The former premier complained to the Supreme Court’s Criminal Division for Political Office Holders on Friday that a series of investigations had been launched into her witnesses.

She lodged a complaint on a day when her twelfth defendant witness gave evidence.

Former agriculture minister Yukol Limlaemthong testified in regard to the ministry’s zoning of rice growing and regulations to enter the scheme put in place during the Yingluck government’s rice mortgage scheme to ensure transparency.

Yingluck has been charged with negligence in her oversight of the scheme, which was allegedly plagued with corruption.

The former PM presented a complaint that witnesses were subject to fresh probes by a sub-panel of the National Anti-Corruption Commission after they testified before the court. She believed such action was unfair.

The court acknowledged her complaint but said it had no authority to order other organisations to stop performing their duty. But it would record this in the case report.
