy of his convictions in Cambodia, though the Kingdom's justice system has been regularly disparaged as a tool of the ruling party.
