The Lawyers Council of Thailand has filed an official request with the Koh Samui Provincial Court asking it to summon witnesses living in and foreign countries to testify for the defence in the Koh Tao double-murder case.
The council, which is representing defendants Zaw Lin and Wai Phyo of Myanmar, submitted the request on Tuesday morning, but the court has yet to decide if it will accept the proposal, lawyer Surapong Kongchantuk, told the Bangkok Post.
Mr Surapong declined to elaborate on the details of the local and foreign witnesses he seek to appear in court.
The two Myanmar men are accused of killing British backpackers Hannah Witheridge and David Miller on Koh Tao Sept 15. They additionally face several other charges, including raping Witheridge.
Since the murder, a large number of Myanmar nationals have fled Koh Tao. The pair's defence team has been urging the Myanmar community - both in Thailand and at home - to locate witnesses that help the two men.
