The Bangkok Post reports that a “group of activists is filing a petition with the National Anti-Corruption Commission (NACC) against the Election Commission (EC) for organising what it said was an unfair and objectionable referendum.”
A little like protesting the EC’s failure to organize elections in 2014, protesting the junta’s referendum is unlikely to change anything in that military-supported and supplicant agency. That said, making the protest stakes out an important position: the referendum was nothing like transparent, free or fair.
Many flaws are mentioned by Srisuwan Janya, from the group, the Association for the Protection of the Constitution. Yet the focus is mainly on the referendum itself. Much of the damage to the referendum was done in the months prior to it being held when the military and its minions began campaigning.
Other problems with the referendum have been noted and listed by various groups. All are potentially serious. We can only wonder at how widespread these were. Of course, the junta allowed only a few observers and did not permit truly independent and organized observation.
