The People's Alliance for Democracy (PAD) will on Monday demand a clarification from the junta about its alleged failure to prevent the escape of former prime minister Yingluck Shinawatra out of the country.
The PAD on Saturday issued a statement at its Ban Phra Arthit headquarter, noting that Ms Yingluck's exit out of the country has undermined public trust in the judicial system and the security mechanism.
PAD spokesman Panthep Puangpongpan said a key member of the movement, Mr Veera Somkwamkid, would on Monday travel to the Government to demand accountability of those in charge of security affairs.
Ms Yingluck didn't show up at the Supreme Court's Criminal Division for Holders of Political Offices to hear the verdict on the rice pledging scheme case on Friday, claiming she was suffering from Miniere's disease.
Constitution Drafting Commission chairman Meechai Ruchupan, meanwhile, defended that it was not the fault of the government, the National Council for Peace and Order or the police for Ms Yingluck's escape out of the country.
He explained that state authorities could not detain or closely follow her because this may infringe upon her right's of free movement as she is not found guilty of breaking the law.
He, however, insisted that Ms Yingluck has the right to appeal the Supreme Court's verdict under a provision of the new constitution.
