I don't remember the correct name of the form, but some details:

when you are denied entry, you can repeal and will be put in detention. Your repeal will be sent to Prime Minister and if there is no reply within 7 days, you will be granted entry. I'm looking for that form.

 

Related question: has anyone ever done it and can report? I can't imagine the Prime Minister deals with such matters.

It's called appeal, not repeal

Form TM11: https://www.immigration.go.th/download/1486548054958.pdf

You appeal to the prime minister and minister of interior, but you can write a name to which minister you appeal.

So you could write Prayut Chan-o-cha on it and then he would have to confirm your denial, if he doesn't do it they have to let you in.

No personal experience, but somebody here on Thaivisa ran into the problem that they just would not let him hand in the form.

You would also need to pay a 1900 baht fee for the appeal.

Thanks. Appeal, not repeal. That's why I couldn't find it on google or Thaivisa. Yes, that's the one I mean.

Never got denied myself but I imagine if they deny you for a bogus reason, they will just not take your form. How can you prove you tried to submit the form? Never happened.
