The court revoked the warrant after Jatuporn arrived at the court at 1.30pm and explained that he had no intention to delay the trial.
He is accused of defaming Abhisit during rallies in October 2009 when Abhisit was the prime minister.
Jatuporn told the court that he did not attend the morning session because he feared for his life. He said he had learned that anti-government protesters would rally at the court in the morning.
After hearing Jatuporn’s explanation, the court asked him to testify at 9am on Monday.
