Several groups of people in the current political conflict have filed petitions and counter-petitions in the courts and with independent agencies, with rulings expected sooner or later.
"We don't want to see a ruling or a decision by an independent agency being used to foment conflict in society. Everyone should respect the justice process and let everything proceed under normal circumstances within the scope of the law," said the army spokesman.
Asked about the checkpoints set up in Bangkok and other provinces, he said they there to watch for untoward incidents, reduce violence, screen out war weapons, and help the people.
They were not set up to help a particular side in the politcal conflict, he said.
Col Winthai asked the people not to infringe on the rights of other people, particularly by making insulting remarks or expressing hatred for individuals or organisations, or threatening to use force against others.
