The society cast suspicion why the government appears slow to alert the committee.
Earlier Friday, Foreign Minister Noppadon Pattama said he plans to request for a postponement of the listing of Preah Vihear Temple as World Heritage site.
"Thailand is not in the position to support the listing at this juncture," he said.
Noppadon is scheduled to fly to Quebec tonight to attend the World Heritage Committee session.
He spoke before testifying at the Constitution Court on the legal issues relating to the temple.
