The Criminal Court of Thailand on October 6 dropped a petition from deposed Prime Minister Yingluck Shinawatra, which accused judges of being unfair in their handling of charges against her.
The court announced it will not accept the case, saying it found no evidence of any abuse by prosecutors.
On September 29, the ousted former PM submitted a petition to the Bangkok Criminal Court, alleging judges had stood together to protest her government in the multi-billion dollar rice-buying scheme.
In the petition, Yingluck said investigations carried out against her have not been sufficient and the additional documental evidence were not in the earlier case files of the National Anti-Corruption Commission (NACC).
The former PM also denounced the judges as illegally using additional documents as evidence in the trial process.
In January 2015, the National Legislative Assembly of Thailand casted a vote to blame Yingluck Shinawatra for the rice buying scheme that incurred big losses.
Yingluck faces up to 10 years in jail if she is found guilty of negligence.
Yingluck was removed from office in May 2014 after a court found her guilty of abusing power, days before the army staged a coup after months of street demonstrations in Bangkok.
She has defended the policy which bought rice from farmers at above-market prices. The ruling junta said the rice scheme was tainted by grafts and caused 16 billion USD in losses.
In January, Yingluck was banned from politics for five years after a military-backed legislature found her guilty of corruption relating to the rice subsidy scheme.-VNA
