Here are the facts, from Prachatai, which includes a photo:
On 28 December 2013, the defendants, together with other PDRC protesters, barricaded a Nakhon Si Thammarat candidate registration office. The protest prevented the local Election Commission from registering candidates. As a result, the general election could not be held in all nine Nakhon Si Thammarat constituencies on 2 February 2014.
Nakhon Si Thammarat was one of eight southern provinces which their candidate registrations for the 2014 election were disrupted by the anti-election protesters.
Nakhon Si Thammarat prosecutors indicted them for preventing the election.
Remember all that horse manure spread by the military junta about “reconciliation”? Here’s how the judiciary interprets it:
The court ruled that when the defendants were charged the political environment in Thailand was very divisive and all the prosecution witnesses were political opponents of the defendants. Therefore the evidence was weak….
Ignore the facts, the video evidence, the prosecutors and the case that comes from the police investigations and, most of all, ignore law when it is not politically acceptable. There are no double standards anymore, not under the military dictatorship. There are just the junta’s views, needs, desires and wants.
