Pol General Patcharawat Wongsuwan petitioned the Administrative Court in 2009, accusing Abhisit of refusing to reinstate him without justification.
Patcharawat oversaw the anti-riot operations that caused casualties on October 7, 2008, in connection with the blockade of Parliament by the yellow shirts.
The National Anti-Corruption Commission had ruled that Patcharawat had committed a serious disciplinary offence related to dereliction of duty, resulting in his dismissal from the police force.
