Does not matter if Pita played clean or not, do you think Pita and MF are going to be allowed to form a goverment ???
This was all designed and written into the Junta constitution; the Military/Establishment side in Thai politics knows that they are unable to win a fair or fair-ish election, so they added poison pills. Delay, Delay carry on Payut.
The EC was appointed by the Junta and will always find something to question based on their "interpretation" of the rules. Moreover, they'll take their sweet time in doing so against an opposition candidate as every day after the election goes by, the sense of momentum of the winning, Pro-Democracy side wanes just a little. Finally, after they have done their best to blunt a sense of momentum, they'll refer the case to the NACC "out of an abundance of caution" so that the new PM will be referred to as the "under investigation (insert name)".
Next is the NACC. The NACC will conduct a "fair and complete" investigation and take their sweet time about it in order to continue the policy of blunting momentum and casting aspersions on the Pro-Democracy side. Hmm... isn't Prawit's former aide still Head of the NACC?
After the NACC, the Constitution Court will weigh in. Remember them? The ones who decided that an army regulation superseded the Constitution so that Prayut could live rent-free on an army base?
The Senate. Since you all know about the Junta-appointed Senate, I won't waste my time.
The process is clear as day.
"Concerns" will be raised. Bull<deleted> rules and regulations will be cited. "Doubts" will be cast. "Questions" will be asked.
In August , approximately four months after the election, when the momentum from the election has worn off and the leading candidate or candidates from the opposition side have been tarnished in the name of "making sure everything is correct", then they will decide if they want the tarnished candidate or they decide that "more investigations" are needed to "ensure fairness" and muddy it up further.
This is all by design and was planned a few years ago.
