The Criminal Court is expected to reveal who was behind the killing of a red shirt demonstrator in Bangkok two years ago.
The court's ruling is scheduled for Nov 26 at 9am.
The case concerns the death of Channarong Polsrila, who was shot in front of a Shell petrol station on Rang Nam Road in Phaya Thai district on the night of May 15, 2010.
At the time, the Abhisit Vejjajiva government had imposed a state of emergency in Bangkok, with red shirt demonstrators occupying parts of the capital.
The court heard testimony yesterday from the last two witnesses called by lawyers representing Channarong's family. They were Suthep Thaugsuban, former deputy prime minister who oversaw security measures against red-shirt protesters at the time, and Deputy Agriculture and Cooperatives Minister Natthawut Saikua, who led red-shirt protesters.
Mr Suthep said in his capacity as then-director of the now dissolved Centre for Resolution of the Emergency Situation, he ordered officials to block people from entering red-shirt protest sites and instructed officials to take action in accordance with international standards.
He testified that officials were told to use only shields, clubs, rubber bullets, tear gas and water cannons. Only commanders were allowed to carry pistols, rifles and live ammunition to defend themselves and others _ but they were not allowed to kill anyone.
Mr Natthawut said the previous government had not followed international standards for controlling demonstrations. The government deployed snipers who killed many people, he said.
The court's decision next month will mark the second time it has ruled on the causes of death during 2010's political violence.
On Sept 17, the court ruled that gunfire from a military unit killed taxi driver Phan Khamkong on the night of May 15, 2010.
